The Amazing Bubble nebula, NGC 7635
NGC 7635, better known as the Bubble Nebula, is located about 7,100 light-years away in the Cassiopeia constellation. Its star burns a million times brighter than our sun and produces powerful gaseous outflows called stellar winds that howl at more than four million miles per hour. Over time, the winds have pushed nearby gas and dust outward, forming a layer around the star that’s denser in some areas than others. Based on the rate the star is expending energy, scientists estimate in 10 to 20 million years it will explode as a supernova. And the bubble will succumb to a common fate: It’ll pop. Embedded in a complex of interstellar dust and gas blown by the winds it is a mere 10 light-years wide.. Seen toward the northern boundary of Cassiopeia, astronomers estimate for the Bubble Nebula and associated cloud complex are around 11,000 light-years away,
