Sixty symbols and Dr. Becky. Sixty Symbols started with the Messier objects and now does interesting things to look at. Dr. Becky is an astrophysicist and does a lot of sky and astronomy news. Scott Manley is another good one if you want to hear about rockets

Anton Petrov talks about a lot of cutting edge science, he doesn't do a lot of astronomy, but he does astro-physics.

So not the best if you're just talking star gazing, but if you actually want to know how it works and why it's the way it is, he's a great resource.

He does have a thick Bulgarian accent, which may make it hard to understand at first.
