From the explanation

“These chaotic and tangled filaments of shocked, glowing gas are spread across planet Earth’s sky toward the constellation of Cygnus as part of the Veil Nebula . The Veil Nebula itself is a large supernova remnant , an expanding cloud born of the death explosion of a massive star.”
