NGC 7822 is an emission nebula located in Cepheus, about 3,000 lightyears away.
It’s a violent, chaotic deep-sky region where young stars are being born, their powerful radiation ionising the surrounding gas and causing it to glow.
These energetic stellar winds are also carving out the dusty streams and pillars seen throughout the nebula.

Within these dark, dusty regions, new stars are likely being born, but the powerful radiation that’s fuelling NGC 7822’s light emission is also destroying the cosmic gas and dust necessary for stellar birth, effectively cutting them off at the source.
Below is a selection of images of NGC 7822 captured by astrophotographers and BBC Sky at Night Magazine readers.
