Astronomers witness 'one of the most extraordinary black hole systems' - CNN

The black hole, known as V404 Cygni, doesn't behave like others. The jets shoot out possibly within minutes of each other and in all different directions. And while the researchers admit that black holes are some of the most extreme objects in the universe, this one is different.
"This is one of the most extraordinary black hole systems I've ever come across," study author James Miller-Jones said in a statement. Miller-Jones is also an associate professor at Curtin University's International Centre for Radio Astronomy Research.
The study published Monday in the journal Nature.

"Like many black holes, it's feeding on a nearby star, pulling gas away from the star and forming a disk of material that encircles the black hole and spirals towards it under gravity," he said. "What's different in V404 Cygni is that we think the disk of material and the black hole are misaligned. This appears to be causing the inner part of the disk to wobble like a spinning top and fire jets out in different directions as it changes orientation."
The black hole was first discovered in 1989 because it released jets and radiation. Previous outbursts associated with this black hole were noted in 1938 and 1956 and found on archival photographic plates.
V404 Cygni caught the attention of astronomers around the world when it unleashed another bright outburst that lasted for two weeks in 2015. Telescopes everywhere trained on the event, which led to a wealth of observational data.
Normally, jets shoot out from the poles of black holes. These jets were firing off in different directions at different rates over a couple of hours.
Astronomers have found the fastest-growing black hole ever seen, and it's got a monster appetite
The black hole itself is rotating and the gravitational pull is so strong, it's actually pulling nearby space and time around with it. This is called frame-dragging.
The material in the jets is blasted out from the black hole's rotating accretion disk. The disk forms when material from a nearby star is pulled into a circle around the black hole.
For scale, the black hole is nine times more massive than our sun and V404 Cygni's disk is 10 million kilometers across. The jets shoot out material at 60% of the speed of light.
Because the spin axis of the black hole is misaligned, frame-dragging also warps part of the disk, causing an intense wobbling that is responsible for the jets shooting off in different directions.
These are the first massive black holes from the early universe
"This is the only mechanism we can think of that can explain the rapid precession we see in V404 Cygni," Miller-Jones said. "You can think of it like the wobble of a spinning top as it slows down, only in this case, the wobble is caused by Einstein's general theory of relativity."
The researchers had to use a different technique to capture what was happening in the black hole. Normally, they use long exposures.
"These jets were changing so fast that in a four-hour image we saw just a blur," said Alex Tetarenko in a statement, another of the study authors and East Asian Observatory Fellow.
Instead, 70-second-long individual exposures were combined to make a film of the action the astronomers were witnessing.
"We were gobsmacked by what we saw in this system — it was completely unexpected," said Greg Sivakoff in a statement, study author and associate professor at the University of Alberta's department of physics. "Finding this astronomical first has deepened our understanding of how black holes and galaxy formation can work. It tells us a little more about that big question: 'How did we get here?'"

The 2018-2019 Broadway season hurtled to a close, with 14 plays and musicals opening in March and April, before the Tony Award nominations were announced on Tuesday morning. And some of the late entries into the race were handsomely rewarded.

Hadestown, a retelling of the Orpheus and Eurydice myth by singer-songwriter Anaïs Mitchell, opened just two weeks ago and took 14 nominations, including one for best musical. Another recent entry, a reworking of the 1980s film comedy Tootsie, took 11 nominations, also including best musical.

Rounding out the best musical category were a jukebox musical, Ain't Too Proud: The Life and Times of the Temptations, with 12 nominations; an adaptation of the film Beetlejuice, with eight; and an original musical, The Prom, with seven.

One of the biggest surprises of the season was the sheer number of new plays produced on Broadway: 14. Best play may be the hardest Tony category to predict.

The Ferryman, Jez Butterworth's family drama set in Northern Ireland during the "troubles," led the pack with nine nominations, followed closely by Taylor Mac's idiosyncratic Gary: A Sequel to Titus Andronicus, with seven, and Ink, a British import about young Rupert Murdoch, with six.

Rounding out the category were two Broadway debuts: Choir Boy, by Tarell Alvin McCraney — winner of an Academy Award for Moonlight — and What the Constitution Means to Me, a personal memoir written and performed by Heidi Schreck.

Two popular plays also captured several nominations, but not for the top prize. Aaron Sorkin's adaptation of Harper Lee's To Kill A Mockingbird, starring Jeff Daniels, received nine nominations, and an adaptation of Paddy Chayefsky's Network, starring Bryan Cranston, got five. Both of those lead actors were nominated in the best actor in a play category.

The best play revival field is particularly strong, with The Boys in the Band, The Waverly Gallery, All My Sons, Burn This and Torch Song all up for top honors. And only two musical revivals were eligible for best musical revival: an avant-garde staging of Rodgers and Hammerstein's Oklahoma!, which received eight nominations in total, and a revised version of Cole Porter's Kiss Me, Kate, which took four.

In addition to Daniels and Cranston, several big stars were nominated for top awards, including Adam Driver in Lanford Wilson's Burn This, Annette Bening in Arthur Miller's All My Sons, Elaine May in The Waverly Gallery and Kelli O'Hara in Kiss Me, Kate.

Some other stars were left out of their categories, including Glenda Jackson, who won a best actress Tony last year and starred in King Lear this season, and Nathan Lane, who leads Gary.

A complete list of nominations is available at the Tony Awards website.

The Tony Awards will be presented on Sunday, June 9 at 8 p.m. Eastern time. The ceremony will be hosted by James Corden at Radio City Music Hall and broadcast on CBS.

Apple stock falls ahead of earnings as Samsung, Google warn of smartphone issues - MarketWatch

Apple Inc. is about to give its take on smartphone demand, but not before its chief rivals painted a bleak picture of the current landscape.

Both Alphabet Inc. GOOGL, -8.09% GOOG, -8.15%  and Samsung Electronics Co. Ltd. 005930, -0.65% reported earnings late on Monday, alluding to continued slowdowns in their smartphone businesses.

“Hardware results reflect lower year-on-year sales of Pixel reflecting in part heavy promotional activity industry-wide given some of the recent pressures in the premium smartphone market,” Alphabet Chief Financial Officer Ruth Porat said on the company’s conference call.

She later tried to soften the blow by maintaining that while smartphone sales were down, Google Home smart speakers and other home devices have been demonstrating “ongoing momentum.”

Opinion: Google sales growth is slowing, and it sure would be nice to know why

Samsung predicted a “likely stagnant smartphone market” in the second half of the year and described how it’s had to adjust to changing conditions. Robert Yi, the company’s head of investor relations, explained that “the process of revamping our mass-market lineup amid softer overall smartphone demand” prompted a drop in sales volume for Samsung in the latest quarter.

When Apple AAPL, -1.71%  reports earnings this afternoon, a key focus will be on the company’s performance in China, after challenges there prompted the company to report a disappointing holiday quarter. Apple has cut prices in China as a result, but Samsung’s commentary suggests that the issues in China aren’t product specific, with Vice President Sang-Hyun Lee informing investors that the first quarter marked the start of “weak seasonality” in the region.

Apple earnings: How much of its massive cash pile will go into investors’ pockets?

Analysts are divided on what Apple’s China numbers will show, as Credit Suisse’s Matthew Cabral predicts that the company won’t be able to show “meaningful improvement” until it launches 5G iPhones in 2019. Morgan Stanley’s Katy Huberty is more upbeat, writing of her expectation that Apple saw “further iPhone stabilization in March.”

Apple shares were down 1.8% in afternoon trading Tuesday, while Alphabet shares were off 8.3%.

Venezuela uprising live updates: Opposition leader Juan Guaido calls for military uprising against President Nicolas Maduro; Military commander calls it a "coup attempt" - CBS News

Video in the player above shows Venezuelan opposition supporters clashing with security forces.

Venezuelan opposition leader Juan Guaidó took to the streets with a small contingent of heavily armed troops early Tuesday in a bold attempt to lead a military uprising against President Nicolas Maduro.

The early-morning rebellion seems to have only limited military support, but it was by far the most serious challenge yet to Maduro's rule since Guaidó declared himself the country's interim president in January.

The dramatic events began Tuesday when Guaidó, flanked by a few dozen national guardsmen and some armored vehicles, released a three-minute video filmed near a Caracas air base in which he called on civilians and others in the armed forces to join a final push to topple Maduro.

"The moment is now," Guaido said in the video showing him accompanied by previously-detained activist Leopoldo Lopez.

Maduro's military commanders dismissed what it called a "coup attempt" in social media posts and said the Venezuelan army remained loyal to the president.

Live updates:

UN chief urges "maximum restraint"

The U.N. says Secretary-General Antonio Guterres is urging all sides in Venezuela to exercise "maximum restraint," avoid any violence and take immediate steps to restore calm. Guterres' "message publicly and privately has been to push for dialogue in order to resolve this peacefully," U.N. spokesman Stephane Dujarric told reporters Tuesday.

Dujarric said the U.N. is "reaching out to both sides." He noted that Guterres met Venezuela's Foreign Minister Jorge Arreaza last week and met Monday with the Lima group of countries supporting Guaidó. Dujarric also said the U.N. is taking measures to ensure the safety of its staff in the country.

Street clashes erupt

Venezuela's Juan Guaidó calls for military uprising

Anti-government demonstrators clashed with troops loyal to Maduro at an air base in Caracas, the country's capital, hours after Guaidó's attempt to lead a military uprising.

Video showed unrest, including clashes.

NBC News tweeted a video it said showed an armored military vehicle ramming into pro-Guaidó protesters in the city.

Internet restrictions reported in Venezuela

Venezuela's state run internet provider has been restricting access to YouTube and Google services following the opposition leader's call for the military to revolt against Maduro, a group that monitors internet censorship said.

The non-governmental NetBlocks group said access to the services remains intermittently available since the restrictions don't appear to be completely effective. It said Twitter, Facebook and several other services were briefly restricted earlier, although core internet connectivity remains unaffected.

The group said past incidents of network filtering in Venezuela have lasted from 12 minutes to over 20 hours.

Google did not immediately respond to a request for comment.

Defense minister rejects attempt by "subversive movement"

The events appear not to have triggered a broader military revolt. Defense Minister Vladimir Padrino on Twitter rejected what he called an attempt by a "subversive movement" to generate "panic and terror."

The ruling socialist party chief, Diosdado Cabello, said most of Caracas was calm and called on government supporters to amass at the presidential palace to defend Maduro from what he said was a U.S.-backed coup attempt. About a dozen government supporters, some of them brandishing firearms, gathered at the presidential palace, answered the call.

"It's time to defend the revolution with arms," Valentin Santana, head of a militant group, said in a video posted on social media as he brandished an automatic rifle.

Meanwhile, Guaidó said he would release a list of top commanders supporting the uprising in the coming hours.

Putin discusses uprising with his top security body

Russian President Vladimir Putin has discussed the ongoing uprising in Venezuela with his top security body. Putin raised the current developments in Venezuela during his scheduled meeting with the Security Council, Russian news agencies quoted Kremlin spokesman Dmitry Peskov as saying.

Peskov said that the meeting "paid significant attention to the news reports about a coup attempt in that country." He did not elaborate further.

Pence: "We are with you!"

U.S. Vice President Mike Pence tweeted "We are with you!" Tuesday to the Venezuelans taking to the streets after Guaidó's call for an uprising.

"America will stand with you until freedom & democracy are restored," he added.

The U.S. and dozens of other countries have recognized Guaidó as Venezuela's rightful leader, arguing that Maduro's re-election was invalid.

The White House later said it is "watching and waiting" on the situation in Venezuela and hoping the result is democracy.

It was unclear how much advance knowledge the Trump administration had of Guaido's plans for Tuesday, but President Trump's national security adviser John Bolton was first to tweet his support.

"The United States stands with the people of Venezuela," Bolton tweeted.

A post-action analysis of GoT's Battle of Winterfell—through a glass, darkly - Ars Technica

Halfway through the last season of Game of Thrones, we put together an after-action analysis of the major military engagements driving the plot of the series in the season's two central episodes—"The Queen's Justice," in which the forces allied against Queen Cersei got seriously pasted, and "The Spoils of War," in which Daenerys Targaryen, her dragons, and her Dothraki rapid response force swept down on the Lannister army's wagon train and turned it into a macabre cookout.

Now we're halfway through the final season of the series, and we're at a similar pivot point. The second episode of the season—"A Knight of the Seven Kingdoms"—laid out the somewhat awful strategic position of the combined allied forces under the command of Daenerys Targaryen and her Warden of the North, lover and likely nephew Jon Snow. And in the most recent episode—"The Long Night"—that situation reached its climax and conclusion in what could set the record for the least number of photons registered in a film or video production of its length ever.

As we were writing this, we were beaten to the punch by one of our favorite military Twitterati and bloggers, Angry Staff Officer, a master of fictional tactical interpretation, in his excellent but perhaps slightly misguided analysis for our sister publication, Wired. It's definitely worth reading, and you should do so right after you read this—unless you have not seen the episode and are averse to spoilers. In that case, come back and read both once you're ready.

Situational awareness

At first (like the first two minutes), it seems we have a steady human set of hands at the wheel...

HBO

Dany's Dothraki and Unsullied forces, Jon's army of the North, the remaining Night's Watch, the remnants of the Brotherhood Without Banners, and a sundry assortment of other good guys face a dire strategic situation to start. The Night King and his mega-army of risen dead people have them outnumbered; he can challenge their air superiority with his own undead dragon and proven anti-aircraft spear; and instead of getting reinforcements from the double-dealing Queen Cersei, they get a one-handed man famous for pushing a kid out a window and siring kids with his sister.

At their command post in Winterfell, the collected leaders looked at the bleak situation and laid out their battle strategy: hold out as best as possible while luring the Night King into a single combat situation using warg raven/drone operator and cryptic intelligence provider Bran Stark (that kid who got pushed out the window) as the bait. Then they mostly get drunk and wait for the onslaught, until forward scouts signal that the enemy is near. But other than toots on a horn, Dany's leadership has absolutely no battlefield situational awareness. It's like they don't have any sort of flying thing that could do reconnaissance or something.

While scouts have given a rough estimate of force composition and the order of battle is pretty well-known, there's pretty much no operational picture—and pretty much no television picture, either, as the director of photography chooses to present the first half of the episode mostly in various shades of black. As the battle approaches, flame priestess and general portent of doom Melisandre wanders up and provides some much needed lighting—giving the Dothraki cavalry some flaming swords to swing. Meanwhile, non-combatants are withdrawn to the super-safe crypt, surrounded by dead people who could be raised by the Night King. Nobody seems to think twice about this, not even Dany's supposedly savvy advisors Tyrion and spymaster Varys—but we've seen them fall flat on their faces before in the foresight department, so that's not a shocker.

Dany and Jon watch from a mountaintop vantage point, awaiting their cue to deliver air support. They can't see much of anything. But somebody eventually does, as the Dothraki charge the unseen White Walker line.

Leeroy Jenkins time

This will totally work.
Enlarge / This will totally work.

There has been a lot of criticism of the Dothraki cavalry charge. But we are here to say that the criticism should be focused on the lack of close air support. In "The Spoils of War," the Dothraki served as a "fixing force" to line the Lannisters up for mass destruction from the air. Here, the Dothraki are literally lighting the way to the enemy, and all they have is some artillery support in the form of catapulted flaming tarballs.

Had this illumination been used for, say, some timely dragon strafing by Dany while Jon flew combat air patrol above, the Dothraki sacrifice may have been considerably smaller. Instead, we just get to see their flaming swords extinguished by the advancing line of we don’t know what.

The primary failure of the Dothrakis' use as a shock force was that they ran into an enemy (literally) that could not be shocked. Hopefully there are enough of them left to play a role in the next engagement.

The Dothraki charge was just another example of how utterly unimaginative Dany's supporting staff have been in the face of new challenges. As the returning Dothraki retreat back to Winterfell, we get a good look at another major failure of imagination—the defensive works around the castle, which are, to be honest, embarrassing even from a medieval tactical perspective. While the defenses may have been rushed a bit, it's hard to believe nobody remembered that the enemy's main body was a relentless, berserker undead infantry. Winterfell's outer defensive works were:

  • A line of chevaux-de-frise—spiked anti-cavalry fortifications akin to tank traps
  • A trench filled with stuff that burns

That's it. There were no other engineering efforts made. There was no effort to use the moving mass of the Walkers against them, using stake walls or other defensive structures. There could have been concentric trenches. Nope. And the Unsullied and Dothraki and everyone else on the field before Winterfell had to retreat through the defenses, causing higher losses.

Sure, all of this would have taken time and resources. But even a little more effort could have bought more time. Unfortunately, this bit of tactical and strategic fail is often reflected in reality, where commanders go into battles thinking the enemy will just fight them by the rules they already know.

Combined arms… and legs

When in doubt, have a witch light a bunch of trenches on fire.
Enlarge / When in doubt, have a witch light a bunch of trenches on fire.

Command, control, and communication is essential on the battlefield. But the Night King essentially jammed Winterfell's C3 efforts by bringing on a literal fog of war—masking the battlefield with Winter itself. Davos Seaworth waves those flaming sticks to signal to Dany to dragon-flame the trenches alight, but she can't see anything through the low deck. Fortunately (?), Melisandre goes out and does her thing one more time, setting the trench alight.

And then everybody just stands there and watches each other. All the catapults are outside the walls and the trenches. All the archers sit on their hands as the Walkers pause at the wall of flame. Another opportunity to thin the (easily replenished) ranks of the dead.

Meanwhile, Dany and Jon get tangled up in an air-to-air engagement with the Night King, astride his zombie, blue-fire spitting dragon. The Night King has failed to master the use of air power: he could have ignored Jon and Dany and just leveled Winterfell's walls with airstrikes like he did to that Other Wall, but nah. He obviously has no understanding of air-to-air tactics and attempts an attack from below—only to end up entangled with one of his targets. Both the Night King and Jon end up un-dragoned, their reptilian aircraft left to their own devices.

But this is not an apparent problem for the Night King, who has psychic C3 over his minions—and is able to raise all the dead around him as reinforcements. Dany tries to toast the Night King with dragon fire, but it's super-ineffective.

The Night King directs his dead troops to breach the burning barrier in a style reminiscent of World War I trench warfare (or, as Angry Staff Officer put it, "Soviet style")—by throwing their bodies down as a bridge over the obstacle. Suddenly, the lines are not so static. The walls are breached World War Z style by the masses of White Walkers. As the battle rages inside the walls, the Night King strolls into Winterfell with his squad of frozen bros.

The plan… works?

Then, there is a lot of dying. Jon finds himself tied down by zombie dragon fire. Dany is defended to the death by Jorah Mormont after her dragon gets weighed down by White Walkers. Theon Greyjoy and a band of archers defend Bran at the bait-point to the end, before Theon is dispatched with his own spear by the Night King. It looks like this is the end… until Game of Thrones' ultimate special warfare operator, Arya Stark, arrives and dispatches the Night King with some really slick Valyrian steel dagger work. The King crumbles, and his minions all collapse. It's like a proton torpedo down the exhaust port. The end.

It's a win, at huge costs—one that considerably weakens Dany's fighting force for the coming battle with Cersei's mercenary reinforcements and fleet. But the win shows that the basic underlying strategy mapped out by the leadership was correct—even if the execution left much to be desired.

In the end, we believe that the Battle of Winterfell played out much as most military conflict does. Success in combat often hinges upon the determination, imagination and ability to adapt and overcome in the face of situations that soldiers haven't trained for. The enemy will not always conform to your tactical paradigm. And fortune favors the bold.

If you want the show's writers to justify the action of team human, HBO's latest behind the episode video does just that.

NASA head issues meteor warning, calls for cooperation to meet threat - NBCNews.com

/ Source: CNBC.com

By Chloe Taylor, CNBC

Meteors that could destroy an entire U.S. state are a real threat to Earth, NASA’s chief warned on Monday.

Speaking at the Planetary Defense Conference in Washington, D.C., NASA Administrator Jim Bridenstine warned that the risk posed by meteor crashes was not being taken seriously.

“This is not about Hollywood, this is not about movies, this is about ultimately protecting the only planet we know right now to host life,” he said.

Bridenstine pointed to the meteorite that exploded over the Russian city of Chelyabinsk in 2013, which had “30 times the energy of the atomic bomb at Hiroshima” and injured around 1,500 people. Just 16 hours after the crash, NASA detected an even larger object that approached the earth but did not land on it, he revealed.

“I wish I could tell you that these events are exceptionally unique, but they are not,” Bridenstine said. “These events are not rare — they happen. It’s up to us to make sure that we are characterizing, detecting, tracking all of the near-Earth objects that could be a threat to the world.”

According to scientific modeling systems, such events are expected to happen once every 60 years — but Bridenstine pointed out that destructive meteorites had crashed on the earth three times in the last century.

In 2018, the White House published an action plan that required NASA to detect, track and characterize 90 percent of near-Earth objects measuring 140 meters (460 feet) in diameter — but Bridenstine admitted on Monday that the space agency had a long way to go to meet that goal.

“We’re only about a third of the way there,” he said. “We want more international partners that can join us in this effort. We want more systems on the face of the Earth that can detect and track these objects, and we want to be able to feed all of that data into one single operating system so that ultimately, we have the best, most accurate data that we can possibly get.”

Bridenstine warned that failing to invest in such a network could have catastrophic consequences.

”(At 140 meters) it’s big enough to destroy a state in the United States of America,” he said. “It’s big enough to destroy an entire European country.”

“We know for a fact that the dinosaurs did not have a space program,” he added. “But we do, and we need to use it.”

Earlier this month, NASA awarded a contract to Elon Musk’s SpaceX that will see the company provide launch services for the agency’s Double Asteroid Redirection Test (DART) mission. The $69 million mission, expected to launch in 2021, will test the earth’s capability of deflecting an asteroid by colliding a spacecraft with it at high speed.

Elizabeth Warren rips Chase Bank over 'Monday motivation' tweet - Fox Business

JPMorgan Chase CEO Jamie Dimon doesn't see a recession coming

FoxNews.com columnist Liz Peek, former investment banker Carol Roth, former Pennsylvania governor Ed Rendell (D) and Kaltbaum Capital Management President Gary Kaltbaum on JPMorgan Chase CEO Jamie Dimon’s claim that the U.S. won’t see a recession for the next few years.

Sen. Elizabeth Warren, D-Mass., ripped Chase Bank after the financial institution tweeted a “Monday motivation” tip to customers with low bank account balances.

Continue Reading Below

Chase’s now-deleted post featured a fictional conversation between a person and their bank account, in which the person ignored money-saving tips like making their morning coffee at home instead of buying it at a store. The tweet drew immediate backlash on social media from many critics, including Warren, who saw it as a tone-deaf attack on lower-income Americans.

MORE ON THIS

Mimicking the format Chase used in its original tweet, Warren pointed out that the bank received a $25 billion taxpayer-funded bailout in the wake of the 2008 financial crisis. The 2020 presidential hopeful also reiterated her common assertion that leading employers don’t pay a living wage to their employees.

A frequent critic of corporate malpractice, Warren emerged as Wells Fargo's staunchest detractors after the bank was linked to a series of scandals related to its sales practices.

Live Updates: Clashes Flare After Venezuela Opposition Leader Calls for Military Uprising - The New York Times

• Clashes between anti-government protesters and law enforcement officers erupted in Caracas on Tuesday after the Venezuelan opposition leader, Juan Guaidó, appeared alongside soldiers at a military base and called for the population to rise up against the president, Nicolás Maduro.

• While Mr. Guaidó has exhorted the Venezuela military to join his side since he declared himself interim president more than three months ago, it was a new step for him to make the declaration with men in uniform by his side. Still, it was unclear how much of the military supports him.

• The Trump administration, which has backed Mr. Guaidó since he first declared himself interim president in January, expressed immediate support for his latest move. “Estamos con ustedes! We are with you!,” Vice President Mike Pence said in a Twitter post.

Mr. Guaidó, whose effort to topple Mr. Maduro has made little headway since he declared himself interim president in January, took a new step by making his case publicly at a military base in the heart of the capital.

“Today, brave soldiers, brave patriots, brave men attached to the Constitution have followed our call,” Mr. Guaidó said in a video posted on social media, speaking from Generalissimo Francisco de Miranda Air Base, a military airport in Caracas known as La Carlota.

Mr. Guaidó claimed that “the definitive end of the usurpation starts today,” but it was not clear how many civilians or soldiers would heed him.

Behind Mr. Guaidó stood Leopoldo López, a member of his party who received a nearly 14-year sentence after staging protests in 2014 and has been held by the government under house arrest. Mr. López did not speak in the video but issued messages on Twitter saying that he had been released by soldiers.

“I was released by the military on the order of the Constitution and President Guaidó,” he wrote in his first Twitter posts since 2017. “Everyone mobilize. It’s time to conquer for freedom.”

Speaking to reporters near the airstrip, Mr. Guaidó said that a wide swath of the military now backed him, including top commanders, but he declined to release their names.

“There are generals, there are lieutenant colonels, there are majors, there are colonels — it’s a reflection of the country,” he said.

President Maduro insisted in a Twitter post that the military was on his side, saying commanders had assured him of “their total loyalty to the people, to the Constitution and to the fatherland.”

Jorge Rodríguez, the government’s information minister, said on Twitter that government was “confronting and deactivating a small group of military traitors” that he said had taken over the base “to promote a coup.” He blamed the “coup-mongering ultraright,” which he said had pushed for a violent agenda for months in Venezuela.

National guard soldiers and policemen fought against anti-government protesters who were beginning to assemble for a protest in response to Mr. Guaidó’s call. Witnesses said tear gas canisters could be seen detonating near the military base.

The government and supporters of Mr. Guaidó had encircled Mr. Maduro’s presidential palace by midmorning.

Videos posted on social media showed a crowd of protesters approaching the air base, waving Venezuelan flags.

“I believe this is very important, but I see apathy and fear in people,” said one of the protesters, Mary Galaviz, 69. “We should not be afraid. In war there is death, but goals are achieved.”

Miriam Segovia, 52, another protester near the base, said she hoped that the armed forces would “put themselves on the side of the Constitution, so we can escape this misery, this hunger and lack of medication.”

Battered by mismanagement, American sanctions and corruption, the Venezuelan economy has been in steep decline since 2014. Millions of people have emigrated, and the roughly 30 million who remain are plagued by hyperinflation and shortages of medicines, food, electricity and jobs.

Mr. Maduro, who has been in office since 2013, won re-election last year in a contest that was widely seen as fraudulent. In January, the National Assembly, controlled by the opposition and led by Mr. Guaidó, declared the election and the government illegitimate, leading Mr. Guaidó to claim to be the rightful, transitional leader.

More than 50 countries, including the United States and most of its close allies, recognized him as Venezuela’s legitimate leader.

On Tuesday morning, Vice President Mike Pence reiterated American support for the opposition, posting a message of encouragement on Twitter: “To @jgauido, the National Assembly and all the freedom-loving people of Venezuela who are taking to the streets today in #operacionlibertad — Estamos con ustedes! We are with you! America will stand with you until freedom & democracy are restored. Vayan con dios!”

‘Game Of Thrones’ Battle Of Winterfell Hits All-Time Series & HBO Viewership High – Update - Deadline

SPOILER ALERT: This article contains details of the third episode of Game of Thrones Season 8 that aired on April 28. 

UPDATE, 8:34: The linear numbers for Games of Thrones‘ hand-to-hand and sword-to-sword filled April 28th “The Long Night” episode scored the second best numbers for the HBO series ever.

However, now that the premium cabler has released HBOGo and HBO Now numbers, the third episode of the Emmy winning series’ final season is now the most watched ever.

That’s most watched GoT and most watched HBO series ever in the history of the WarnerMedia-owned outlet.

Topping the previous record of the Season 8 “Winterfell” opener of April 14, “The Long Night” snagged 17.8 million viewers over all platforms and with two linear airings.

“The Long Night” bested the “Winterfell” episode by just 3% in gross audience – but a win is still a win not matter how close.

PREVIOUSLY, 7:52 AM: We don’t know yet who will sit on the Iron Throne but the third episode of the final season of Game of Thrones gave us the battle of all small screen battles and a near record viewership result for HBO.

Clocking in at 82 minutes, the Miguel Sapochnik-directed “The Long Night” is the longest episode so far of the David Benioff and D.B. Weiss executive produced blockbuster series based on George R.R. Martin’s writings. With a sweeping body count and the killing of the much-feared Night King (Vladimir Furdik) by Arya Stark (Maisie Williams) in the final minutes, the much-anticipated episode is also the second most watched GoT ever, at least for now.

The long and bloody “The Long Night” snared 12.02 million viewers on April 28.

The draw of “The Long Night” is  just a mere 55,000 sets of eyeballs less than which tuned in for the all-time GoT viewership high of the Season 7 finale. That August 27, 2017, “The Dragon and The Wolf” episode drew 12.07 million linear viewers.

The 5.28 rating among adults 18-49 that “The Long Night” snagged is the second best demo result GoT has had. No surprise, the top 18-49 result, so far, remains that Season 7 ender. “The Dragon and The Wolf” roped in a 5.70 rating among the key demo.

Squarely the top non-season finale GoT so far among linear viewers, the overall numbers could see an interesting uptick once HBO releases HBOGo and HBO NOW figures later today.

Of course, with the battle for Winterfell literally the culmination of one of the major plots of the entire series, it will be very interesting to see how many fans actually went digital as opposed to watching the darkly filmed drama of warfare against the Army of the Dead in real time.

Turning back to linear viewership for a sec, the third episode of the final season of GoT rose 16.7% from Easter Sunday’s “A Knight of the Seven Kingdoms.” Season-to-season, “The Long Night” was up a kingslaying 30% in its audience from the July 30, 2017 “The Queen’s Justice” third episode of Season 7.

“The Long Night” was first episode of the eighth and last season of GoT to be penned by Benioff and Weiss this year

All written by the EPs, there are three more episodes of Game of Thrones left, with the series finale on May 19. Benioff and Weiss are directing that series ender, which we don’t yet know the title of.
