I thought Mars was a lot bigger. Doesn't look big enough for a Musk colony.

I thought that was Mars dodging around the Moon last night. :-)

That’s a tall ladder
DrDadJokes
how? it make look like Mars is even closer than we perceive it
Easykehl
Here’s a hint: this picture was not taken on/near the moon.

That's heckin wicked, man

It's a composite. Physics cannot get both in focus at those distances.
DavidBrooker
While it's true that only one plane can be in focus, depth of field grows with distance from the lens. 'Physics' absolutely can get both 1/2
in focus at the same time. Indeed, many small aperture devices have such an enormous depth of field (often something like 15cm to 2/3
infinity is not uncommon on phone cameras) that the ability to adjust focus is omitted altogether. Any claim about depth of field is 3/4
machine specific, *not* a claim of physics. 4/4

Aren't most photos of things in space composites?
'Most' would probably require qualifying a lot of other words in that sentence, but essentially all professional or serious amateur 1/2
images of celestial objects are composites. 2/2
So... Yes?
