APOD

每日一天文图（APOD）每天显示新的NASA太空图像。

Developed in partnership with NASA, Astronomy Picture of the Day (APOD) brings the vastness of space right into your hand. Browse through decades of high resolution NASA space photos hand selected by NASA astronomers. Jump to photos by date, save them to your photo roll, set as your device wallpaper, or share them with friends. Select your favorites for easy viewing anytime. And, see previews and descriptions for video APODs. Want that latest Hubble photo as a background? Then APOD is for you.
