A newly-hatched baby sea turtle makes its way into the Mediterranean Sea for the first time, as part of the Israeli Sea Turtle Rescue Center's conservation program, at a beach near Mikhmoret north of Tel Aviv, Israel September 9, 2019. Green turtles are endangered worldwide, the World Wildlife Fund says. Among other hazards, they are threatened by hunting, human encroachment on the beaches where they nest, and pollution of their feeding grounds offshore. According to the Israeli rescue center, only about 20 female green turtles nest along the Israeli Mediterranean coast during a breeding season that usually lasts from May until August.

Birds behaviour winner: Land of the Eagle by Audun Rikardsen, Norway. High on a ledge, on the coast near his home in northern Norway, Rikardsen carefully positioned an old tree branch that he hoped would make a perfect golden eagle lookout. To this, he bolted a tripod head with a camera, flashes and motion sensor attached, and built himself a hide a short distance away. From time to time, he left road‑kill carrion nearby. Very gradually – over the next three years – a golden eagle got used to the camera and started to use the branch regularly to survey the coast below.

These stunning light art pictures of skateboarding skeletons were created by Darren Pearson from Los Angeles. He works as a full time illustrator by day and by night he explores the varying landscapes of California in search of the perfect scene for his light-sculptures. Pearson makes complex light-effect photographs, none of which are photoshopped. He describes the work as location-based light art. Photo: A light skateboarder grinding a rail.

At first, British photographer Martin Usborne just wanted to do some reporting on people who leave their dogs locked up in cars. But as he went around scouring parking lots, “making barking noises to try and awaken sleeping dogs that were not actually there,” his project took on a new artistic direction. “The Silence of Dogs in Cars” was inspired by a “childhood memory of waiting in a car whilst his parents were shopping in a supermarket, and the youthful fear that they would not return.”

The antennas of the European Southern Observatory's Atacama Large Millimeter/Submillimeter Array, also known as ALMA, are set against the splendor of the Milky Way in this picture by Babak Tafreshi. Construction of the full ALMA array is due to be completed in Chile's Atacama Desert in 2013, but the facility is already making scientific observations with a partial array of antennas.
