Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Starburst Galaxy M94
Explanation: The spiral galaxy M94 is somewhat unusual in that it shows a great ring of bright young stars particularly apparent when observed in ultraviolet light , as shown above. Such a high abundance of these young blue stars may cause a galaxy to be designated a starburst galaxy. It is likely that many of the stars seen in the above ring were created when a density wave moving in the galaxy compressed existing galactic gas. The above picture was taken by the Ultraviolet Imaging Telescope during the Astro-2 mission in March 1995.
