Sunday SciKu | Martian Microbes

Everywhere we look on Earth, there’s life, including deep beneath the surface, where microbes cut off from our biosphere for a billion years are still feeding on the energy released by the radioactive decay in rocks.

This week, researchers at Brown University published evidence that the same energy source also exists in Martian rocks, providing the fuel for potential subterranean life on the Red Planet.

We already know that oxygen and methane levels in the Martian atmosphere fluctuate seasonally in a way that might suggest the presence of microbial life there now. Proving that there is life on Mars would tell us a lot about the abundance of life in the universe and our place within it.
