Each day we feature a different image or photograph of our fascinating universe, along with a brief explanation written by a professional astronomer. 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.
