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.

Drawn from Scotland Yard's private collection, the show charts more than a century of violence and suffering, from the murders of Jack the Ripper to IRA and al-Qaida bombings. But it also celebrates the brains, bravery and scientific advances that helped catch perpetrators and solve crimes. (Photo by Alastair Grant/AP Photo)

The “Dancing With Costica” series began when Australia-based photographer Jane Long decided to brush up on her retouching skills. After finding the Costica Acsinte Archive on Flickr, she became fascinated with the images and their subjects, wanting to bring them to life and give them a story. Here: the Costica photo on the left inspired Jane Long to create her version, titled “Innocence”. (Photo by Costica Acsinte Archive/Jane Long)
