NASA's Chandra X-ray Observatory has captured a massive cloud of multimillion-degree gas that scientist believe was likely caused by a collision between a dwarf galaxy and a much larger spiral galaxy.

These 12 near-Earth asteroids could be mined for precious metals and other raw materials.

The Perseid meteor shower is at its peak, giving stargazers a chance to view hundreds of meteors.

The shower’s peak begins Sunday. You can catch a live stream of the phenomenon starting at 4 p.m. PDT (7 p.m. EDT).

The Perseid meteor shower peaks on Monday, but the viewing party can start tonight. Here are some tips on the summer's prime skywatching event.
