Survey of Super Massive Black Holes Completed

eldavojohn writes "NASA has announced the completion of a survey of nearby supermassive black holes. Every galaxy that revolves around a supermassive black hole within 400 light-years of our own galaxy has been cataloged. From the article: 'Called active galactic nuclei, or AGN, these black holes have masses of up to billions of Suns compressed into a region about the size of our solar system. The all-sky census, performed using NASA's Swift satellite over a nine-month period, detected more than 200 nearby AGN.' I'm starting to feel very lucky to have grown up in the Milky Way Galaxy."

  1. 400 light years isn't that far... by mhotchin · · Score: 5, Informative

    400 lightyears? Didn't the submitter read the article?

    It's 400 *million* light years.
