Washington: NASA has rolled out a new app that allows you to take a picture of yourself in a virtual spacesuit, posing in front of gorgeous cosmic locations, like the Orion Nebula or the center of the Milky Way galaxy. Along with the “NASA Selfies” app, the US space agency also launched an exoplanet excursion virtual reality (VR) app that takes VR users on a guided tour of the TRAPPIST-1 planetary system. (IANS)
