Mars

Here's how to watch the Red Planet swoop across the Beehive Cluster — one of the closest star clusters to Earth — after sunset this week.

The rover spotted a tiny Martian rock that looks eerily like a fossilized book on the surface of the Red Planet.

Data from China's unresponsive Zhurong rover suggests that Mars had snow and frost as recently as 400,000 years ago.

A satellite from the United Arab Emirates revealed that Mars' moon Deimos is made of the same material as the Red Planet itself, hinting at an ancient collision.

The rover has finally lost a pesky rock that had become lodged in its front left wheel "like a pebble in its shoe." The stone had accompanied the rover for more than half its time on the Red Planet.

A high-resolution camera mounted on NASA's Mars Reconnaissance Orbiter has snapped pictures of unusual, almost perfectly circular sand dunes on the Red Planet's surface.

The rays appear when sunlight shines through gaps in the cloud during sunrise or sunset and have never been seen this clearly on the Red Planet before.

The Mars rover Zhurong hasn't moved since last fall, new orbiter images confirm, suggesting that the Chinese rover may be at the end of its lifespan.

Research in Chile's Atacama Desert suggests that the science instruments on the Red Planet aren't capable of detecting signs of long-dead microbial life.

NASA's Curiosity Mars rover has photographed clear signs of ripples locked into a Martian rock, a sign of an ancient lake on the Red Planet's surface.
