NASA scientists have noticed an interesting phenomenon in the giant red spot of Jupiter. While the storm on the edge is accelerating steadily, on Wednesday, on the contrary, it is slowing down. Astronomers have no idea why this is happening.
While observing Jupiter with the Hubble Telescope, NASA found a strange change in its large red spot. The edge of the storm in the spot, which is about 15 thousand kilometers in diameter, is accelerating. On the contrary, the middle part of the storm slows down. Both parts, which are moving in the opposite direction, ie have changed speed in the last ten years, the scientists write in their own studied.
The outer part of the storm has been accelerating steadily for the last ten years or so. From 2009 to 2020, about 3.2 kilometers per hour each year. The center of the storm, on the other hand, slowed at a similar rate.
“No one has seen anything like this before,” said astronomer Michael Wong in the study. He worked with his colleague Amy Simon in the study.
Why this is happening and why the external storm is not slowing down, but Wong cannot explain yet. “It’s hard to tell because the telescope doesn’t see well from below. Things under the clouds are hard to see,” says Wong.
The wind at the edge of the storm blows at a speed of about 640 kilometers per hour. People have been watching the big spot for at least the last 150 years, from the moment they take good care of it. To date, scientists have not been able to explain its origin, origin, physical explanation and behavior.
