This mother of all self-portraits was shot on Wednesday by Japanese astronaut Aki Hoshide while on a six-and-a-half hour spacewalk outside the International Space Station. If this doesn't make you swear off duckface mirror smartphone selfies forever, you're beyond redemption.
The EXIF data in the photo—which was uploaded to NASA's 2Explore Flickr feed—shows that astronaut was using a Nikon D2Xs with a 10.5mm fisheye lens at f/11, 1/500, and ISO 200. Co-starring Aki (pun totally intended) is the sun, shining bright in the left-hand corner of the image. [2Explore via PetaPixel]
