More space news, this time further out into the solar system: the two Mars rovers are still trucking along, but scientists here on Earth are working on a thorny problem related to the red planet.

New research suggests that water may have flowed over Mars’ surface in at least one place over the past billion years–relatively “recently,” since the planet has been around for about the same 4.5 billion years as our own–giving more credence to the idea that life may have once existed there, according to ScienceNOW.

A while back, the rovers confirmed that water covered the surface of Mars about four billion years ago, when it was much warmer. But now that the planet is cooler and drier, we’ve only found small bits of evidence here and there. That’s beginning to change, though.
