This asteroid between Mars and Jupiter is actually two space rocks in one.

Black holes are invisible, so measuring them can be a difficult task. Scientists have found a shortcut for weighing the space voids.

A team of scientists has detected water ice on Mercury and they say there might be a ton more hiding on the scorching hot surface, waiting to be found.

Before we can start mining asteroids for their resources, we’ll have to learn a lot more about these mysterious space rocks.

Scientists have hunted down the magma feeding a powerful volcano in southern Italy that might explode just a few miles away from the site where Mount Vesuvius erupted and destroyed Pompeii.

Scientists saw a star that is almost rotating fast enough to break up into pieces, and it was emitting light in a special way one astrophysicist predicted decades ago.

A meteorite that crashed down to Earth 38 million years ago produced the hottest temperature scientists have ever found on our planet.

The clouds on the dark side of Venus are really weird-looking and move unpredictably.

A marine creature shaped like a bathmat has been a mystery for decades, but scientists may have finally figured out what it is.

An exoplanet is darker than asphalt because it’s so hot, making it a unique world for scientists to explore.

After almost 20 years of service, NASA’s Cassini spacecraft is about to take one last dive for science — a fatal one.

Peacock spiders are known for their funny courtship dances, and now scientists have seen two more.

An exoplanet the size of Jupiter is so hardcore that it has an atmosphere of titanium. Rock on, WASP-19b.

A 20-foot-long crocodile was a dominant predator in Texas 95 million years ago, when there was a sea in the middle of the United States.
