the universe is so huge, that it’s hard to get a scale of how big it is.
some of the galaxies we see are very similar to ours; with spiral arms, a glowing center, and a mixture of glowing stuff around the middle. the galaxy NGC 772 is no exception. it has a lot on common with our galaxy, with spiral arms, and dwarf galaxies orbiting around it. those are tiny galaxies going around the “big guys”. the two big guys in our galactic neighborhood are the milky way(surprise!) and the andromeda galaxy(no surprise there.).
one of NGC 772’s spiral arms has been distorted by one of these tiny galaxies! (named NGC 770) (visible in the image below)
cool!
