Look, Up in the Sky! It's a Nebula! It's a Galaxy!

Here's an interesting press release from the National Radio Astronomy Observatory, where I work: "New observations with National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) suggest that what was once believed to be an intergalactic cloud of unknown distance and significance, is actually a previously unrecognized satellite galaxy of the Milky Way orbiting backward around the Galactic center."
