NGC 7635<\/strong>, auch Blasennebel<\/strong> (engl. Bubble Nebula<\/em>) genannt, ist ein Emissionsnebel<\/a> und eine HII-Region<\/a> im Sternbild<\/a> Kassiopeia<\/a>, welcher etwa 7100 Lichtjahre<\/a> von der Erde<\/a> entfernt ist. Er befindet sich in der N\u00e4he des offenen Sternhaufens<\/a> Messier 52<\/a>. Die Bezeichnung stammt von einer Sternwind-Blase<\/a>, die durch den Sternwind<\/a> eines O-Sterns<\/a> mit der Bezeichnung BD<\/a> +60 2522 (SAO 20575) entstanden ist. Der Stern st\u00f6\u00dft gro\u00dfe Mengen an Gas aus, die sich mit rund 28 Kilometer pro Sekunde in die Umgebung ausbreiten. Dabei sto\u00dfen die expandierenden Gase auf die riesige umgebende Molek\u00fclwolke<\/a> in dieser Region, die der Ausdehnung Widerstand entgegenbringt. Dadurch bildet sich eine Sto\u00dfwelle<\/a> aus, welche die \u00e4u\u00dfere H\u00fclle der Gasblase bildet.[3]<\/a>
SAO 20575 hat die Helligkeit von 7,8 mag.  (Wikipedia)<\/p>\n\n\n\n
