  1. I’ll leave this one to Kyler if you don’t mind. I’m sure he’ll be able to give you a better answer than I could.


  2. we can see a lot of galaxies, but not all of them (some are too faint). But we know the overall number is probably around 100 billion. We know a lot more about nearby galaxies (including our own) because we can see them in more detail. We know how old they are, how many stars they have, how big the massive black hole at their centre is (yes, just about every galaxy has a big black hole right in its middle!). And lots of astronomers are studying all the different galaxies we see to learn even more!



  1. sorry I asked the wrong person but thanks anyway.


  2. thanks for the answers 🙂
