Bubble Nebula

wind-blown bubble · NGC 7635

7,100 light-years from Earth

The wind of a single star about 45 times the Sun's mass, blowing at 1,700 km/s, has inflated a bubble seven light-years wide in the gas around it. The star sits off-centre because the cloud is denser on one side.

• 7,100 light-years · the bubble is 7 light-years wide
• its star, BD+60 2522, is about 45 times the Sun's mass
