NGC 7822 is a region of active star formation located at the edge of a giant molecular cloud in the northern constellation Cepheus. It lies about 3,000 light-years from Earth and is home to many young, hot stars.
Nebula Structure
- The nebula features pillars of gas and dust, as well as brightly glowing edges of structures, giving the region its striking shapes.
- In images of the nebula taken using narrowband filters, emission from oxygen, hydrogen, and sulfur atoms is colored blue, green, and red, respectively. This color scheme is widely used in images taken with the Hubble Space Telescope.
Mechanisms of Glow and Destruction
- Powerful radiation from hot stars provides energy for the glow of these atoms. In addition, strong stellar winds form dense pillars that are gradually destroyed by this radiation.
- As a result, a cavity several light years in size is formed in the center of the cloud, where stars are just beginning their journey in the process of gravitational compression.
The process of star formation
- Stars continue to form inside these pillars, but over time the pillars are destroyed, and young stars will be cut off from the reserves of matter from which they were created.
The nebula NGC 7822 is an excellent object for studying the dynamics of star formation and the interaction of stellar winds with molecular clouds.
