In fairness, if I recall correctly, if it weren't for interstellar dust and light pollution, Andrommeda would have roughly six times the angular diameter in the night sky as the moon.

According to this if the andromeda was fully visible, it would be like six times bigger than the moon.

Wow, I'm kinda bummed we can't see it like that.

It's still much bigger than people think.

We were on a group retreat and I convinced by office mates to look at the sky (we were next to a glacier in one of the darkest skies I have ever seen) and Andromeda is big! The general comment by everybody was "I thought it was something you cannot see without a telescope, or something tiny that you need to enlarge to see". But it's actually a big object in the sky!

That's awesome! I'll definitely have to look for it.

You can barely see Andromeda as a small ghostly pale splotch with the naked eye in a very dark sky. A slightly more resolved splotch if you use binoculars (you can see the centre splotch plus hazy oval splotch around it). It will be nothing like the well-defined colourful galaxy you see in photos. Just FYI :)

Ah, ok. Thank you for the info!

You're welcome. Here's kind of what it looks like in actuality (although even this photo shows it brighter than it actually is--the stars in the photo, for example, are brighter than they'd appear even at a very dark-sky site): https://p1-tt.byteimg.com/origin/pgc-image/26a4289388a84090929e80b9fcbc930b.jpg

It really just looks like a small very faint hard-to-find fuzzy ball to the naked eye in real life.

Hmmm, that's odd--I tested it and it was broken for me too, but I just tried again and it seems to be working. Maybe it was temporarily down?

It’s still a beautiful splotch tho

really makes you realize the absurd scale of galaxies, even being so far away andromeda can still take up a tremendous amount of space in the sky, i hope i can go someone with little to no light pollution one day to see it

Well you can, just need more help than just your eyes. Hence the telescopes. But it would be really need to see in the sky if you could see it with eyes alone.

Dude, obviously. What did you think he meant?

Yeah I see your point. It was late and I was falling asleep and didn't read it right. Also said need instead of neat for what it is worth.

It's relatively easy and affordable to get equipment that'll let you see it like that

If we were to go to the moon… would we see Andromeda more clearly from there?

Imagine public visits to the moon with the added bonus of seeing Andromeda like that
