Within the Perseus arm of the Milky Means, within the constellation of Puppis, a half dozen huge “bubbles” of hydrogen fuel, heated by intense ultraviolet radiation from close by O-type stars, present spectacular backdrops for stellar nurseries the place new stars are being born. This glowing cloud, generally known as SH 2-305, is an emission nebula, or HII area, illuminated by no less than two O-type stars and possibly a number of others. Such stars reside quick and die younger, shining one million occasions brighter than the Solar with as much as round 90 occasions the mass. This picture was captured by the European Southern Observatory’s Cosmic Gems programme, an initiative to assemble partaking imagery when science observations should not doable.
