Deep Astronomy - The Closest Known Black Hole

https://www.youtube.com/watch?v=SVkwkzES1DE Oct 12, 2022. No one knows how many black holes there are in the Universe. Black holes do not emit any light of their own making them impossible to see directly with telescopes. The only way we can detect black holes is by looking at the effects they have on things we can see.   So, what's the closest one to us?  This video shows a viable candidate, closer than all known so far.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
