WHOA. IS MY HAIR OUT?
The wispy remnants of a massive stellar explosion that occurred 5,000 to 8,000 years ago are captured in ultraviolet by the Galaxy Evolution Explorer (GALEX) 1,500 light-years away in the constellation Cygnus.
The original explosion would have been bright enough to be seen clearly from Earth with the naked eye. The gas and dust seen here were heated by the supernova's shockwave, which still spreads outward from the original explosion. GALEX launched in 2003 and helped scientists uncover the evolution of the early universe, study star formation, and observe black holes, all in ultraviolet wavelengths.
Image description: Blue swirls emanate outward near the center of the photo, appearing dense on the left and right side of the image's midpoint and more wispy in the middle. Blue stars appear all around the image, dotting the blackness of space.
