Cyclones surrounding Jupiter's poles are unlike anything else encountered in solar system

Cyclones surrounding Jupiter's poles are unlike anything else encountered in solar system

This picture of the Jupiter's South Pole is a mosaic of many images acquired by the Jovian InfraRed Auroral Mapper on board the Juno shuttle. Based on Juno's measurements, the scientists found out that hydrogen and helium gases make up the planet's core and beneath the layer of atmosphere, Jupiter rotates as a solid mass of ball.

"Juno's unique orbit and evolutionary high-precision radio science and infrared technologies enabled these paradigm-shifting discoveries", said Scott Bolton, principal investigator of Juno from the Southwest Research Institute, San Antonio, Texas, US.

The cyclonic winds Juno discovered extend deeper into the planet than any similar weather pattern on Earth - as far as 1,900 miles, or 3,000 kilometers, into Jupiter, constituting about 1% of its mass.

"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.

The "weather layer" of jupiter accounts for roughly one percent of the planet's total mass. The deeper the jets streams go, the more mass they contain, exerting a strong effect on Jupiter's gravitational field, Kaspi said.

These initial findings about Jupiter's jet streams and gravity field are basis for the deeper understanding of the planet's core and could answer other questions on deep planetary dynamics.

The huge cyclones at the poles are believed to be lasting atmospheric features, and are "unlike anything encountered in our solar system", the scientists say.

"They have very violent winds, reaching, in some cases, speeds as great as 220 miles per hour (350 kph)".

The fifth planet from our sun, gas giant Jupiter is by far the largest planet in our solar system.

While these storms might look like the same cyclone with branched arms, they are actually separate storms that are densely packed.

Even with all this information, we're still just barely scratching the surface of what we know about Jupiter. They also hope to understand, among other things, why this storm, which has been stable for as long as telescopes have existed, has been shrinking in recent years. "There is nothing else like it that we know of in the solar system", he added.

Last month, Nasa revealed that the great red spot over Jupiter, its defining feature, will most likely be gone in about a decade.

"Each one of the northern cyclones is nearly as wide as the distance between Naples, Italy and New York City - and the southern ones are even larger than that".

Getting that information, Guillot said, allowed them to get a handle on the depth of the flow. At the north pole, eight storms surrounded one storm at the center. "We tried to fit the Cassini data in the same way as Juno's data, but simply it did not work". On Feb. 7, Juno completed its 10th science orbit of Jupiter. Juno's 11th science pass will be on April 1.

When the Juno mission was successfully launched in 2011, astronomers worldwide were thrilled.

They are about as wide as the distance between Naples and NY, noted lead author of the research Alberto Adriani, Juno co-investigator from the Institute for Space Astrophysics and Planetology, Rome.
