2021 February 18 - Swiss Alps, Martian Sky
Channel: APOD Podcast
Date: 18/02/2021

In today's image, we see a view of the Swiss Alps which resembles the sky of Mars. This is from dust from the Sahara Desert that absorbs the blue light of the sky giving it the reddish color we see from images of Mars.
