Asteroids passing Earth.

NASA has an office dealing with asteroids that might hit Earth. But we still might not be ready.

The idea is to be able to divert an asteroid that might come too close to comfort — as well as to learn more about the universe around us.

Vulcan

Why the long-lost planet Vulcan holds lessons for Planet Nine

Scientists used to believe there was a planet in our solar system called Vulcan — and we're not talking about Star Trek. But that's no longer the case.

A frame from a simulation of the merger of two black holes and the resulting emission of gravitational radiation (colored fields, which represent a component of the curvature of space-time). The yellow areas near the black holes do not correspond to physi

Listen to the collision of two black holes. Einstein was right.

One hundred years ago, Einstein predicted the existence of gravitational waves. Today, for the first time, scientists announced that they've actually been detected. Here's what the discovery might mean for our understanding of the universe.

How a mislaunched satellite might help us test Einstein's theory of general relativity

Two satellites accidentally launched into the wrong orbit may help researchers test an aspect of Einstein's theory of general relativity.

What does Pluto look like? Imagine three-mile-high mountains and nitrogen glaciers.

We now have high-resolution photos of alien landscapes on the outer reaches of our solar system, and scientists are pretty excited about what those images reveal.

Kepler

Did the Kepler telescope just find the first signs of alien life?

​The Kepler telescope picked up a “swarm” of movement near Star KIC 8462852. Some scientists are exploring whether or not this might be evidence of alien life.
