Drifting through Cygnus lies Caldwell 34, the Western Veil Nebula. This delicate supernova remnant sits about 1,470 light-years away, the glowing wreckage of a star that exploded thousands of years ago. Its intricate filaments culminate at
Sharpless 103, the Cygnus Loop, is a vast supernova remnant in the constellation Cygnus. Spanning about 3 degrees across the sky, it marks the expanding shockwave of a star that exploded thousands of years ago. It culminates at astronomical

What “supernova” means
Wiktionary · Wikipediasupernova
- nounThe explosion of a star, which increases its brightness to typically a billion times that of our sun, though attenuated by the great distance from our sun. Some leave only debris (Type I); others fade to invisibility as neutron stars (Type II).
A supernova is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the progenitor, either collapses to a neutron star or black hole, or is completely destroyed to form a diffuse nebula. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months.
