Gibson's albatross (Diomedea antipodensis gibsoni) is a large seabird in the albatross family, Diomedeidae, named after the Australian amateur ornithologist John Douglas Gibson. It is found principally in the Auckland Islands of New Zealand, foraging in the Tasman Sea, with most individuals nesting on Adams Island. Gibson's albatross is classified as part of the same species as the Antipodean albatross but is generally paler in colour. Adult birds are white on the back, with white plumage on the head and body and fine grey barring. The tail is white with black edges, except in older males, in which it may be completely white, while the bill is pale pink. This Gibson's albatross was photographed in flight off the south-eastern coast of Tasmania, Australia.

The Battle of Inab, also called the Battle of Ard al-Hâtim or Fons Muratus, was fought on 29 June 1149 during the Second Crusade. The Zengid army of Nur al-Din Zengi destroyed the combined army of Raymond of Poitiers and the Assassins of Ali ibn-Wafa. The Principality of Antioch was subsequently pillaged and reduced in size as its eastern border was pushed west, and both Raymond and his ally ibn-Wafa were killed. This illustration by Jean Colombe was taken from the 14th-century manuscript Passages d'outremer and depicts the Battle of Inab in the main image above, with the recovery of Raymond's body depicted below. It is part of a volume of 66 such full-page miniatures.

Fumarole minerals are minerals that are deposited by fumarole exhalations. They form when gases and compounds desublimate or precipitate out of condensates, forming mineral deposits. They are mostly associated with volcanoes (as volcanic sublimate or fumarolic sublimate), following deposition from volcanic gas during an eruption or discharge from a volcanic vent or fumarole, but have been encountered on burning coal deposits as well. They can be black or multicoloured and are often unstable upon exposure to the atmosphere. This natural-color photomicrograph of fumarole minerals from Mutnovsky, a volcano on the Kamchatka Peninsula in Russia, was taken using a scanning electron microscope. Yellow and red crystals of thallium(I) iodide are visible, with a gradual transition between the two polymorphs. The crystals are located on a substrate of altered rock. This image is 700 micrometres (0.028 in) across on the long side.

Sabella spallanzanii is a species of marine polychaete worms in the family Sabellidae. It is native to the northeastern Atlantic Ocean, Mediterranean Sea and North Sea, but has spread to various other parts of the world and is included on the Global Invasive Species Database. The species grows to a total length of 9 to 40 centimetres (4 to 16 inches) and is usually larger in deep water. It features stiff, sandy tubes formed from hardened mucus secreted by the worm that protrude from the sand, and a two-layered crown of feeding tentacles that can be retracted into the tube. This S. spallanzanii worm was photographed in Arrábida Natural Park, Portugal.

Lord Kelvin (26 June 1824 – 17 December 1907) was a British mathematician, mathematical physicist and engineer. Born in Belfast, he was Professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research, including on electricity and the formulation of the first and second laws of thermodynamics. He was also the first to determine the correct value of absolute zero, and the Kelvin scale of temperature is named in his honour. Kelvin received the Copley Medal in 1883, served as the president of the Royal Society from 1890 to 1895, and in 1892 became the first British scientist to be elevated to the House of Lords. This photograph, taken circa 1900, shows Kelvin resting on a binnacle (the stand for a marine compass) of his invention, and holding a marine azimuth mirror.

The Great Train Robbery is a 1903 American silent film made by Edwin S. Porter for the Edison Manufacturing Company. It follows a gang of outlaws who hold up and rob a steam locomotive at a station in the American West, flee across mountainous terrain, and are finally defeated by a posse of locals. The short film draws on many sources, including a robust existing tradition of Western films, recent European innovations in film technique, the play of the same name by Scott Marble, the popularity of train-themed films, and possibly real-life incidents involving outlaws such as Butch Cassidy.

The sedge warbler (Acrocephalus schoenobaenus) is a passerine bird in the Acrocephalidae family, the reed warblers. It is a medium-sized warbler with a brown, streaked back and wings and a distinct pale supercilium. Sedge warblers are migratory, crossing the Sahara to get from their European and Asian breeding grounds to spend winter in Africa. The male's song is composed of chattering phrases and can include mimicry of other species. The species is mostly insectivorous. This sedge warbler was photographed in Otmoor RSPB reserveinOxfordshire, England.

Long Tack Sam (1884–1961) was a Chinese-born American magician, acrobat, and vaudeville performer. Little is known about his early years, although he is known to have joined a group of acrobats around 1900 called the Tian-Kwai, with whom he toured the world. Several years later, amid unrest in China, he brought his troupe of entertainers to the United States, where he performed extensively for several decades. This colour lithograph poster featuring Long was printed in Hamburg, Germany, in 1919. It illustrates his conscious use of luxurious embroidered costumes and elaborate scenery to enhance his mystique and capitalize on Western notions of "the mysterious Orient".

Pinguicula vulgaris, the common butterwort, is a perennial carnivorous plant in the Lentibulariaceae family. It has a generally circumboreal distribution, being native to almost every country in Europe as well as Russia, Canada and the United States. Growing to a height of 3 to 16 centimetres (1.2 to 6.3 inches), it is topped with a purple and occasionally white funnel-shaped flower that is 15 millimetres (0.59 in) or longer. The plant, which is insectivorous, grows in damp environments such as bogs and swamps, in low or subalpine elevations. Its leaves have glands that excrete a sticky fluid that traps insects to its leaves; its glands also produce digestive enzymes that work to consume the insects externally. This P. vulgaris flower was photographed in Keila, Estonia.

Venus Anadyomene is an oil-on-canvas paintingbyTitian, dating to around 1520. It depicts the Greek goddess Venus rising from the sea and wringing her hair, with a shell visible at the bottom left, taken from a description of Venus by the Greek poet Hesiod in which she was born fully-grown from a shell. The wringing of her hair is a direct imitation of Apelles's lost masterwork, also called Venus Anadyomene. The painting is in good condition and achieved public ownership in 2003 when it was purchased from Francis Egerton, 7th Duke of Sutherland. It is now in the collection of the National Galleries of Scotland.

Sugarloaf Mountain is a peak situated in Rio de Janeiro, Brazil, on a peninsula at the mouth of Guanabara Bay. Rising 396 m (1,299 ft) above the harbor, the peak is named for its resemblance to the traditional shape of concentrated refined sugarloaf. The mountain is one of several monolithic granite and quartz mountains that rise straight from the water's edge in the area, and is geologically part of a family of steep-sided rock outcroppings known as bornhardts. Sugarloaf Mountain also features the Sugarloaf Cable Car and is popular with tourists for its panoramic views of the city and beyond. This photograph shows Sugarloaf Mountain at sunrise viewed from Tijuca National Park, with the Rio neighborhood of Botafogo in the foreground.

The almond (Prunus amygdalus) is a species of tree in the family Rosaceae, the roses. It prospers in a moderate Mediterranean climate with cool winter weather, and is native to Iran and surrounding countries, although it is rarely now found wild in its original setting. The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed; botanically, it is not considered a true nut. It is used extensively as a culinary nut, however, and is cultivated worldwide. Around 80% of the world's almond supply is produced in the US state of California. This photograph shows an almond drupe in shell, shell cracked open, unshelled and blanched seed.

The Heart Nebula is an emission nebula, 7500 light years from Earth, located in the Perseus Arm of the Milky Way in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. Spanning almost 2 degrees in the sky, its shape is driven by stellar winds from the hot stars in its core. The nebula displays glowing ionized hydrogen gas and darker dust lanes, and is also made up of ionised oxygen and sulfur gasses, which cause rich blue and orange colours to be seen in narrowband images. This photograph of the Heart Nebula, with the Fish Head Nebula also visible in the top right corner, is a narrowband image captured on a 70mm scope with a capture period of around 44 hours.

Anoblique shock is a shock wave that, unlike a normal shock, is inclined with respect to the direction of incoming air. It occurs when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. This photograph shows an oblique shock at the nose of a Northrop T-38 Talon aircraft, made visible through Schlieren photography.

The Douglas fir (Pseudotsuga menziesii) is an evergreen conifer species in the pine family, Pinaceae, which is native to western North America. The trees grow to a height of around 20 to 100 metres (70 to 330 feet) and commonly reach 2.4 metres (8 feet) in diameter. The largest coast Douglas firs regularly live for more than 500 years, with the oldest specimens more than 1,300 years old. The cones are pendulous and differ from true firs as they have persistent scales. The cones have distinctive long, trifid (three-pointed) bracts, which protrude prominently above each scale. The cones become tan when mature, measuring 6 to 10 centimetres (2+1⁄2 to 4 inches) long for coastal Douglas firs. This photograph shows a young female cone of the variety Pseudotsuga menziesii var. glauca (Rocky Mountain Douglas-fir), cultivated near Keila, Estonia.

HMS Malabar was a 74-gun ship of the line of the Royal Navy, launched in 1818 at Bombay Dockyard. In 1838, Malabar ran aground off Prince Edward Island in British North America and was damaged, with the loss of two crew members. She was refloated later that year and towed into Three RiversinLower Canada. In August 1843, Malabar, under the command of Sir George Sartorius, assisted in fighting a fire that destroyed the United States Navy sidewheel frigate USS MissouriatGibraltar, taking aboard about 200 of that ship's survivors. Malabar was converted to a hulk in 1848, eventually becoming a coal hulk, and was renamed Myrtle in 1883. The hulk was sold out of the navy in 1905. This lithograph from around 1843 shows the crew of Malabar watching as Missouri explodes and burns in the distance.

Jeremiah Gurney (1812–1895) was an American daguerreotype photographer. Initially working in the jewelry trade in Saratoga, New York, he took up photography after learning of daguerreotype from Samuel Morse, moving to New York City where he began selling photographs alongside jewelry. He was one of the earliest photographers in the city, and may have been the owner of the first photographic gallery in the United States. Gurney took this self-portrait photograph around 1869; it is now in the collection of the Minneapolis Institute of Art.
