All 48 stay free. Quick recall: Answer a short question after each episode, track your accuracy, and build a daily streak. NASA, made short: The Hubble feed and NASA's Astronomy Picture of the Day, rewritten into two or three plain sentences, linked to related episodes. 3D Solar System: Rotate, zoom and tap any planet for its facts and related episodes. Lunar calendar: Tonight's phase and illumination, the month ahead, the next four phases and upcoming eclipses with where they're visible.

Built for the dark: A black, low-glare design that's easy on your night vision.
