SUMMARY: This object looks like a comet, but it's actually a star forming region called CG4. Cometary globules like this are relatively small clouds of gas and dust in the Milky Way. CG4 is about 1,300 light years from Earth; its head is about 1.5 light-years across, and its tail is about 8 light-years long. The head of the nebula is opaque, but it's illuminated by the light from the hot newly forming stars.
