Ancient lakes and canyons on the surface of Mars - space short science news

Scientists have found that lakes on Mars contained at times so much water that they overflowed and burst from the sides of their basins. This created catastrophic floods that carved canyons extremely rapidly, possibly even in the matter of weeks.

These observations suggest that disastrous geological processes may have shaped the surface of Mars in the past, before the water became frozen and confined in ice caps.
