A new app from NASA, named NASA Selfies, lets you snap a shot of yourself to overlay on a choice of backgrounds, ranging from the Orion Nebula¹ to the Milky² Way.

美国航空航天局近日（NASA）推出了一款名为NASA Selfies的新应用，用户可以自拍一张照片，叠加在猎户座星云、银河系等可供选择的背景之上。

The NASA Selfies app lets you place your face, or that of your pet, into a spacesuit with a backdrop of stunning³ images taken by the Spitzer Space Telescope of the last 15 years.

该应用允许用户将自己的脸或者宠物的脸P到以斯皮策太空望远镜过去15年拍摄的炫酷图片为背景的宇航服上。

You can then share the image from your camera gallery or within the app to use #NASASelfie. The app is available on iOS and Android now.
