Description

This is the faint Object NGC 7635 (Bubble Nebula), located about 7,100 light-years away in the constellation Cassiopeia. Its originator star burns a million times brighter than the Sun and produces powerful gas 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 is denser in some areas than others. Based on the rate that the star is expending energy, scientists estimate within 20 million years it will explode as a massive supernova, visible as a bright beacon in the daytime sky here. And with that, the bubble will succumb to a common fate: It’ll pop. The Bubble is 10 light-years across, more than twice the distance from Earth to Alpha Centauri, our nearest star.
