Scientist Dr. Stefan Immler was part of a team that captured a new and unique view of one of our closest galactic neighbors with the Swift satellite, which has the ability to detect ultraviolet light. The Andromeda Galaxy, or M31, is a beautiful "nearby" spiral galaxy that is actually visible to the naked eye. We talked with Dr. Immler about what his team learned about the galaxy when Swift took a look in the UV.
