A wave of darkness is spreading across Mars. These images show dramatic changes to the Martian surface over the past 50 years, as volcanic dust blows through an ancient impact basin.

In the 1950s, astronomers noticed a seasonal "wave of darkening" on Mars. Some interpreted it as springtime growth of plants. One prominent scientist reported that the "wave" appeared organic, similar to lichen on Earth. Alas...it was just more dust. https://www.centauri-dreams.org/2015/02/27/astrobiology-a-cautionary-tale/ #science #nature #history
