Can you see the face in space ? Blue eyes, a dark nose and mouth with curly red hair…. The red in space is ionised hydrogen and blue is atomised oxygen. Cosmic pillars of cold molecular gas and clouds of dark dust – often called elephant trunks – lie within NGC 7822. Powering the nebular glow are the young, hot stars of the Berkeley 59 cluster, whose powerful winds and radiation also sculpt and erode the dense pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cut off from their reservoir of star stuff…..
