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]
