Mars doesn't have an organized planetary magnetic field like Earth, so auroras can appear anywhere in the sky. Now there's a photo of one.

Scientists directed NASA’s Perseverance rover to take an image of the Martian sky after a solar storm in hopes that an aurora ...

On Earth, they ripple across high-latitude skies in vibrant sheets of green, red, and violet. But with no global magnetic field to shape them, Mars experiences more chaotic, shattered auroral ...

But for now, the team is mostly thrilled with having finally found Mars’s elusive, visible aurora. “It was so satisfying,” Dr. Knutsen said. Dr. Knutsen suspected that a visible green aurora ...

The model estimated Mars's subsurface water distribution down to 2 meters from the surface. Like a sponge, highly absorptive regolith in Mars's mid- and low latitudes retains substantial amounts ...

It turns out that some of the rocks it found have green stains on them. Of course, this is Mars, the “Red Planet,” so no one expected to see anything like that color there. These are the first ...

In similar rocks to those on Mars, green spots of this kind can be seen, and form when water runs through the sediment before it hardens into rock, which changes the chemical reaction and leaves ...

In March 2024, for the first time, scientists observed a visible green aurora on Mars. Although scientists had already detected many different types of auroras on Mars, they had all appeared at ...

This process supports a chemical reaction that transforms oxidized iron to its reduced form, creating a green hue in the rock. Related: 32 things on Mars that look like they shouldn't be there ...
