A map of Arches National Park near Moab, Utah, United States, detailing the location of many of the more well known natural arches, as well as many other physical features. The park is known for preserving over 2,000 arches, including the world-famous Delicate Arch. It is 119 square miles (310 km2) in size. Its highest elevation is 5,653 feet (1,723 m) at Elephant Butte, and its lowest elevation is 4,085 feet (1,245 m) at the visitor center. Since 1970, forty-three arches have toppled because of erosion. The park receives 10 inches (250 mm) of rain a year on average. Map credit: Justin Morris

Ludwig Schnorr von Carolsfeld and his wife Malvina as the title characters of Richard Wagner's Tristan und Isolde, sometime during the opera's initial run, though, given the demands of early photography, most likely not in an actual performance. The opera was extremely difficult on its leads—it had to be delayed when Malvina temporarily lost her voice, and Ludwig died three weeks after the fourth show. Photo credit: Joseph Albert

Larvae of Culex mosquitoes. As seen on the picture, larvae make dense groups in standing water, where they feed for about one or two weeks before turning into a non-feeding but usually mobile pupa, one of which can be seen near the centre of this group, near the water's surface.

This diagram of four pulley systems illustrates how increasing the number of pulleys increases the mechanical advantage, making the load easier to lift. MA is the factor by which a mechanism multiplies the force put into it. In this diagram, 100 newtons is required to lift the weight off the ground. Each additional pulley increases the MA such that the four-pulley system only needs 25 newtons to accomplish the same task, but the rope must be pulled four times as far.

The "Hampden" Elizabeth I of England was painted by the Flemish artist Steven van der Meulen in the mid to late 1560s. Art historian Sir Roy Strong has suggested that this is "one of a group produced in response to a crisis over the production of the royal image" as a number of old-fashioned and unflattering portraits of the queen were then in circulation. This is the earliest full-length (2 m or 7 ft tall) portrait of the young queen, and depicts her in red satin trimmed with pearls and jewels. It represents a phase in the portraiture of Elizabeth I before the emergence of allegorical images representing the iconography of the "Virgin Queen". In November 2007 it was auctioned by Sotheby's for ₤2.6 million, more than twice the maximum predicted.
Artist: Steven van der Meulen

A parabolic antenna, a high-gain reflector antenna used for radio, television and data communications, at Erdfunkstelle Raisting, the largest facility for satellite communication in the world, based in Raisting, Bavaria, Germany. Parabolic antennas work by reflecting electromagnetic radiation off the paraboloid dish to or from the feed horn (center), for reception or transmission respectively. Photo credit: Richard Bartz

An exuvia . Within one or two hours, the cuticle hardens and darkens, during which time the animal grows, since growth is otherwise constrained by the rigidity of the exoskeleton. Each frame of this image was taken at one-minute intervals, with a 30-minute gap in middle while the cicada rested. The entire process took about 2 hours to complete.

Sir John Tenniel's illustration of the Caterpillar for Lewis Carroll's classic children's book, Alice's Adventures in Wonderland. The illustration is noted for its ambiguous central figure, which can be viewed as having either a human male's face with pointed nose and protruding lower lip or as the head end of an actual caterpillar, with the right three "true" legs visible. The small symbol in the lower left is composed of Tenniel's initials, which was how he signed most of his work for the book. The partially obscured word in the lower left-center is the last name of Edward Dalziel, the engraver of the piece. Artist: Sir John Tenniel

Eta Carinae, a hypergiant luminous blue variable star in the Carina constellation and one of the most massive and most luminous stars yet discovered, and the bipolar Homunculus Nebula which surrounds it. The nebula was partly created in an eruption of Eta Carinae, whose light reached Earth in 1843. Eta Carinae itself appears as the white patch near the center of the image, where the two lobes of the Homunculus touch. Photo credit: Hubble Space Telescope |
