Ancient bacteria could persist beneath Mars’ surface

Radiation-tolerant microbes might be able to live beneath Mars’ surface for hundreds of millions of years and may yet persist today, thanks in part — counterintuitively — to the Red Planet’s frigid, arid conditions. In addition to being cold and dry, the Martian surface is constantly bombarded by cosmic rays, charged particles and other radiation ... Read more
