Hubble discovers a mysterious dark spot on Neptune, and it's getting bigger – BGR



The mighty Jupiter gets a lot of attention for its constantly shifting face, but it's not the only planet in our solar system with some serious personality. Neptune, the large frozen gas of methane and various other frigid gasses, is surprisingly active, and the Hubble Space Telescope just caught it doing something they had never seen before.

Astronomers have known for a long time that Neptune's surface occasionally becomes dotted with dark spots. These large discolorations in its atmosphere can be linked to high pressure areas, and they come and go over the course of several years, but nobody had ever seen one forming until now

In a new study published in Geophysical Research Letters scientists explain how they spotted one of Neptune's 'Great Dark Spots' growing. The team originally focused on cloud patterns that began shaping years ahead of the dark spot's formation, ultimately hinting that dark spots originated deep within the planet's atmosphere rather than on the surface where we eventually observed them

This is just the latest in what has been a steady stream of new developments regarding Neptune's atmosphere. Originally observed in 1

989 by NASA's Voyager 2 probe, the first dark spots on the planets that scientists discovered were completely vanished by the time Hubble launched half a decade later, leaving astronomers scratching their heads

Unsure of what to make of it, researchers began to observe Neptune more regularly, eventually spotting several more dark spots coming and going with regularity. Now, it seems, scientists have a better idea of ​​when and where one of the large vortexes will form, and this discovery may yield more information about how and why they will shape in the near future
