Largest Galaxy Ever Observed
Our Milky Way is considered one of the most sizable galaxies in the universe, with a diameter of 126 thousand light years, but it pales in comparison to the recently discovered IC 1101, the largest that scientists have ever observed, including its central, super-massive black hole.
IC 1101 is colossal with a unfathomable diameter of nearly 6 million light years. To put that number in perspective, you could string 40 Milky Ways in it if you lined them up side by side. The galaxy contains more than 100 trillion stars and is like its own little universe. The following video, presented by Beyond, examines the properties of the galaxy, how it formed and at takes a peek at its ultra-massive black hole.
