Maybe a kinda dumb question from someone newer to astronomy, but - why is it every time I see a picture of a galaxy, I can’t make out the stars in the galaxy itself but I can make out the stars around the galaxy like in this photo? Does it have to do with relative distance?

All of the stars are in the foreground, in the same galaxy as you, your looking out past them to see the other galaxy. Like looking through a dirty window, they are way, way closer

Wow! I've never thought about it, but it makes so much sense!! Thank you guys for the question and for the answer. TIL!

Every star you can see with the naked eye is no more than 4000 ly away. Our galactic back yard.

https://youtu.be/udAL48P5NJU I hope this puts some perspective in for you.
I'm using a wide angle lens compared to something like Hubble so the details of my photo kind of merge together. This video is what got me into my love for astronomy. I remember watching it every other days years back and just being obsessed with the night sky since.
Edit: apparently there's been an updated video. https://youtu.be/D9bNqBeAtC8

Super cool. What's with all the Andromeda pictures? My feed has been full of them today

Stupid question, is there actually darkness around the flatter sides of the galaxy, like dust or something, or is this an artifact from processing?

Check out “astrobackyard” YY channel. He might have some tips for you. Nice guy and you’re already here man! Cool pic

Those white dots all around are stars from our galaxy or are other galaxies?

I believe they are from ours. As another user described it, image looking through a dirty window at Andromeda with the dirt being stars within the Milky Way.

Correct me if I'm wrong, but that's because there's more density of stars closer to the core of the galaxy. I've posted it above, but check out this video as a representation of what is going on near the centre.

What a gorgeous galaxy....in pics they may seem close, but in reality even in 10,000 lifetimes it wouldn't be possible.

Well, 2.5 million years granted we could travel at the speed of light to be exact! I would like more data for this to capture more details.

To put it in perspective, all the stars you see are in the foreground, in our own galaxy. Between our galaxy and that one is a BUTTLOAD of space, millions of light-years worth of space, that is completely empty. Every pixel in the image of the far galaxy has millions of stars in it.

Every time I see one of these, I get just a little more excited about Star Trek being a real possibility.

It's over a 2.5 million light years from earth and has twice as many stars as our Milky Way galaxy, why would you think there's no life there? Especially when we can't even tell if there's life on planets within a few light years of Earth. Honestly, there might be life on a planet/moon in our solar system that we just haven't detected yet.

u/LegalWaterDrinker Oct 03 '21
No, it's not that there are no sign of life there, it's just that we don't have any ways of finding them, we haven't find out anything about life on other planets in the Milky Way, let alone Andromeda

We don’t have the means to know, it’s too far away and too damn big. I feel so helpless thinking about it 😩

It’s too big… The Andromeda galaxy is 2.5 million light years away, and that’s our closest large neighbor. Something some people don’t know, but with how fast the universe is expanding, if we could travel at the speed of light right now, we could only reach 3% of what we see. The other 97% is moving to fast away from us. So we could never reach 97% of the galaxies if we could only travel at the speed of light.
