This image was taken before the advent of color film. It is composed of three monochrome pictures shot through different colored filters and could only be viewed at the time via projection. It was only with digital image processing that the images could be satisfactorily combined into one.
"Earthrise", the first occasion in which humans saw the Earth seemingly rising above the surface of the Moon, taken during the Apollo 8 mission on December 241968. This view was seen by the crew at the beginning of its fourth orbit around the Moon, although the very first photograph taken was in black-and-white. Note that the Earth is in shadow here. A photo of a fully lit Earth would not be taken until the Apollo 17 mission.
The Weedy sea dragon (Phyllopteryx taeniolatus) is a marine fish related to the seahorse. It is native to the shallow water around the southern coastline of Australia, between Port Stephens and Geraldton, as well as Tasmania. Weedy sea dragons are named for the weed-like projections on their bodies, which serve to camouflage them as they move among the seaweed beds where they are usually found.
A female mallard and ducklings. Mallards are probably the best-known of all ducks. The breeding male is unmistakable, with a green head, black rear end and blue speculum feathers edged with white. The female mallard is light brown and can be distinguished from other ducks, by the distinctive speculum.
Photograph from the mid-1870s of a pile of American Bison skulls waiting to be ground for fertilizer. Bison were hunted almost to extinction in the nineteenth century and were reduced to a few hundred head by the mid-1880s, from which all the present day's managed herds are descended. The commercial take arguably was anywhere from 2,000 to 100,000 animals per day, though there are no statistics available.
Comet Hale-Bopp sails across the sky in the vicinity of Pazin in Istria, Croatia. To the lower right of the comet the Andromeda Galaxy is also faintly visible. The comet was visible to the naked eye for a record 18 months, twice as long as the Great Comet of 1811. At perihelion, it shone brighter than any star in the sky except Sirius, and its two tails stretched 30-40 degrees across the sky. The passage of Hale-Bopp was notable also for inciting a degree of panic about comets not seen for decades. Rumours that the comet was being followed by an alienspacecraft gained remarkable currency, and inspired a mass suicide among followers of the Heaven's Gatecult.
Morphology of a sterile female worker wasp. It can be identified as a female by both the number of divisions on its antenna and by its sting. This particular wasp is very close in likeness to a yellowjacket found commonly all around the world.
The eastern face of the Matterhorn, reflected in the Riffelsee. Perhaps the most familiar mountain in the European Alps, the Matterhorn sits on the border between Switzerland and Italy. The peak has four faces, facing the four compass points, with the north and south faces meeting to form a short east-west summit ridge. Despite its prominence in a general sense, the Matterhorn is not among the top 100 mountains in the Alps measured by topographic prominence. Several of its close neighbors, including Monte Rosa, the Dom, Liskamm and the Weisshorn, have higher summits.
Migrant Mother, Dorothea Lange's 1936 photograph of Florence Owens Thompson and her daughters in Nipomo, California, became the most famous image of the Great Depression in the United States. It is one of the classic photographs of the 20th century, and is now an icon of resilience in the face of adversity. In the 1930s, the FSA employed several photographers to document the effects of the Great Depression on the population of America. Many of the photographs can also be seen as propaganda images to support the U.S. government's policy distributing support to the worst affected, poorer areas of the country.
The Cheetah (Acinonyx jubatus) is an atypical member of the cat family that hunts by speed rather than by stealth or pack tactics. It is the fastest of all land animals and can reach speeds of up to 70 mph (120 km/h) in short bursts up to 500 yards (500 m). The cheetah is well known for its amazing acceleration (0 to 100 km/h (~62 mph) in 3.5 seconds which is faster than the Mercedes-Benz SLR McLaren, the Lamborghini Murciélago and the F/A-18 Hornet).
A composite photo of the Orion Nebula, the closest region of star formation to Earth. It is composed of 520 separate images and NASA calls it "one of the most detailed astronomical images ever produced". The nebula is located below Orion's Belt and is visible to the naked eye at night. It is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely-studied celestial features.
