The tiny space rock was likely flung off the Moon's surface after a massive impact not too long ago.
The end of the Cretaceous period saw disastrous geological and astronomical events, but researchers say that one in particular is to blame for the mass extinction.
The spunky Lucy mission will make a second gravity assist of our world tonight as it heads off on its hunt for the solar system's origins.
They look like asteroids, but act like comets.
A chunk of rock collected from the asteroid Ryugu contains bacteria—but, unfortunately, it's not evidence of alien life.
A new study posits that our planet's gravity will cause seismic activity on Apophis when it makes its close approach in 2029.
No need to freak out—only one asteroid is big enough to be considered hazardous, and it’s staying millions of miles away.
The 5.3-mile-wide crater is now confirmed to be 66 million years old, suggesting that the impact of at least two giant space rocks preceded the mass extinction of dinosaurs.
Nuclear devices generate massive amounts of X-rays. A new experiment suggests that might be enough to divert a killer asteroid.
A weird number of craters are located close to the equator, and the odds that this is random are incredibly low, researchers say.
The tiny asteroid will complete a wide orbit over the course of 53 days, but don't get your hopes up about seeing it.
The impact event happened 4 billion years ago and can be further investigated by an upcoming mission.
Rocks knocked off Dimorphos could come back to bite us in a few years—in the form of harmless meteors.
When the Chicxulub asteroid slammed into Earth, it set off a chain of planet-wide devastation. New research suggests we should blame Jupiter.
The satellite played an integral role in laying the groundwork for NASA's planetary defense mission.
The mysterious objects may be far more common than we thought and may have brought water to Earth.
The tiny asteroid was left deformed after the spacecraft slammed into it at a high rate of speed.
Armed with this promising new tool, a cutting-edge observatory in Chile will sweep the cosmos for all sorts of transient objects.
