New Hubble images reveal what happened to one of Jupiter’s main cloud belts: It’s hiding behind ammonia clouds. “Weather forecast for Jupiter’s Southern Equatorial Belt: cloudy with a chance of ammonia,” planetary scientist Heidi Hammel of the Space Science Institute in Boulder, Colorado said in a press release Wednesday. The gas giant’s characteristic band of dark clouds started fading... 

The X marks the spot of a suspected head-on collision between two asteroids imaged by the Hubble Space Telescope’s new-and-improved Wide Field Camera. If it’s confirmed by further observations, it would be the first time that scientists have detected the interplanetary collision between objects in the asteroid belt, though they believe that such occurrences are common. The complex structure of... 

The Hubble Space Telescope captured this spectacular space fireworks display when a blob of matter within a 5,000-light-year-long plasma beam emanating from a giant black hole flared up. The glowing clump of gas, first discovered in 1999 and named HST-1, is located in one of the most massive black holes ever discovered, in the giant elliptical galaxy M87 54 million light years away from Earth. It...
