<p><a href= "https://www.youtube.com/watch?v=SVkwkzES1DE">https://www.youtube.com/watch?v=SVkwkzES1DE</a></p> <p><strong>Oct 12, 2022.</strong></p> <p>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.</p> <p> </p> <p>So, what's the closest one to us?<span class= "Apple-converted-space"> </span> This video shows a viable candidate, closer than all known so far.</p> <p> </p> <p>We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class= "Apple-converted-space"> </span></p> <p>Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p>Share the podcast with your friends and send the Patreon link to them too!<span class="Apple-converted-space"> </span></p> <p>Every bit helps!
