A big dark storm Neptune The first sighting two years ago suddenly changed directions, leaving experts without answers.
The storm was discovered in 2018 by the Hubble Space Telescope, which was observed in the northern hemisphere of the planet. In 2019, it could be seen moving towards the southern hemisphere of the planet, but by August 2020, unlike other dark spots seen on the ice sheet in the past, it began to move north again. Another small, dark spot was also spotted, which is believed to be part of a larger storm that broke into a separate storm.
“We’re excited about these observations because this little dark piece may be part of the process of disrupting dark space,” said Michael H. Schmidt of the University of California, Berkeley. Wong said Report. “This is a process that has never been noticed. We have seen some other dark spots disappear, they are gone, but we have never seen anything disruptive as predicted in computer simulations.”
NASA first flew Neptune in 1989 With Took pictures of the Voyager 2 spacecraft and two dark spots. Until 1994 it was observed by Hubble on a regular basis. Since then, the space telescope has seen the “Great Dark Spot” and other dark spots on the planet.
The dark storm in question is believed to be across 4,600 miles, the fourth observed on Neptune since 1993. Unlike hurricanes on Earth, which rotate in low pressure and in the opposite direction, these storms rotate clockwise and have high pressure systems. But when they move towards the equator, they are affected by the Coriolis effect, which weakens them and eventually disintegrates after what is called the “killing zone”. This particular storm is not.
“It was so exciting to watch this one act, it had to act, and then suddenly it stopped and swayed again,” Wong said. “It was amazing.”
Although the small storm was 3,900 miles across, Wang believed it was the result of a major storm devastation, but it was not, adding to the conspiracy as to what caused it.
“I don’t think another vortex is formed because it is smaller towards the equator,” the researcher explained. “So it’s within this volatile region. But we can not prove that the two are related. It remains an absolute mystery.”
In August, researchers Created Computer models suggesting two planets have been created “primarily” of a strange body of water.
In March 2019, NASA JBL scientists A mission was proposed It will explore Neptune’s largest moon, Triton, which, according to some theories, may have hidden an ocean beneath the surface.
