Ten thousand years ago, before the dawn of recorded human history, a new light would have suddenly appeared in the night sky and faded after a few weeks. Today we know this light was from a supernova (an exploding star) and resulted in the expanding debris cloud known as the Veil Nebula, a supernova remnant. This image is centered on the western segment of the Veil Nebula cataloged as NGC 6960 but less formally known as the Witch's Broom Nebula. Blasted out in the cataclysmic explosion, the interstellar shock wave plows through space sweeping up and exciting interstellar material. The glowing filaments are like long ripples in a sheet seen almost edge on, remarkably well separated into atomic hydrogen (red) and oxygen (blue-green) gas. The complete supernova remnant lies about 1,400 light-years away in the constellation Cygnus. This portion of the Veil Nebula spans about 35 light years. The bright star in the frame is 52 Cygni, visible with the unaided eye from a dark location but unrelated to the ancient supernova remnant.
