Recently, a new sharp image from the Hubble Space Telescope shows the giant Jupiter's wild evolving weather. The photos revealed both short- and long-term changes of the majestic big brother planet.
The photos and studies have shown the different formation of the storms as well as the changes in the Great Red Spot. It indicated that in the northern hemisphere, turbulent clouds could mean the formation of a new swirling storm, while down south, a long-lived storm just below. The studies also show that about half the size of the Great Red Spot seems to be slowly changing colour from white to red.
The Great Red Spot is the most famous of Jupiter's storms. It is enormous, rotating anticlockwise and known to be in progress for at least 350 years.
Scientists found that, in the last few decades, the Great Red Spot has been shrinking. Currently, the Great Red Spot measures 15,800 kilometres across, a decrease from 16,350 kilometres that was measured in 2017.
Another similar storm on Jupiter is known as the Oval BA, which is much younger that the Great Red Spot. Scientists stated that the Oval BA formed in the late 1990s from three smaller storms. The Oval BA, which started as a white storm, changed in 2006. Scientists noticed that it was changing colour and turning red like the Great Red, but the Oval BA did not stay red, and has changed back to its original colour. However, Hubble's new image reveals that the white colouration wasn't permanent either, as Oval BA seems to be turning back to red again.
Scientists find this and interesting study as they would like to determine what the reason behind the changing of the colour is, and if any pattern is attach to the changing.
The Hubble images also show that a very bright white storm, which is travelling at around 560 kilometres per hour, has formed in the northern hemisphere.
The images also show that small, dark cyclonic clumps, rotating in an anticlockwise direction are following behind the storm.
Scientists are eager further study the fascinating wild atmosphere of Jupiter.
