This is a small portion of the Veil Nebula - the shattered remains of a supernova that exploded thousands of years ago. The entire structure spans about 3 degrees on the sky, corresponding to about 6 full moons. The image was taken with Hubble's Wide Field Planetary Camera 2 in November 1994 and August 1997.
About the colours
his image is a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F502N ([O III]) Green: F656N (Halpha) Red: F673N ([S II])
About the data
The Hubble image was created from HST data from proposals 5774 and 5779 : J. Hester (Arizona State Universitry) and J. Westphal (Caltech).
