Saturn's moon Titan has lakes and seas, filled with liquid ethane and methane. But they might not be the best places to look for life, according to new research.

In space, dust comes from comets and exploding stars. It can form planetary rings, drive global weather patterns and even form the seeds of new planets.

Asteroid on a collision course with Earth? These astronomers will likely see it first. NASA's Center for Near-Earth Object Studies - now entering its 3rd decade - makes over 90 percent of near-Earth asteroid and comet discoveries. Here's how and why they do their work.

Jupiter's moon Europa is a promising place to search for evidence of alien life. New research provides insights on what might be the best - and easiest - way to search.

At first glance, it's just a square filled with tiny grains of static. But incredible as it is to imagine, every single point of light in this image is actually a distant galaxy, as observed by ESA’s Herschel Space Observatory.

“Mars wouldn’t be nearly this dusty if it wasn’t for this one enormous deposit that is gradually eroding over time and polluting the planet, essentially.”

ESA's Mars Express spacecraft has discovered the 1st evidence for a subsurface liquid lake on Mars. If it exists, this lake is likely salty and cold, but possibly habitable for some microorganisms.

Not now, but billions of years ago, microbes might have thrived in water pools on the moon until its surface became dead and dry.

It had been theorized that some young stars might devour their planets. Now astronomers have the 1st solid evidence - from the Chandra X-ray Observatory - of just such an event caught in the act.

Two billion years ago, the Andromeda galaxy - closest large spiral galaxy to our Milky Way - might have eaten another large galaxy.
