SkyMap is THE astronomy application. It uses compass information + GPS to determine where you are looking and gives you a detailed map of the night sky, complete with names, constellations and more. Having trouble finding a specific celestial body? No problem, just search for the object and SkyMap will guide you to it.
Use this app to answer any questions you may have about what you’re looking at. Need to know the mass of a planet or the distance of a star? The WolframAlpha database knows all that and more. This app is just a quicklaunch to the website but the included math keyboard and voice search will definitely tide us over until a dedicated Android app is released.
Look directly into the sun without scorching your retinas. This app downloads images sent to NASA by duel satellites orbiting the sun. Check out the surface of Earth’s most important star using 3 different filters to view sunspots, storms, flare ups and other phenomenon.
