These rocks turned out to contain a mineral called kaolinite, which on Earth forms in warm, rainy environments or near hot springs—places that are ideal for life. Wiens estimates that the rocks—found in an ancient riverbed and strewn uphill on the rim of Jezero Crater—are several billion years old.

Qi Zhang, a doctoral student at the Swedish Institute of Space Physics and Umeå University, explores in her doctoral thesis the interaction between Mars and the stream of charged particles from the sun,

If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have a new potential way to find them

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

With its vivid turquoise, green and blue waters, it’s no surprise Lake Salda is often promoted as the “Maldives of Turkey.” According to scientists, it’s also the only place on Earth that’s analogous to the Jezero Crater on Mars.

A study suggests Mars takes its red hue from a type of mineral that forms in cool water, which could reveal insights about whether Mars was ever able to support life.

Following the 7-planet alignment, Mars will be visible in the sky in March. Here's everything you need to know about this cosmic spectacle and how to watch it.

Now, Mars. Photographs from the NASA Archive, a stunning new release from publisher Taschen, invites us on an extraordinary visual journey through six decades of NASA’s pioneering missions, showcasing the planet’s breathtaking landscapes, its geological wonders, and the relentless search for signs of life.
