The Spitzer Space Telescope has spotted what may be comet dust and debris around the white dwarf star G29-38, which died approximately 500 million years ago. The findings suggest the dead star, which most likely consumed its inner planets, is still orbited by a ring of surviving comets...

Wedged in between the bright star Fomalhaut (pronounced fo-ma-lo) to the south and the glittering Pleiades star cluster to the east is the huge, lumbering constellation of Cetus, the Whale. It ranks fourth in overall size among the 88 official constellations; only Hydra, Ursa Major and Virgo cove...

Another of the southern constellations named by Frenchman Nicolas Louis de Lacaille was originally called L'Atelier du Sculpteur, or in English, Workshop of the Sculptor. Later, the name was shortened to just Sculptor. This constellation was formed from a group of stars first charted by de Lacai...
