Resumen de Methane blasts liquefied Mars ice for ages
Burps of methane flowing into young Mars's atmosphere might have allowed liquid water to persist through the planet's later dry periods. Rovers and orbiters have found evidence of rivers there 3 billion years ago, suggesting things warmed up enough to stop ice forming, sometimes for a million years. To discover how this happened, Edwin Kite at the University of Chicago and his team simulated the behaviour of deposits of methane ice on Mars. It's basically ice that you can set on fire. You can flick a lighter at it, and get a flame;' Kite says
