In 2021, a solar storm was recorded by multiple different spacecraft and the results tell quite the story.

Passing stars may have altered Earth's orbit, and its climate, many times throughout cosmic history. New research digs into what that means when it comes to understanding our planet's past.

Scientists say they're growing "organoids" in space to better understand cancer, neurological diseases and aging, and to hopefully uncover treatments.

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.

Earth moves around the sun at 67,000 mph and makes a full rotation once every 24 hours. So why can't we feel the Earth's rotation?

A "potentially hazardous" space rock the size of a football stadium is about to reach its closest point to our planet for more than 100 years, and it won't get this close to us again for centuries more.

Asteroid 2024 BJ, which astronomers detected earlier this month, will zoom within 220,000 miles of Earth tomorrow, or closer to us than the average distance to the moon.

Watch the Bulletin of the Atomic Scientists' annual Doomsday Clock announcement to find out if 2024 is the year we creep closer than ever to a human-made apocalypse.

It may initially seem like a simple question, but determining which planet is closest to Earth is surprisingly tricky and can have multiple correct answers.

Scientists have identified three definitive supercontinents in Earth's history and predict the landmasses we live on today will come together again in the future.
