Vampire star at work. Artist's concept of blue straggler and its companion. The red giant, losing its outer layers to its companion, will end up as a white dwarf. The other star - the blue straggler - appears to be much younger, than it is, for it has been "feeding" off the other one. (Credit: Aaron M. Geller)

DR 6 nebula ("Galactic Ghoul"). This is a star-forming region in the constellation Cygnus, with the central region (the "nose") about 3.5 light years across. The nebula's nickname comes from its resemblance to a ghoulish face, with cavities in the cloud looking rather like two eyes and a devouring mouth. (Credit: S.

Little Ghost Nebula. (NGC 6369) (Credit: Hubble Heritage Team, NASA) A planetary nebula in the constellation Ophiucus over 2000 light years away. William Herschel discovered it in the18th century. It's round like a planet, but was actually formed from material ejected by a dying star. What remains of the star is the white dwarf near the center. The nebula's main ring structure is about a light-year across. Mona Evans, “Nebulae” www.bellaonline.c...

Witch's Broom Nebula. It's part of the Veil Nebula (NGC 6960), the remains of a supernova that exploded more than 15,000 years ago.

The Ghost Nebula (vdB 141). It's a reflection nebula in the constellation Cepheus. The light of stars embedded in the nebula give it the brown color that looks a bit liked dried blood.
