Martian Sunset Captured by NASA’s Perseverance Rover
Mashable shares the unusual Martian sunset captured by Perseverance.
On Twitter, the space agency explained this sunset’s muted colors. In short, there wasn’t much dust in the atmosphere when the rover looked up and snapped a picture. If there’s more dust in the atmosphere (and Mars is a notoriously dusty desert planet), more blue light wavelengths make it through the dust than other colors. “Fine dust in the atmosphere permits blue light to penetrate the atmosphere more efficiently than colors with longer wavelengths,” NASA explained. “This sunset looks different: less dust in the atmosphere resulted in a more muted color than average.”
