An orphaned giraffe nuzzling a wildlife keeper at Sarara camp in Kenya, one of 70 pictures being sold by Prints for Nature (printsfornature.com) to raise money for work by the Conservation International charity.

Current estimates are that giraffe populations across Africa have dropped 40 percent in three decades, plummeting from approximately 155,000 in the late 1980s to under 100,000 today.

The galactic core of the milky way occupied by two small wooden boats on July 2, 2014, in Isle of Wight, UK. The Milky Way shines in mesmerizing colourful patterns above the Isle of Wight in stunning photographs. Chad Powell used a DSLR camera to capture images of the spectacular constellation above the familiar beach scenes of England's largest island. The 22-year-old, who shot the pictures over a year of stargazing on the island, often stayed up until dawn to catch the most dramatic sky-scapes. Chad, a graphic designer from Ventnor, Isle of Wight, used foregrounds of abandoned theme parks, harbors and lighthouses against the illuminated sky. Minor adjustments were made to bring out the contrast and whites in the images. (Photo by Chad Powell/Barcroft Media)
