Bubble Nebula, NGC 7635

NGC 7635, also known as the Bubble Nebula, is 10 light-years wide and is expanding at 4 million miles per hour (7 million km/h). The large star seen in the upper right of the bubble is believed to be about 10 times larger than our sun and the energetic source of expansion for the bubble. It is 7,100 light-years away in the constellation Cassiopeia.
