☀☀☀☀  SkyView reinvents stargazing. With straight-forward instruction, this app transforms users into astronomers. Simply point your smartphone toward the night sky, and track constellations, planets and even space apparatus. The free version by itself is worth a look, though you get a lot more for $1.99. Skyview’s out-of-this-world graphics are continually updated. Nine million downloads since 2011 make it a  “best iPhone” app. The app can help journalists with everything from meteor showers to finding the star Proxima b for a story on the potential of life on distant planets. Users can easily share their explorations via social media. — Emily Taylor
