Martian Delta

A color-enhanced image of the delta in Jezero Crater, which once held a lake. Researchers led by CRISM team member and Brown graduate student Bethany Ehlmann report that ancient rivers ferried clay-like minerals (shown in green) into the lake, forming the delta. Clays tend to trap and preserve organic matter, making the delta a good place to look for signs of ancient life. Image credit: NASA/JPL/JHUAPL/MSSS/Brown University.

This is such a cool photo. The colours aren’t real, but you can clearly see the path an ancient martian river once took to get to a lake, as well as the delta it generated by dumping sediment into that lake. If you squint, you can convince yourself you’re looking at a satellite photo of Earth.

Canals after all.
