NASA Confirms “Dark Finger” Marks on Mars Are Signs of Water

The Marks Made By the Water Are the First of Their Kind Ever Found on Another Planet

NASA has confirmed the “major scientific discovery” of signs of flowing water on Mars.  The “dark finger” marks on the red planet had been a source of speculation since they were first spotted in 2011.  These marks lengthen and darken from spring to early fall.  Nasa has announced these marks are evidence of flowing water either on or underneath the surface.

This points to a likely ocean beneath Mars’ icy exterior and may move us a step closer to finding extraterrestrial life.  The next step for Nasa is to use the data to extract a sample of the water and then test for any organic life.
