NASA’s Hubble Space Telescope has been closely observing Jupiter’s Great Red Spot, a gas giant’s famous storm, and has found out that it behaves like a stress ball. It has been noticed that the storm expands and contracts in size, similar to the action of squeezing and releasing a stress ball. The Great Red Spot is a long-lived storm, more significant than the Earth, that has been raging in Jupiter’s atmosphere for at least 150 years.
Hubble’s observations have revealed that the storm is not just changing in size but also in shape. At times, it takes an oval form, while at other instances, it appears circular. The changes are primarily driven by the storm’s winds, which can reach speeds of up to 400 miles per hour.
In 2019, amateur astronomers noticed a strange phenomenon where large flakes or chunks appearing to peel away from the storm. This incident was considered unusual as it had not been observed before. However, despite the occasional shedding, the storm has maintained its overall size and intensity.
Scientists believe that the changes in the Great Red Spot’s size and shape might be related to the storm’s interaction with the jet streams surrounding it. This is similar to the way changes in hurricanes on Earth can be affected by surrounding winds. Another theory suggests that the storm might be influenced by an inflow of cooler gases from the poles and an outflow of warmer gases towards the equator.
Hubble’s continuous monitoring of the storm is providing invaluable insights into Jupiter’s complex atmosphere. The data from Hubble is combined with that from the Juno spacecraft, which is currently orbiting Jupiter, to create a comprehensive picture of the gas giant.
The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. Hubble’s science operations are conducted at the Space Telescope Science Institute in Baltimore, Maryland.
Knowing more about Jupiter’s atmosphere and the storms that rage within it can help scientists understand more about our solar system’s history and formation. It can also provide crucial insights into the dynamics of weather systems on other planets and aid in the interpretation of data from future missions to other gas giants in our solar system.
