A chance discovery by a NASA rover on Mars shows that the red planet has a form of lightning, which researchers had suspected for decades but never seen.

Mars’s Coloe Fossae reveals a landscape shaped by ancient ice ages, with deep valleys, cratered terrain, and frozen debris flows preserved from a time when the planet’s climate dramatically shifted.

NASA has drafted its Mars rover Perseverance to help monitor the sun’s activity. Every day for the next two months, the rover will image the sun with its Mastcam-Z cameras, capturing crucial information about sunspots and other large features that can give clues to solar activity.

In recent decades, the red planet has gone from being a distant object of study to becoming the main target of human expansion beyond Earth—and the moon, of

On November 26, 2011, the NASA Curiosity rover launched to Mars. Curiosity was the biggest and most powerful rover anyone had ever sent to the Red Planet. The two-ton science laboratory is about the size of a small SUV.

In the fall of 1659, Christiaan Huygens observed the opposition of Mars, drawing what he saw.
