Answer : Supernova Remnant

Explanation :

The Veil Nebula is a supernova remnant. It’s a delicate, wispy structure in the constellation Cygnus, formed from the expanding debris of a massive star that exploded approximately 10,000–20,000 years ago. The nebula’s glowing filaments result from shockwaves heating and ionizing the surrounding gas, creating a intricate network visible in optical and X-ray wavelengths.


Why not Emission nebula?
Many supernova remnants, including the Veil, are classified as emission nebulae because they glow from ionized gas, but the specific type is supernova remnant, distinguishing it from H II regions powered by young stars or planetary nebulae from dying low-mass stars.
