From today's featured articleThe Parachute Jump is a defunct amusement ride on the Riegelmann Boardwalk in Coney Island, Brooklyn, New York City. Listed on the U.S. National Register of Historic Places and protected as a New York City designated landmark, it consists of a 250-foot-tall (76-meter), 170-short-ton (150-metric-ton) open-frame, steel parachute tower. The ride has twelve cantilever steel arms radiating from the top of the tower. When it was in operation, riders were belted into a suspended two-person canvas seat, lifted to the top, and dropped; a parachute and shock absorbers slowed their descent. The jump was the tallest structure built for the 1939 New York World's Fair at Flushing Meadows. The ride was moved to its current location in 1941, where it operated until the 1960s, when the Steeplechase amusement park shut down. After a period of neglect, the frame was restored and fitted with a light-show system in 2006. (Full article...)

Today's featured picture
The common blue (Polyommatus icarus) is a butterfly in the family Lycaenidae. It has a wingspan of 28 to 36 millimetres (1.1 to 1.4 in); the upper surface of the male's wings is an iridescent blue with a thin black border, while the female's wings are primarily brown, with a variable amount of blue. The underside has a greyish base colour in males and a more brownish hue in females. Common blues sequester flavonoids from their host plants and allocate these ultraviolet-absorbing pigments into their wings. Females do this more efficiently than males, and it is these pigments that attract males. This photograph shows a pair of mating common blues (male on the left, female on the right) in Yoesden, a nature reserve in Buckinghamshire, England. Photograph credit: Charles J. Sharp |
