One of my favorite astronomy related YouTube channels is Deep Sky Videos. The creator, Brady Haran, produces videos for some of the most popular science channels on the Internet. His Deep Sky Videos channel takes viewers behind the scenes and in to one-on-one interviews with astronomers, cosmologists, and serious amateurs. Today he posted an interesting video about M82. I thought it might be nice to share it in case you hadn't run in to his videos before. https://www.youtube.com/watch?v=X0PgDIHBs7s Brady often posts 'un-cut' segments from his interviews. He has added additional content regarding M82 here: https://www.youtube.com/watch?v=nzLQuvIbyko -Ryan
