Scientists are one step closer to providing David Bowie an answer to his decades-old question, “Is there life on Mars?”

Just this morning, NASA scientists announced that they have found evidence of flowing water on the red planet.

“There is liquid water today on the surface of Mars,” said Michael Meyer, the lead scientist on NASA’s Mars exploration program to The Guardian. “Because of this, we suspect that it is at least possible to have a habitable environment today.”

The revelation comes from data collected by the Mars Reconnaissance Orbiter spacecraft, which indicates that the dark patches that appear on the craters and canyons of Mars—known as the Recurring Slope Lineae—are caused by liquid water streaming down them during the summer months.

In order to come to this conclusion, the Mars scientists devised a new method that allowed chemical signatures to be extracted from individual image pixels, which provided a much high level of resolution that had been achieved before, wrote The Independent.

Life On One Of Saturn’s Moons? Scientists Are Taking Steps To Answer That Question

Outside of Earth, astrobiologists have long regarded the moons Europa and Enceladus as the most likely celestial bodies in our solar system to host life. And now, scientists are in the process of developing a mission concept to see if their hypothesis holds on Saturn’s icy moon, Enceladus.

Researchers Are One Step Closer To “Curing” Color Blindness

Over ten million Americans live with colorblindness, but if Drs. Maureen and Jay Neitz have their way, that number will fall dramatically — and soon.

In 1999, the University of Washington researchers decided to look for a solution to the problem of color blindness, and spent over a decade researching the genetic condition before they proved in 2009 that they could use gene therapy to correct color blindness in male squirrel monkeys, which are born unable to distinguish between red and green, according to The Seattle Times.
