Eagle nebula (M16),optical image. This is an emission nebula,a huge cloud of gas that glows pink as the hydrogen gas it contains is ionised by radiation from hot young stars that formed within it. The nebula contains numerous small dark dense globules of gas seen silhouetted against the bright nebula (for instance at centre right). These are thought to be regions in an advanced stage of star formation. The Eagle nebula lies around 7000 light years from Earth in the constellation Serpens | |
