I was reading today that, in research published in The Astrophysical Journal, molecular oxygen has been discovered in the Markarian 231 galaxy, 561 million light-years from Earth. A light-year, which measures distance in space, equals about 6 trillion miles.

So that's something 561 million x 6 trillion miles away. Good luck getting Excel to calculate that!!

And yet we can't photograph the Apollo landing equipment 243,000 miles away.

This isn't a "moon landings were faked" troll, just an observation that you can see why people may think that way.

Thoughts?

    $\begingroup$ Please don't ask this on the main site. It is completely opinion based / open ended and is a terrible fit for space exploration stack exchange. $\endgroup$ – Organic Marble Feb 22 at 18:36
  • $\begingroup$ Hi @TimRichards, don't worry about the down votes here. You've asked in this in meta and here votes don't count towards your reputation. Instead, they are just a way for people to express themselves. I understand that you're not a "moon landings were faked" troll, but we do get them every once in a while, so sometimes people overreact. $\endgroup$ – uhoh Feb 24 at 10:57

I could explain the reasoning, but as this is meta, I'll say what I think of such a question.

There could be a valid question as to why we can detect oxygen a very long ways away, while we can't see something on the Moon. This kind of question isn't really on topic on this site, but could be on astronomy.

I don't use Excel, but LibreCalc very easily tells me your sum comes to around $3\frac{1}{3}$ sextillion miles.
561,000,000 x 6,000,000,000,000 = 3,366,000,000,000,000,000,000

I would suggest such comments indicate those spreading such doubts either have a poor grasp of the scales of space, or are deliberately misrepresenting them.

It boils down to the lander is small, the galaxy is far away

(please note, they're not photographing molecules of oxygen at that distance)
