The pair would be lopsided on other scales, though. Embedded in a complex of interstellar dust and gas and blown by the winds from a single, massive O-type star, the Bubble Nebula, also known as NGC 7635, is a mere 10 light-years wide. On the other hand, M52 is a rich open cluster of around a thousand stars. The cluster is about 25 light-years across. Seen toward the northern boundary of Cassiopeia, distance estimates for the Bubble Nebula and associated cloud complex are around 11,000 light-years, while star cluster M52 lies nearly 5,000 light-years away. The wide telescopic field of view spans about 1.5 degrees on the sky or three times the apparent size of a full Moon. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap210925.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>To the eye, this cosmic composition nicely balances the Bubble Nebula at the right with open star cluster M52.
