... October 16, 1995 . Starburst Galaxy M94 . Credit: NASA , Ultraviolet Imaging Telescope . 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. ... Tomorrow's picture: Galaxy Dwingeloo 1 Emerges . ... About APOD | ...
