Plants play a huge role in shaping Earth’s climate. Through photosynthesis, they pull carbon dioxide (CO₂) out of the air.

Mars, one of our closest planetary neighbors, has fascinated people for hundreds of years, partly because it is so similar to ...

A team has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen. The findings could ...

potentially shedding light on the Red Planet’s ancient carbon cycle and its past habitability. Though Mars is now cold and barren, geological features such as dry riverbeds and sediment layers suggest ...

This, in turn, was the first evidence we’ve found of the ancient Martian carbon cycle. “Now we have evidence that confirms the models,” Tutolo claims. The carbon from the atmosphere was ...

In other words, billions of years ago, Mars had an active carbon cycle. It's the first in situ evidence of the carbon cycle on Mars, and it represents an important clue about whether or not the red ...

A new study led by a University of Calgary scientist has found evidence that suggests Mars once had a carbon cycle, giving further support for the past habitability of the red planet. Using data ...

When drilling into rocks on Mount Sharp, the central peak of the Red Planet's Gale Crater, the rover found evidence of siderite, an iron carbonate whose presence suggests Mars once had a carbon cycle.

This points to a once-active carbon cycle on Mars, where CO 2 reacted with water and rock to form minerals, only to be partly released back into the air later, hinting at dynamic climatic shifts and ...
