NASA releases never-before-seen photos of Jupiter's stormy poles

CAPE CANAVERAL: Monstrous cyclones are churning over Jupiter's poles, until now a largely unexplored region that is more turbulent than scientists expected.
NASA's Juno spacecraft spotted the chaotic weather at the top and bottom of Jupiter once it began skimming the cloud tops last year, surprising researchers who assumed the giant gas planet would be relatively boring and uniform down low.
"What we're finding is anything but that is the truth. It's very different, very complex," Juno's chief scientist Scott Bolton of the Southwest Research Institute said Thursday.
With dozens of cyclones hundreds of miles across — alongside unidentifiable weather systems stretching thousands of miles — the poles look nothing like Jupiter's equatorial region, instantly recognizable by its stripes and Great Red Spot, a raging hurricane-like storm.
"That's the Jupiter we've all known and grown to love," Bolton said. "And when you look from the pole, it looks totally different ... I don't think anybody would have guessed this is Jupiter."
He calls these first major findings — published Thursday — "Earth-shattering. Or should I say, Jupiter-shattering."
Turning counter-clockwise in the northern hemisphere just like on Earth, the cyclones are clearly clustered near the poles. The diameters of some of these confirmed cyclones stretch up to 1,700 miles (2,800 kilometers). Even bigger, though shapeless weather systems are present in both polar regions. At the same time, the two poles don't really resemble each other, which is puzzling, according to Bolton.
Scientists are eager to see, over time, whether these super cyclones are stable or dynamic. "Are they going to stay the same way for years and years like the Great Red Spot ... Of course, only time will tell," Bolton said.
Just as intriguing will be how fast these super cyclones are moving.
Launched in 2011 and orbiting Jupiter since last summer, Juno is providing the best close-up views ever of our solar system's largest planet, peering beneath the clouds for a true portrait. It's made five close passes over Jupiter so far for science collection, the most recent last week; they occur about every two months given Juno's extremely oblong orbit. The next one will be in July, with investigators targeting the Great Red Spot.
Juno is moving so fast during these chummy encounters that it takes only two hours to get from the north pole to the south.
Besides polar cyclones, Juno has spotted white ice caps on Jupiter — frozen bits of ammonia and water. Bolton refers to them as Jovian snowfall — or maybe hail.
Juno also has detected an overwhelming abundance of ammonia deep down in Jupiter's atmosphere, and a surprisingly strong magnetic field in places — roughly 10 times greater than Earth's. It's also led scientists to believe Jupiter may have a "fuzzy" core — as Bolton puts it — big but partially dissolved.
Then there are the eerie sounds of plasma waves at Jupiter — "nature's music," according to Bolton. During the teleconference, he played two minutes of the spacecraft's recording from February, adjusted for the human ear and full of percussion sounds as well as high-pitched beeps and squeals, and even flute-like notes.
Results were published in Science and Geophysical Research Letters.
Jupiter's poles appear dramatically different from neighboring Saturn's, according to the scientists, with nothing like the hexagon-shaped cloud system over Saturn's north pole.
Researchers hope to compare Juno's observations with those of NASA's Cassini spacecraft, in its final months orbiting Saturn.
Juno's findings are "really going to force us to rethink not only how Jupiter works, but how do we explore Saturn, Uranus and Neptune," Bolton said.

How Netflix won Hollywood’s biggest prize, Warner Bros Discovery

  • Board rejected Paramount’s $30 a share bid amid funding concerns, sources say
  • Warner Bros board met daily before accepting Netflix’s binding offer

LOS ANGELES/NEW YORK: What started as a fact-finding mission for Netflix culminated in one of the biggest media deals in the last decade and one that stands to reshape the global entertainment business landscape, people with direct knowledge of the deal told Reuters. Netflix announced on Friday it had reached a deal to buy Warner Bros Discovery’s TV, film studios and streaming division for $72 billion. Although Netflix had publicly downplayed speculation about buying a major Hollywood studio as recently as October, the streaming pioneer threw its hat in the ring when Warner Bros Discovery kicked off an auction on October 21, after rejecting a trio of unsolicited offers from Paramount Skydance .
Details of Netflix’s plan and the Warner Bros board’s deliberations, based on interviews with seven advisers and executives, are reported here for the first time.
Initially motivated by curiosity about its business, Netflix executives quickly recognized the opportunity presented by Warner Bros, beyond the ability to offer the century-old studio’s deep catalog of movies and television shows to Netflix subscribers. Library titles are valuable to streaming services as these movies and shows can account for 80 percent of viewing, according to one person familiar with the business.
Warner Bros’ business units — particularly its theatrical distribution and promotion unit and its studio — were complementary to Netflix. The HBO Max streaming service also would benefit from insights learned years ago by streaming leader Netflix that would accelerate HBO’s growth, according to one person familiar with the situation. Netflix began flirting with the idea of acquiring the studio and streaming assets, another source familiar with the process told Reuters, after WBD announced plans in June to split into two publicly traded companies, separating its fading but cash-generating cable television networks from the legendary Warner Bros studios, HBO and the HBO Max streaming service.
Netflix and Warner Bros did not reply to requests for comment.
The work intensified this autumn, as Netflix began vying for the assets against Paramount and NBCUniversal’s parent company, Comcast.
Warner Bros kicked off the public auction in October, after Paramount submitted the first of three escalating offers for the media company in September. Sources familiar with the offer said Paramount aimed to pre-empt the planned separation because the split would undercut its ability to combine the traditional television networks businesses and increase the risk of being outbid for the studio by the likes of Netflix.
Around that time, banker JPMorgan Chase & Co. was advising Warner Bros Discovery CEO David Zaslav to consider reversing the order of the planned spin, shedding the Discovery Global unit comprising the company’s cable television assets first. This would give the company more flexibility, including the option to sell the studio, streaming and content assets, which advisers believed would draw strong interest, according to sources familiar with the matter.
Executives for the streaming service and its advisory team, which included the investment banks Moelis & Company, Wells Fargo and the law firm Skadden, Arps, Slate, Meagher & Flom, had been holding daily morning calls for the past two months, sources said. The group worked throughout Thanksgiving week — including multiple calls on Thanksgiving Day — to prepare a bid by the December 1 deadline.
Warner Bros’ board similarly convened every day for the last eight days leading up to the decision on Thursday, when Netflix presented the final offer that sources described as the only offer they considered binding and complete, sources familiar with the deliberations said.
The board favored Netflix’s deal, which would yield more immediate benefits over one by Comcast. The NBCUniversal parent proposed merging its entertainment division with Warner Bros Discovery, creating a much larger unit that would rival Walt Disney. But it would have taken years to execute, the sources said.
Comcast declined to comment.
Although Paramount raised its offer to $30 per share on Thursday for the entire company, for an equity value of $78 billion, according to sources familiar with the deal, the Warner Bros board had concerns about the financing, other sources said.
Paramount declined comment.
To reassure the seller over what is expected to be a significant regulatory review, Netflix put forward one of the largest breakup fees in M&A history of $5.8 billion, a sign of its belief it would win regulatory approval, the sources said. “No one lights $6 billion on fire without that conviction,” one of the sources said.
Until the moment late on Thursday night when Netflix learned its offer had been accepted — news that was greeted by clapping and cheering on a group call — one Netflix executive confided that they thought they had only a 50-50 chance.
