Pickering s Triangle in the Veil
17.09.2015

Chaotic in appearance, these filaments of shocked, glowing gas break 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.
