(Newser) – After nearly three years on Mars, NASA's Curiosity rover has captured one of its most stunning otherworldly images yet: a blue Martian sunset. The newly released image was taken on April 15 between dust storms when the thin atmosphere was still full of particles, reports CNET. "The colors come from the fact that the very fine dust is the right size so that blue light penetrates the atmosphere slightly more efficiently," Curiosity team member Mark Lemmon said in a NASA release. "When the blue light scatters off the dust, it stays closer to the direction of the sun than light of other colors does." (NASA also recently captured sounds from the edge of space.)
