NASA "monitors the birth of the" Big Black Point "on the blue planet

NASA's Hubble Space Telescope captured for the first time a remarkable image of the Great Dark Spot on Neptune.

This place is quite similar to the big red Jupiter, a storm formed in high pressure areas.

These storms gather at Neptune every four to six years and each storm lasts about six years.

NASA's Voyager 2 spacecraft spotted the first big black spot on Neptune in 1989, but when the Hubble Space Telescope returned to the planet five years later, the storm was gone.

"It was certainly a surprise," said Amy Simon, who led the study. "We used to look at the big red dot of Jupiter, which was supposed to be there for over 100 years."

The new study revealed how the "big black dot" was different from the "big red dot" from Neptune to Jupiter.

The famous storm of Jupiter has been observed since at least 1830, thanks to jet currents that prevent the breaking of the big red spot.

But the winds on Neptune operate in much wider ranges, meaning that storms such as the "Great Dark Spot" usually hover at higher altitudes before disintegrating.

NASA is now hoping to study the changes in vortex shape and wind speed in the "Great Dark Spot".

"We have never measured the wind directly in Neptune's dark vortex, but we estimate its speed in the storm at 100 meters per second, which is quite similar to the speed of the wind in the great storm of Jupiter." said co-author Michael Wong.
