We learn about our own weather through studying Jupiter so very important that we now know more. May even help with predicting hurricane season a bit better... that would be nice given where I'm situated as we are in a tropical weather climate.

Nasa reveals latest pictures of Jupiter, showing planet like nobody has ever seen before

Jupiter is covered in intense, massive storms far more complex than anyone had expected, Nasa has revealed.

The geometric clusters of cyclones that cover the planet's poles are just one of the various discoveries reported by scientists studying data sent back from Nasa's Juno spacecraft, which is circling the planet.

The team has seen the cyclones churning in Jupiter's deep atmosphere in far greater detail than ever before

One group uncovered a constellation of nine cyclones over Jupiter's north pole and six over the south pole. The wind speeds exceed Category 5 hurricane strength in places, reaching 220 mph (350 kph).

The massive storms haven't changed position much — or merged — since observations began.

Team leader Alberto Adriani of Italy's National Institute for Astrophysics in Rome was surprised to find such complex structures. Scientists thought they'd find something similar to the six-sided cloud system spinning over Saturn's north pole.

"We were wrong about it," he said via email.

Instead, they found an octagon-shaped grouping over the north pole, with eight cyclones surrounding one in the middle, and a pentagon-shaped batch over the south pole. Each cyclone measures several thousand miles (kilometers) across.

The fifth planet from our sun, gas giant Jupiter is by far the largest planet in our solar system. Launched in 2011, Juno has been orbiting Jupiter since 2016 and peering beneath the thick ammonia clouds. It's only the second spacecraft to circle the planet; Galileo did it from 1995 to 2003.

Another of the studies in this week's journal Nature finds that Jupiter's crisscrossing east-west jet streams actually penetrate thousands of miles (kilometers) beneath the visible cloud tops. Refined measurements of Jupiter's uneven gravity field enabled the Weizmann Institute of Science's Yohai Kaspi in Rehovot, Israel, and his colleagues to calculate the depth of the jet streams at about 3,000 kilometers, or 1,865 miles.

"The result is a surprise because this indicates that the atmosphere of Jupiter is massive and extends much deeper than we previously expected," Kaspi said in an email.

By better understanding these strong jet streams and the gravity field, Kaspi said scientists can better decipher the core of Jupiter. A similar situation may be occurring at other big gas planets like Saturn, where the atmosphere could be even deeper than Jupiter's, he said.

Jonathan Fortney of the University of California, Santa Cruz, who was not involved in the research, called the findings "extremely robust" and said they show "high-precision measurements of a planet's gravitational field can be used to answer questions of deep planetary dynamics."

Using similar techniques, Juno could help scientists determine the depth of Jupiter's Great Red Spot, a colossal swirling storm, Fortney said in a companion article in the journal.

NASA's Jet Propulsion Laboratory researchers Glenn Orton and Fachreddin Tabataba-Vakili, who both took part in the cyclone study, said all these new discoveries "show Jupiter from a new perspective" unseen before Juno.

"We cannot say how many mysteries are left to uncover," they wrote in an email. "We are already finding way more fascinating results than we ever expected!"

That is incredible. Love stuff like this will have a good read later.

[Barry.]

Looks hot.

[kirklancaster]

Fascinating Maru.

[Mystic Mock]

I'm loving reading up on planets at the moment.

Jupiter definitely looks really fascinating in that picture.

[hijaxers]

Wow that's an incredible picture.

Sounds a bit like Falkirk

to think that all the crap spewed out after the big bang coalesce through gravity into balls like Jupiter in the same way a dust ball forms under a bed or cupboard

shamazing

can not understand any of this - watching wrightstuff today and the only planet I can see is mercury.


going to climb the hill.

A little overcooked.

It's amazing when you think how very different from each other the planets close to us are and makes you even keener to know what else is out there.
