Bubble Nebula (NGC 7635)
Space blows
Give the world champion bubble-blower all of the gum ever made and they still couldn't match the mass of this seemingly inflatable space object – seen here as snapped by the Hubble Telescope. The "lungs" that blew up the Bubble Nebula belong to the flared point of light in the sphere's top left – a star called BD+602522, whose stellar winds force gas and dust outwards in all directions, ballooning to a diameter of 6 light years or more. We hate to burst your bubble, but even stars breathe their last eventually. Astronomers think BD+602522 will go supernova in 10 to 20 million years, a cosmic cataclysm sure to make this nebula pop.
