I still can't get over the first images from the Vera Rubin Observatory. This is the Virgo Cluster, which contains over 1000 galaxies and is 50 million light-years away from us. And, just so you know, when you see a few galaxies that look like they're connected by dust, those are tidal tails from interactions between these galaxies. They are very likely going to collide with one another! See a couple examples in the zoomed in screenshots in the following post.
