A recent X-class flare, which was split into two simultaneous explosions, launched a coronal mass ejection that smashed into Earth, triggering the most powerful disruption to our planet's magnetic field for more than six years.

The Spring equinox (March 19, 2024) signals the start of spring in the Northern Hemisphere, the beginning of autumn in the Southern Hemisphere, and a rare moment of "equal night" across the world.

The solar system's eight planets will never truly be in a straight line, but they can get close to it.

A new geological study suggests that Mars' gravitational field pulls the Earth closer to the sun over cycles lasting millions of years, warming our climate.

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.
