Sh2-173, auch bekannt als Phantom der Oper Nebel, ist ein lichtschwacher Emissionsnebel im Sternbild Kassiopeia im Perseus-Arm der Milchstra\u00dfe. Der Nebel hat einen Durchmesser von 77 Lichtjahren und geh\u00f6rt zur OB-Assoziation Cassiopeia OB5, einer Region mit massereichen Sternen, offenen Sternhaufen und weiteren Nebeln. Zu dieser Umgebung z\u00e4hlen auch Sh2-172, Sh2-177, der Dunkelnebel LDN 1282, die Radioquelle KR 98 und der offene Sternhaufen NGC 103.<\/p>\n

Seine Form, zusammen mit dunklen Staubwolken, erinnert an die Maske aus dem Musical Das Phantom der Oper. Der Nebel ist eine aktive Sternentstehungsregion und steht in Wechselwirkung mit einer Superbubble von 380 Parsec Durchmesser, die durch stellare Winde massereicher Sterne entstanden ist.<\/p>\n

Sh2-173 ist extrem lichtschwach und erfordert lange Belichtungszeiten.<\/p>\n

Entfernung zur Erde: ca. 8800 Lichtjahre<\/p>\n

( Umrechnung: 1 Lichtjahr = 9,5 Billionen Kilometer )<\/p>\n
