No need to worry, everything is fine! It’s just that a mysterious dark vortex has opened up in the skies over Neptune. Hubble just snagged a picture of a dark vortex looming over Neptune during a May 16th view of the planet. This is actually the third documented sighting of a dark vortex in Neptune’s atmosphere. It was seen in 1989, during a Voyager fly-by. Then, in 1994, Hubble spotted the strange feature again. Dark vortices form when clouds of gas and air in Neptune’s atmosphere begin swirling and eventually freeze up in the icy temperatures, to move as a single strange mass.
