Earth has blue skies and red sunsets. Mars has red skies and blue sunsets.

The sky on Earth is blue because gas molecules reflect blue light. Earth sunsets look red because all the blue light has already been filtered out.

The sky on Mars is red because dust particles reflect red light. Martian sunsets look blue because all the red light has already been filtered out.

Two planets. Opposite skies.

@InvaderXan it’s really the martian sunsets when one can really grasp just how thin the martian atmosphere is

it’s a bit less evident when it’s midday there

@jasonscheirer @InvaderXan @anarchiv I thought the red martian skies were tinted in post, rather than actually that way; my understanding was that a clear Mars skyscape would be a 'weaker' blue than earth
