NGC 7635 Bubble Nebula

 

Distance from Earth: 11,090 light years

 

NGC 7635 (sometimes known as the Bubble Nebula or C 11) is a diffuse nebula visible in the constellation of Cassiopeia, towards the border with Cepheus.

It is a HII region, at the southern vertex of which there is an empty structure, caused by the pressure of the radiation of a central star of blue color (spectral class O), SAO 20575, of ninth magnitude, whose stellar wind reaches 2000 km / s; it is a blue Giant, which is also responsible for the ionization of the nebula, which emits its own light. Its distance from the Sun is estimated at 11,000 light-years.
