The Mouth of the Beast
Glowing menacingly in this new photograph, like the gaping mouth of a gigantic, cosmic creature, is an object called CG4. It is what we call a ‘cometary globule’. These cloudy patches of sky are very different from the lumps of rock and ice we call comets, but they do share a similar shape. You can see the thick, dark, dusty heads and long, faint tails.
