Saw this in an Astrokobi YouTube video. This is how big our neighbor Andromeda galaxy would be if we increased the brightness of it.
It would be way larger than the moon and as the galaxy gets closer to the Milky way, it will get larger until the galactic collision in 2 billion years or so.

It’s really too bad it doesn’t actually look like that. So many more people would be interested in astronomy and science I feel.
It’s so large it makes me sad that it’s so faint to the naked eye
I just did the math. My pension isn’t going to last for 2 billion years so I guess I will miss the collision 😯
I’d love to see a time lapse video of 2 billion years watching Andromeda approach…
I doubted that was true or accurate so I did a short Google search and found what I think might be the source of that image.

TLDR: It’s true but that image is zoomed in and does not give a correct sense of scale.
Edit: actual source was on the article : http://www.reddit.com/r/spaceporn/comments/1u0dxs/andromedas_actual_size_if_it_was_brighter/
Now check out whether owls have sensitive enough eyes to see it.
It gives us time to eat ice cream.
This is very wrong! ( I hate this image)
Galaxy images are scaled so that the dimmer parts are brighter, which let’s you see way more detail.
In truth it would be a very bright core with only a little big of detail visable
Edit: tbf the post only says size, so it is correct. But I hate this image so much for the other reasons I said haha
When I used to do flights in Afghanistan, I’d take a pair of nightvision goggles and just stare at Andromeda. It was so beautiful, but I wish I could have seen it that clearly in its natural colors.
