These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water.

Oh! No Flowing H2O on The Red Planet?

August 24, 2016

Last September, with much hoopla, NASA confirmed evidence of liquid water flowing on present-day Mars. But a new study using data from the space agency’s Mars Odyssey mission throws some cold water on those findings. About a year ago, the space agency’s Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) onboard the Mars Reconnaissance Orbiter identified […]

Moon Born from a Violent Head-On Collision

February 1, 2016

It’s been theorized by a number of scientists that the moon was formed as the result of a collision between an early Earth and a protoplanet known as Theia, named after the mother of the goddess of the moon in Greek mythology, some 4.5 billion years ago (around 100 million years after Earth formed). But scientists seem […]

NASA Says Water Flows on Mars

September 28, 2015

Today, NASA confirmed evidence of the presence of liquid water flowing on present-day Mars. It’s most likely that any flowing Martian water is salty and not pure. “Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve […]
