Cosmic Ghosts Ghouls and Vampires

Astronomers use colorful language for cosmic objects. But unlike ghosts, ghouls and vampires in horror stories, the cosmic ones aren't scary late at night. Here are tales of the birth, evolution and death of stars, a blinking demon and a star that, at Halloween, seems like the Sun's ghost.

Fiery skull. It looks like something in torment, but it's an X-Ray image of the Perseus Cluster of Galaxy. We're not seeing the galaxies themselves, just the X-rays given out by the gas between the galaxies.

The Astronomy Picture of the Day offers up the Ghost Head Nebula for Halloween. This is NGC 2080 taken by the Hubble Space Telescope. It looks as though the ghostly figure has two glowing eyes, but it's actually a star=forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The nebula is about fifty light years across.

For Halloween Night the Astronomy Picture of the Day (APOD) offered us a ghostly aurora over Canada.

Quote:
The aurora definitely appeared to be shaped like something , but what? Two ghostly possibilities recorded by the astrophotographer were "witch" and "goddess of dawn". The pictured aurora had a typical green color caused by the scientifically commonplace action of high energy particles from space interacting with oxygen in Earth's upper atmosphere. In the image foreground, at the bottom, is a frozen Alexandra Falls, with evergreen trees.
