Spooky Astronomy, part 2

Ghostly Reflections in the Pleiades. (Image Credit: NASA & The Hubble Heritage Team (STScI/AURA)) One of the hot stars of the Pleiades cluster is destroying a dark cloud of gas and dust. That's producing this wispy specter. The blue color shows that it's reflecting starlight. Mona Evans, "Cosmic Halloween Tour" http://www.bellaonline.com/articles/art52161.asp

Spectral hand and ring of fire? No, it's pulsar PSR B1509-58, a spinning neutron star imaged by the Chandra X-ray Observatory. It's located in the constellation Circinus. The rapid spin is sending charged matter into a strongly magnetized nebula, and creating these amazing shapes.

It's Always 4th of July in the Universe

This looks more like a threatening ghost than either the dear old Horsehead Nebula or anything to do with the Fourth! But it's a Hubble Space Telescope infrared image of the Horsehead Nebula.

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” http://www.bellaonline.com/articles/art43407.asp

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.
