A photo of the constellation Andromeda with all Bayer-designated stars marked and the IAU figure drawn in

Andromeda is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Located north of the celestial equator, it is named for the princess in the Greek legend, who was chained to a rock to be eaten by the sea monster Cetus. Its brightest star, Alpha Andromedae, is a binary star, as is bright Gamma Andromedae, a colorful binary and a popular target for amateur astronomers. The constellation's most obvious deep-sky object is the naked-eye Andromeda Galaxy (M31, also called the Great Galaxy of Andromeda), the closest galaxy to the Milky Way and one of the brightest Messier objects. In Chinese astronomy, the stars that make up Andromeda were members of four different constellations that had astrological and mythological significance; a constellation related to Andromeda also exists in Hindu mythology. Andromeda is the location of the radiant for the Andromedids, a weak meteor shower that occurs in November. (more...)

    Chicago River

    A view west along the main stem of the Chicago River, a system of rivers and canals that runs through Chicago, Illinois, US. Though not especially long, the river is notable for being the reason why Chicago became an important location, as the link between the Great Lakes and the Mississippi Valley waterways. Buildings such as Trump International Hotel and Tower in the center and Aqua (gray building with turquoise "streak") are among the prominent structures depicted. On the right is the cleared land that was awaiting redevelopment as the Chicago Spire. This photo is from the Link Bridge with Streeterville region of the Near North Side community area to the north and the Lakeshore East and Illinois Center regions of the Loop to the south.
