Astronomers have discovered that the magnetar SGR 0501+4516 is speeding through our galaxy at more than 110,000 mph. This unusually fast speed hints that it was not born as expected, which could help explain the puzzling origin of some fast radio bursts.

NASA's Perseverance rover on Mars has discovered unusual "float" rocks on the rim of Jezero Crater while searching for signs of ancient microbial life. Scientists are investigating their origin.

Is it possible to build a Dyson sphere that isn't catastrophically unstable? New research says yes, but only in one type of star system.

Researchers bombarded lichens with a year's worth of Martian radiation in just 5 hours — and they survived, hinting that the extremophiles could potentially live on the Red Planet.

Early on April 24, Venus will be at its brightest in the morning sky — just 67 days after it was at its brightest in the evening sky. Here's why.

The James Webb Space Telescope has pointed its infrared optics at the 'Crystal Ball Nebula' NGC 1514, a planetary nebula studied since the late 1800s.

NASA's Curiosity Rover has discovered long carbon chains on Mars. On Earth, molecules like these are overwhelmingly produced by biological processes.

A slowly spinning universe could resolve a puzzle in physics known as the Hubble tension, a new model suggests.

Researchers conducted the first-ever near-infrared analysis of an extragalactic recurrent nova and found it is one of the hottest nova explosions ever discovered.
