Halloween In Space: Creepy Entities Discovered In The Universe
As Halloween approaches, we look to the mysterious depths of the universe and find ghostly apparitions, spectral hands, skulls, wizards and witches. Or at least these are the descriptions applied by NASA to the jaw-dropping observations they have made.
This ghost-like nebula involves a small star-forming region filled with dark dust that was first noted in images taken by the IRAS satellite in infrared light in 1983. This image from the Hubble Space Telescope shows many new details,but has not uncovered a clear cause of the bright sharp arc. Researchers do not yet know what is lighting up IRAS 05437+2502,a small,faint nebula that spans only 1/18th of a full moon toward the constellation of the Taurus. Particularly enigmatic is the bright upside-down V that defines the upper edge of this floating mountain of interstellar dust.
