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.

NASA has successfully transmitted data between Earth and two spacecraft using lasers, completing a groundbreaking experiment that could aid in future missions to other worlds.

Researchers are developing a real-life tractor beam, with the goal of pulling defunct satellites out of geostationary orbit to alleviate the space junk problem.

A research plane that flew through Earth's stratosphere identified more than 20 elements that are linked to the aerospace industry. Experts predict that the problem could become much worse in the future.

The NOAA satellites GOES-East and GOES-West watched as the shadow of the moon darkened the surface of Earth on Saturday, Oct. 14.

New research finds that SpaceX's Starlink satellites are leaking radiation that could interfere with radio astronomy.

The sun is quickly approaching a major peak in solar activity. Experts warn it could potentially begin by the end of 2023, years before initial predictions suggested.

The atmospheric temperature spike, which was caused by geomagnetic storms triggered by the sun, suggests the "solar maximum" is fast approaching.

The mysterious Planet Nine may have up to 20 moons that could be superheated by the hypothetical planet's gravitational pull, making them easy to spot.

On a recent expedition to Antarctica, researchers discovered five perfectly-preserved meteorites that have likely been hiding beneath the ice for thousands of years.
