Caldwell 34 (NGC6992 / The Eastern Veil Nebula)
- Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures.
o - The Hubble Space Telescope has captured three magnificent sections of the Veil Nebula – the shattered remains of a supernova that exploded some 7,500 years ago.
o - It’s one of the most famous and beautiful supernova remnants in the sky, forming part of a huge structure called the Cygnus Loop.
o - The nebula’s colours come from
…..– Blue / Green (glowing oxygen)
…..– Red (hydrogen)
…..– Green / Yellow (sulfur)
These appear where the shock wave slams into surrounding gas.

Facts about Caldwell 34 (Veil nebula)
- Caldwell 34 is part of the Veil Nebula, a giant cloud left over from a supernova, when a huge star blew up.
o - It is also nicknamed the Witch’s Broom, because its long, wispy shape looks like a broom sweeping across space.
o - The nebula glows in bright colours because fast‑moving shock waves slam into gas and dust, making them shine blue, red, and green
o - The blast wave is still racing outward at 400,000 miles per hour!
