COMMENTS ON THE OBJECT :
Pillars of gas and dust and young hot stars are massing in the heart of NGC 7822. Located at the edge of a giant molecular cloud in the northern constellation of Cepheus, this star-forming region is some 3000 light years away. The image includes data obtained through filters that distinguish the emissions of atomic oxygen, hydrogen and sulphur in blue, green and red respectively. These emissions are fuelled by the radiation of hot stars which, combined with the powerful solar winds, sculpt and erode the densest pillars. Stars could still be forming inside the pillars by gravitational collapse, provided the pillars have not lost their substance before the baby stars have reached sufficient size to initiate nuclear fusion reactions.
