The &#8220;bubble&#8221; is created by the stellar wind from a massive hot central star about 10 to 40 times larger than our own. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. You can also see Cassiopeia&#8217;s open cluster, Messier 52 (NGC 7654), in the upper right of the photo.\u00a0<\/span><\/p>\n<figure id=\"attachment_162\" aria-describedby=\"caption-attachment-162\" style=\"width: 286px\" class=\"wp-caption aligncenter\"><a style=\"color: #993300;\" href=\"http:\/\/13thstone.com\/blog\/wp-content\/uploads\/2014\/10\/bubble.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-162\" src=\"http:\/\/13thstone.com\/blog\/wp-content\/uploads\/2014\/10\/bubble-286x300.jpg\" alt=\"Bubble Nebula (NGC 7635) \" width=\"286\" height=\"300\" srcset=\"https:\/\/13thstone.com\/blog\/wp-content\/uploads\/2014\/10\/bubble-286x300.jpg 286w, https:\/\/13thstone.com\/blog\/wp-content\/uploads\/2014\/10\/bubble.jpg 954w\" sizes=\"auto, (max-width: 286px) 100vw, 286px\" \/><\/a><figcaption id=\"caption-attachment-162\" class=\"wp-caption-text\"><\/span> <span style=\"color: #993300;\">Bubble Nebula (NGC 7635)<\/span><\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Sweet, dark skies.
