China's first Mars rover has captured its first sounds of the Red Planet and beamed back stunning views of a drive on the dusty world.
Astronomers have found evidence of a rare electron-capture supernova for the first time, which could help solve a 1,000-year-old space mystery.
Much more liquid water may lie beneath Mars' south pole than scientists had thought — or there may be something going on down there that they don't fully understand.
The researchers hope to use their apparatus to probe why large objects do not exhibit quantum effects.
An enormous, ghostly hand stretches through the depths of space, its wispy fingers pressing against a glowing cloud. It sounds like something out of sci-fi, but it's quite real.
Our planet is constantly moving, racing around the sun and spinning on its axis. But how fast does it move?
