NGC 7822 in Cepheus
NGC 7822 is a star-forming region in the northern constellation Cepheus, about 3,000 light-years away. It is filled with hot, young stars and cosmic pillars of gas and dust. This image uses narrowband filters to map emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The energy from the young stars powers this atomic emission, highlighting the bright edges and dark shapes within the nebula.
