Hubble Reveals Ultraviolet Galactic Ring

Release date: Nov 1, 2001 9:00 AM (EST)

The appearance of a galaxy can depend strongly on the color of the light with which it is viewed. This Hubble Heritage image of NGC 6782 illustrates a pronounced example of this effect. This spiral galaxy, when seen in visible light, exhibits tightly wound spiral arms that give it a pinwheel shape similar to that of many other spirals. However, when the galaxy is viewed in ultraviolet light with NASA's Hubble Space Telescope, its shape is startlingly different.
