From today's featured articleCrater is a small constellation in the southern celestial hemisphere, one of 48 listed by the second-century astronomer Ptolemy. It depicts a krater, a type of cup used by the Greeks to water down wine, perched on the back of Hydra, the water snake, to its south and west. It has been associated with the mythological god Apollo. It is also bordered by Leo and Virgo to the north, Corvus to the east, and Sextans to the northwest. There is no star brighter than third magnitude in the constellation. Its two brightest stars, Delta Crateris of magnitude 3.56 and Alpha Crateris of magnitude 4.07, are ageing orange giant stars that are cooler and larger than the Sun. Beta Crateris is a binary star system composed of a white giant star and a white dwarf. Seven star systems have been found to host planets. A few galaxies, including Crater 2 and NGC 3981, and a quasar lie within the borders of the constellation. (Full article...) Did you know...

Today's featured picture
The Caribbean reef squid (Sepioteuthis sepioidea) is a species of small, torpedo-shaped squid with undulating fins that extend nearly the entire length of the body, approximately 20 centimetres (8 in) in length. The species is found throughout the Caribbean Sea, as well as off the coast of Florida, commonly in small schools of four to thirty individuals in the shallows associated with reefs. The habitat of the reef squid changes according to its stage of life and size. New hatchlings tend to reside close to the shore, in areas from 0.2 to 1 metre (1 to 3 ft) below the surface, on or under vegetation. This picture shows a Caribbean reef squid in Bari Reef, just off the coast of Bonaire, a Dutch territory in the Caribbean. Photograph credit: Betty Wills |
