A serene turquoise glow glimmers from underneath these powerful icebergs. Stood in the middle of Antarctica, the giant icebergs appear to be from an unearthly world. These stunning photographs were captured by American photographer Michael Leggero. “My images show pure nature, as that is how I describe Antarctica, simply pure nature”, says the 43 year old, of Carthage, New York. “It is the only place on our planet that humans have not left a presence behind”.

These incredible pictures look like a bird's-eye view of a faraway alien planet – but they're actually hot springs.

In one of the planet’s most desolate and harsh terrains, the Altai Mountains which run from Siberia in Russia down to Mongolia’s Gobi Desert, hunting with eagles is currently only practiced by a handful of Kyrgyz and Kazakhs. This form of falconry, the practice of hunting with the aid of birds of prey, can be traced back as far as 4,000 years in Central Asia. Here: after a successful hunt, a proud hunter rewards his eagle by feeding it the lungs of the prey, which is considered the most highly prized part of the animal.

NASA says it could be another 20 years before humans touch down on Mars, but in a sense, the Mars Society has been exploring the red planet for more than a decade – in Utah. Photo: Csilla Orgel, a geologist of Crew 125 EuroMoonMars B mission, makes her way back to the Mars Desert Research Station (MDRS) in the Utah desert March 3, 2013. The MDRS aims to investigate the feasibility of a human exploration of Mars and uses the Utah desert's Mars-like terrain to simulate working conditions on the red planet. Scientists, students and enthusiasts work together developing field tactics and studying the terrain. All outdoor exploration is done wearing simulated spacesuits and carrying air supply packs and crews live together in a small communication base with limited amounts of electricity, food, oxygen and water. Everything needed to survive must be produced, fixed and replaced on site. (Photo by Jim Urquhart/Reuters)

“Eye of a toad”. Animal Portraits, Łukasz Bożycki, Poland. Early spring sees a pond near Łukasz’s home city of Warsaw, Poland, full of mating frogs and a few toads. On this March day, Łukasz shared the pond with them for an evening, sitting in the icy water in his chest-high waders, keeping as still as possible, despite the numbing cold, so that the amphibians could get used to him. “I wanted to find a fresh way of portraying the amphibians”, he says, “at water level”. Using a telephoto lens, he focused on one lone toad and waited for the sun to dip almost below the horizon before pressing the shutter, using flash to bring out the details in the shadow. His prize was “the glorious pool of sunset colour” and fiery glow of the toad’s eye. Nikon D80 + 70-300mm f4.5-5.6 lens + extension tube; 1/125 sec at f9 (-2.3 e/v); ISO 100; built-in flash.
