Video: 'Hot spots' ride a merry-go-round on Jupiter
In the swirling canopy of Jupiter's atmosphere, cloudless patches are so exceptional that the big ones get the special name "hot spots." Exactly how these clearings form and why they're only found near the planet's equator have long been mysteries. Now, using images from NASA's Cassini spacecraft, scientists have found new evidence that hot spots in Jupiter's atmosphere are created by a Rossby wave, a pattern also seen in Earth's atmosphere and oceans. The team found the wave responsible for the hot spots glides up and down through layers of the atmosphere like a carousel horse on a merry-go-round.
"This is the first time anybody has closely tracked the shape of multiple hot spots over a period of time, which is the best way to appreciate the dynamic nature of these features," said the study's lead author, David Choi, a NASA Postdoctoral Fellow working at NASA's Goddard Space Flight Center in Greenbelt, Md. The paper is published online in the April issue of the journal Icarus.
Choi and his colleagues made time-lapse movies from hundreds of observations taken by Cassini during its flyby of Jupiter in late 2000, when the spacecraft made its closest approach to the planet. The movies zoom in on a line of hot spots between one of Jupiter's dark belts and bright white zones, roughly 7 degrees north of the equator. Covering about two months (in Earth time), the study examines the daily and weekly changes in the sizes and shapes of the hot spots, each of which covers more area than North America, on average.
Much of what scientists know about hot spots came from NASA's Galileo mission, which released an atmospheric probe that descended into a hot spot in 1995. This was the first, and so far only, in-situ investigation of Jupiter's atmosphere.
"Galileo's probe data and a handful of orbiter images hinted at the complex winds swirling around and through these hot spots, and raised questions about whether they fundamentally were waves, cyclones or something in between," said Ashwin Vasavada, a paper co-author who is based at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and who was a member of the Cassini imaging team during the Jupiter flyby. "Cassini's fantastic movies now show the entire life cycle and evolution of hot spots in great detail."
Because hot spots are breaks in the clouds, they provide windows into a normally unseen layer of Jupiter's atmosphere, possibly all the way down to the level where water clouds can form. In pictures, hot spots appear shadowy, but because the deeper layers are warmer, hot spots are very bright at the infrared wavelengths where heat is sensed; in fact, this is how they got their name.
One hypothesis is that hot spots occur when big drafts of air sink in the atmosphere and get heated or dried out in the process. But the surprising regularity of hot spots has led some researchers to suspect there is an atmospheric wave involved. Typically, eight to 10 hot spots line up, roughly evenly spaced, with dense white plumes of cloud in between. This pattern could be explained by a wave that pushes cold air down, breaking up any clouds, and then carries warm air up, causing the heavy cloud cover seen in the plumes. Computer modeling has strengthened this line of reasoning.
From the Cassini movies, the researchers mapped the winds in and around each hot spot and plume, and examined interactions with vortices that pass by, in addition to wind gyres, or spiraling vortices, that merge with the hot spots. To separate these motions from the jet stream in which the hot spots reside, the scientists also tracked the movements of small "scooter" clouds, similar to cirrus clouds on Earth. This provided what may be the first direct measurement of the true wind speed of the jet stream, which was clocked at about 300 to 450 mph (500 to 720 kilometers per hour) -- much faster than anyone previously thought. The hot spots amble at the more leisurely pace of about 225 mph (362 kilometers per hour).By teasing out these individual movements, the researchers saw that the motions of the hot spots fit the pattern of a Rossby wave in the atmosphere. On Earth, Rossby waves play a major role in weather. For example, when a blast of frigid Arctic air suddenly dips down and freezes Florida's crops, a Rossby wave is interacting with the polar jet stream and sending it off its typical course. The wave travels around our planet but periodically wanders north and south as it goes.
The wave responsible for the hot spots also circles the planet west to east, but instead of wandering north and south, it glides up and down in the atmosphere. The researchers estimate this wave may rise and fall 15 to 30 miles (24 to 50 kilometers) in altitude.
The new findings should help researchers understand how well the observations returned by the Galileo probe extend to the rest of Jupiter's atmosphere. "And that is another step in answering more of the questions that still surround hot spots on Jupiter," said Choi.

Vatican rejects 'dirty war' accusations against pope
Reports that the leader of Argentina's Jesuits didn't do enough to protect two priests kidnapped and tortured during Argentina's military dictatorship are believed to be anti-clerical elements used to attack the church, according to the Vatican. NBC's Anne Thompson reports.
By Ian Johnston, Staff Writer, NBC News
The Vatican on Friday denied ?anti-clerical? accusations that Pope Francis failed to protect priests during the so-called ?dirty war? waged by Argentinian dictators more than 30 years ago.
?We have every reason to affirm that these accusations are not reliable and there is no reason for them today to cast a shadow over the new pope,? Vatican spokesman Father Federico Lombardi said at a briefing.
A second spokesman, Father Tom Rosica said the accusations by a Argentinian journalist amounted to a political smear campaign against the new pope, who was known as Cardinal Jorge Bergoglio until his election on Wednesday.
?They reveal left-wing elements, anti-clerical elements that are used to attack the Church,? Rosica said. ?They must be firmly and clearly denied.?
Bergoglio was not a cardinal, or even a bishop, during the time in question but supervisor of Jesuit priests in Argentina.
Two Jesuits were kidnapped in 1976 by government agents. Although Bergoglio has said he quietly pushed for their release, he has been dogged by criticism he didn?t do enough to stand up to the military junta or speak out against human-rights abuses.
The Vatican?s strong defense of Pope Francis came as he met an audience of cardinals, urging them never to give in to the ?bitterness? that ?the devil places before us every day.?
During a meeting in the Sistine Chapel, Francis stumbled on the steps to his throne but managed not to fall and quickly smiled.
Among the challenges faced by the church are allegations of corruption with the Vatican and the ongoing scandal over sex abuse of children by priests.
Francis may have had those problems in mind when he urged some 150 assembled cardinals to remain hopeful and to keep trying to do the right thing.
Argentines divided on pope's legacy
"Let us never give in to the pessimism, to that bitterness, that the devil places before us every day. Let us not give into pessimism and discouragement," he said, according to Reuters.
The 76-year-old pontiff also said that the church?s elder statesman should help the younger generation of clergy.
After distancing himself from the traditional pomp and privilege of his new title, Pope Francis ? known for his sincerity and frugality ? has shown every indication that he plans to remain an educator and a pastor in addition to all of his other responsibilities. NBC's Anne Thompson reports.
"We are in old age. Old age is the seat of wisdom," he said, according to Reuters. "Like good wine that becomes better with age, let us pass on to young people the wisdom of life."
Francis also paid tribute to Emeritus Pope Benedict, who decided to stand down last month.
Benedict had "lit a flame in the depths of our hearts that will continue to burn because it is fueled by his prayers that will support the church on its missionary path,? Francis said, according to The Associated Press.
"In these years of his pontificate, he enriched and invigorated the church with his magisterium, his goodness, guide and faith ? his humility and his gentleness,? he added.
Francis has brought to the papacy a new tone of informality -- some of his remarks Friday were said to be unscripted and he spoke from the pulpit, not the throne -- and an ordinary touch.
He was pictured paying his own hotel bill, and in Argentina people told of how he used to regularly ride the bus as a cardinal. He has been dubbed the "slum pope" because of his work in poor areas of his home country.
Cardinal Sean O'Malley, archbishop of Boston, said that Francis "coming out of Latin America is very much impassioned by a desire to make the church present to people in suffering."
Reuters and The Associated Press contributed to this report.

LOS ANGELES (AP) ? What a difference four years have made.
When the cast of "The Big Bang Theory" first appeared at PaleyFest in 2009, their sitcom wasn't even among the top-40 rated shows in the United States.
Last week's first-run "Big Bang" episode topped the list in viewers most coveted by advertisers, those ages 18-49; and it was the second most-watched show overall (behind "NCIS") with more than 20 million viewers.
What made "Bang" so much bigger? Credit syndication. Reruns of the show have been almost impossible to avoid since local stations and cable network TBS debuted them in September 2011 ? introducing the series and hooking millions of viewers who didn't catch episodes the first times around on CBS.
"You're kind of forced to watch the show now," joked actor Simon Helberg, one of the show's stars, Wednesday night on the PaleyFest arrivals line. "We're shoving it down people's throats, and then they're learning that they love that."
From co-creators Chuck Lorre and Bill Prady ("Dharma & Greg"), "The Big Bang Theory" spins around two roommates, physicists Leonard Hofstadter (played by Johnny Galecki) and Sheldon Cooper (Jim Parson), as well as their friends and colleagues, engineer Howard Wolowitz (Simon Helberg) and astrophysicist Raj Koothrappali (Kunal Nayyar).
Parsons may play a genius, but he's having a tough time getting his head around the show's current success.
"There's something impossible to fathom about viewers and numbers and things like that," Parsons explained. "I can barely picture 20 people in one room. If you want to say 17 or 18 million, well you've lost me."
The "Big Bang" cast and crew were careful to withhold any major upcoming plot developments, except for one ? to be revealed in the first-run episode airing Thursday night: the discovery of a letter from Howard's long-lost father. "They (Howard and his scientist wife Bernadette) find the letter," revealed actress Melissa Rauch, who plays Bernadette. "Or someone finds the letter," Rauch added, coyly.
No other cast members or co-creator Lorre would go near discussions of the characters' futures. But Helberg did agree to dream up a season-20 endgame for the "Big Bang" bunch.
"Well I think (Howard's) pants will probably be as skinny and probably a bit tighter," Helberg began. "I think that Sheldon will probably still be sitting in his spot. It may be in a different apartment. I think he'll sit in that spot until he's in a home. Howard and Bernadette probably will ... God, God help them if they have children. We know she hates them and we know that Howard, essentially, is a child. So I wish them luck."
PaleyFest, an annual open-to-the-public series of TV-series cast and crew panel discussions, runs through Friday at the Saban Theatre in Los Angeles.
