The San Diego Zoo Safari Park's two Sumatran tiger cubs took a catnap after a morning spent exploring their exhibit. Conrad claimed the top spot, while brother Thomas chose to be near, rather than on their mother, Delta.
The 3-month-old male cubs made their public debut on Tuesday and will be on exhibit on Wednesdays, Saturdays and Sundays, from 9 a.m. to noon. The Safari Park is fund-raising to build a new, forested tiger haven that will offer up-close views of these fascinating felines and highlight conservation efforts for the species.

NASA's Aqua satellite caught an arresting image of a rainbow-like optical phenomenon called a glory over the Pacific Ocean on June 20.
Glories can be seen on Earth with the naked eye when looking down upon fog or water vapor, as when climbing a mountain or looking down upon clouds from an airplane.
The phenomenon is caused by light scattered backward toward the viewer by individual water droplets, producing an oscillating pattern of colors ranging from blue to green to red to purple and back to blue again.

Ben Leshchinsky just so happened to be home from his job as a postdoctoral researcher when he decided to try and snap a photo of the lightning from the brief but intense thunderstorm that hit Manhattan this afternoon (June 22).
He lucked out. Camped out on his terrace at his apartment near 67th Street and Amsterdam Avenue, looking northeast toward Central Park, he caught this image of a lightning bolt in action.

Photos of the endangered Amur, or Siberian tiger, have been taken for the first time by a camera trap in a nature reserve in northeast China, suggesting that the cats are expanding their range south from Russia where they are more plentiful.
The two photos were taken in April in the Wangqing Nature Reserve in northeast China's Changbai Mountains. The tiger likely came from Hunchun, close to the Russian border, where multiple images of Siberian tigers were taken in March. Several Amur leopards, which are even more endangered, were also spotted at that time in the Hunchun reserve.

A newly released image from NASA shows off our home planet from an unfamiliar angle our iconic blue marble, snapped by a satellite that circles the Arctic, is arrayed in frosty white.
The newly launched Suomi National Polar-orbiting Partnership (S-NPP) satellite, which was blasted into space on Oct. 28, 2011, circled the Earth 15 times to capture the visual data used for the stunning picture.

The elusive and endangered dhole, or Asiatic wild dog, has been found roaming the forests of four nature reserves in Thailand. Working with photographs snapped by camera traps set up in 15 Thai parks, researchers have created the first map showing where dholes in this region likely live and what areas are suitable habitats for them.
The wild dogs favor areas deep within parks, far from humans. Enhanced protective programs near forest edges could help preserve dholes, which are more likely to be shot or poisoned when they come too close to civilization.

NASA's Aqua satellite caught an arresting image of a strange, enormous weather system off the coast of Tasmania June 5, featuring a cloud hole wider than 620 miles (1,000 kilometers) at one point.
Analysis by NASA scientists found that the hole was caused by sinking air associated with a high pressure system off the surface of the Great Australian Bight, a huge bay to the continent's south. The oval-shaped hole was cut out from a blanket of marine stratocumulus clouds.

For scientist Neil Hammerschlag, it was just another Sunday. He was out cruising the reefs near the Florida Keys, hunting for sharks not as trophies, but for research aimed at keeping them out of display cases and in the water. In many places, these iconic predators are disappearing.
On Sunday, May 27, they were having plenty of luck. Something snagged the other end of the 75-foot (23-meter) line, and Hammerschlag began to pull it in. Right away, he said, he could tell something was different.

For the first time, cameras have documented wild jaguars with cubs in an oil palm plantation in Colombia, a conservation organization announced today (June 6). This is significant for conservationists who hope to protect the wild cats' populations because it indicates jaguars are willing to enter the plantations, which can break up their natural habitat.
The wild cat conservation organization Panthera set up hidden cameras, called camera traps, in an oil palm plantation in Colombia's Magdalena River valley. They ended up capturing photos of two male jaguars and a female jaguar with cubs, as well as a video of a male jaguar.

While the Northern Hemisphere is getting ready for the sunny months of summer, the Southern Hemisphere is heading into winter. This seasonal shift can be seen in a NASA satellite image of snow blanketing southern Patagonia.
Snow is more common in the Northern Hemisphere than the Southern, but long-term observations have shown that parts of southern Argentina and Chile are likely to see snow in June, according to a NASA statement.
