M52 and NGC 7635 - Bubble Nebula

 

NGC 7635

 

This area lies just on the border between the constellations Cassiopeia and Cepheus. M52 is a fine open cluster located in a rich Milky Way field. The distance of this cluster is not very well known, measurements indicate something between 3.000 and 5.000 light years.

Situated about 35 arcminutes southwest of M52 is the Bubble Nebula NGC 7635 around the 7th-mag star HD 220057. Within the diffuse emission nebula lies a dark inclusion which appears as a faint and diffuse oval, about 3.5 x 3 arcminutes in size, hence the name "Bubble Nebula". The bubble was probably formed when the nebulous material inside it was blown out by stellar wind of the bright OB star HD 220057. It is difficult to see because of its low surface brightness.
