MIT researcher Richard Binzel has studied near-Earth asteroids for more than five decades and believes they could one day act as "space filling stations."

When a satellite runs out of fuel, it becomes little more than space junk. Now, space agencies and private companies want to change that. Here's how scientists plan to refuel satellites — in orbit.

Due to their proximity to Earth, minimoons are prime candidates for exploration. Now, some scientists want to use these tiny satellites to push humanity further into the cosmos.

There's nothing faster than the speed of light. So, what would happen if a human managed to move at this universal speed limit?

An X-class flare, the most powerful type of solar flare, erupted from the sun on Feb. 9, 2024. Lucky for us, Earth wasn't in the direct firing line.

The uncontrolled reentry of Europe's defunct ERS-2 satellite is expected in mid-February. It's highly likely that the 5,000-pound craft will land somewhere in the ocean.

Forty years ago this week, the first untethered spacewalk resulted in one of space exploration's most iconic images.

A group of sunspots measuring more than 15 times the diameter of Earth was imaged by NASA's Perseverance Rover last week; now, the spots are pointed toward Earth, with strong flares possible.

A new study of Saturn's 'Death Star' moon Mimas finds evidence of a young, underground ocean that may be hospitable to early forms of life.

Scientists are working hard to analyze samples of the potentially hazardous asteroid Bennu, with early results suggesting it may even be a chunk of an ancient water world.
