Now, for the first time, we have observed a Neptune Storm with Earth-based instruments in unprecedented resolution.
Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.
It is the sixth storm scientists have been able to document since 1989 when NASA's Voyager 2 probe first flew past Neptune, but it is the first whose birth and development was documented.
