On Earth Day this year, NASA asked people all around the world a question: “Where are you on Earth Right Now?” To answer this question people were asked to post their selfie on social media. The goal was to use each picture as a pixel in the creation of a “Global Selfie” – a mosaic image that would look like Earth appeared from the space. The 3.2 gigapixel “Global Selfie”, was made the with 36,422 individual images.

Throughout the course of the long war in Afghanistan, Coalition troops have relied on thousands of military working dogs to help keep them safe, and make their jobs easier. The dogs are trained to detect explosives, to find illegal drugs, to search for missing comrades, or target enemy combatants. Not only are they active on the front lines, but behind the lines they serve as therapy dogs, service dogs, and loyal companions. They also share the same risks as the ground troops, suffering injuries and sometimes death on the battlefields. Gathered here are images of these dogs and their handlers in Afghanistan and back home, from over the past several years, part of the ongoing series here on Afghanistan.

Far from the fancy throngs who gather at the Pebble Beach Concours d'Elegance every year, another collection of car enthusiasts strive to cough up the worst cars imaginable. The Concours d'Lemons gathers the Edsels, Yugos and Azteks of yesteryear to give the freaky and foul their day in the sun.

Postcards for Ants is an ongoing painting project by Cape Town artist Lorraine Loots who has been creating a miniature painting every single day since January 1, 2013. The artist works with paint brushes, pencils, and bare eyes to render superbly detailed paintings scarcely larger than a small coin. After the first year, Loots relaunched the project in a second phase inspired by Cape Town’s designation as World Design Capital 2014.

My name is Jakub and I’m a painter, illustrator & concept artist who lives and work in Poland. My speciality is dark fantasy, character design, concept art and portrait. Since several years I work and paint digitally, but I never gave up traditional drawing and painting. For me the most important in my work, is create unique atmosphere and tell some kind of story through my creations.

The number of soldiers on both sides of WWII that were killed or went missing is just staggering. Now, the mystery surrounding one RAF pilot and what happened to him and his plane has been solved after 70 years. RAF flight Sergeant Dennis Copping climbed into his Kittyhawk P-40 aircraft in June 1942 to fly the plane to another airbase for repairs. He was never seen or heard from again.

Image patterning has existed for hundreds of years; however, before Thomas Yang no one has ever thought of putting paint on the bicycle wheels and using it as a patterning tool to create very interesting-looking pictures. Being an avid cyclist and an artist, Thomas Yang has decided to combine the two, creating the 100copies. The name of this project not only alludes to the fact that only one hundred copies of those pictures were going to be made, but also to the fact that the pictures themselves consist of hundreds of repeating shapes. And even though the project is called 100copies, no two pictures are alike due to the nature of their creation, making them truly unique. (Photo by Thomas Yang)
