[Left] – This is a sky survey image of the Veil Nebula, a 110-light-year-wide expanding remnant of a star that exploded about 8,000 years ago in the constellation Cygnus.
[Center] – This is a ground-based telescope image of a 15-light-year-long stretch of the eastern portion of the nebula.
[Right] – This image shows a two-light-year-wide segment of the remnant as photographed by NASA's Hubble Space Telescope. Hubble resolves tangled rope-like filaments of glowing gases.
About the colours
The Hubble image (right) is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F502N ([O III]) Red: F657N (H-alpha+[N II]) Green: F673N ([S II]) Blue: F555W (V) Red: F814W (I)
About the data
The Hubble image of the Veil Nebula was created from Hubble data from proposals 14056 : Hubble Heritage Team, PI: Z. Levay, M. Mutchler, J. Mack, S. Meyett, L. Frattare, C. Christian, J. Green, and M. Livio (STScI/AURA), and K. Noll (NASA/GSFC).
