Largest map of the universe I could find
(media.kbin.social)
The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here's the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall.

SEA, PBS SpaceTime, Astrum, Dr. Becky, Sixty Symbol, and Anton Petrov. With Anton being the one who is very weedsy with a daily video about a recently-published paper. That's the list of YouTubers I think I recommend checking out.
I don't know how Anton does it. There is something new every day and each video has tons of detail.
Dont forget cool worlds
ParallaxNick, man! His videos - mostly about the history of astronomy - are spectacular, poetic, in-depth, thorough.
ParallaxNick has been doing a series of videos on the lives and works of Copernicus, Tycho Brahe, then Kepler, now Galileo, and I assume Newton is next.
