Liquid water flowing on Mars right now

For decades, space scientists have searched Mars for signs of water, the liquid generally believed to be essential for life. Now, they may well have found it.

It’s a discovery that, if confirmed, would fundamentally change our understanding of Mars and would strongly support the widely held theory that the planet was once far more wet and warm. Scientists say the discovery of water would provide our best target yet for finding possible life beyond Earth.

Using a powerful camera on a spacecraft in orbit around the red planet, scientists have spied what may be small streams of salty water flowing on Mars during warm seasons. Scientists have identified seven craters in which dark, finger-like features appear and seem to flow down slopes or tiny gullies during late spring. The most plausible explanation is that these features are caused by salty water. Learn more here or here.
