Jupiter's Great Red Spot (GRS)
In a staggering revelation, NASA’s Hubble Space Telescope detected Jupiter’s unbelievable Great Red Spot (GRS) shaking like a bowl of gelatin.
The GRS has consistently fascinated the space experts with its presence. It is an anticyclone in the planet which is huge enough that it can swallow Earth and is accepted to have been available for no less than 150 years.
However, in the new observations made by Hubble from the information gathered across 90 days between December 2023 to March 2024, it was found that GRS isn’t really stable.
The blend of the Hubble pictures helped astronomers with making a period pass film of the unexpected way of behaving of the GRS.
“While we knew its motion varies slightly in its longitude, we didn’t expect to see the size oscillate. As far as we know, it’s not been identified before,” said Amy Simon, lead author of the paper published in The Planetary Science Journal and member of NASA’s Goddard Space Flight Centre in Greenbelt, Maryland.

“This is actually whenever we’ve first had the proper imaging rhythm of the GRS. With Hubble’s high resolution, we can say that the GRS is conclusively squeezing in and out simultaneously as it moves quicker and more slow. That was exceptionally startling, and as of now, there are no hydrodynamic explanations,” he added.

The group, drove by Simon, utilized the Hubble telescope to focus in on the GRS and get nitty gritty data with respect to its size, shape, and any unpretentious variety changes.
“At the point when we look carefully, we see a ton of things are changing from one day to another,” Simon said.
In the review, bright light perceptions were made, which showed that the tempest’s particular center gets most brilliant when the GRS arrives at its biggest size in its swaying cycle. This is demonstrative of less dimness retention in the upper air.
“As it speeds up and decelerates, the GRS is pushing against the breezy fly streams toward its north and south,” expressed co-investigator Mike Wong of the University of California at Berkeley.
“It’s like a sandwich where the cuts of bread are compelled to swell out when there’s a lot filling in the center,” he added.
Since the OPAL program began a long time back, the group has been watching the GRS contract and has anticipated that it will keep contracting before it takes a steady, less-elongated, shape.
“This moment it’s over-filling its scope band comparative with the breeze field. When it contracts inside that band, the breezes will truly be holding it set up,” Simon said.
