Stars, galaxies, meteors and satellites were the subject of App Smart this week as I tested out astronomy apps to help identify objects in the night sky. These apps typically use your phone or tablet’s sensors to display a view of what you’re pointing your device at in the sky in real time, helping you identify planets and constellations. Here are more apps like this to try out:
Star Walk â€" 5 Stars Astronomy Guide is a popular iOS app, costing $3. It has the same kind of dynamic star display as other apps in its class, and it’s easy to use. It’s also jam-packed with imagery and data on the 200,000 stars and planets in its database, and has a calendar so you can keep track of interesting celestial events. I particularly like the beautiful imagery it uses to show constellations and detail on the planets.
SkySafari 3 may be useful for more experienced star gzers. It has data on 120,000 stars and 220 star clusters, nebulae and galaxies, as well as detailed information pages written by professional astronomers. The basic version costs $3 on iOS, but there’s a Plus edition for $15 that has data on 2.5 million stars and can control some wired and wireless telescopes. The Pro edition is $40 and has many more stars and features but is aimed at the serious amateur astronomer.
Alternatively, and much more simply, there’s SkEye Astronomy, available as a free Android app. It has a businesslike feel, and is slightly sparing on user interface touches like icons. But it is powerful, and essentially works in much the same way as Star Walk or SkySafari does. There’s a $9 SkEye Pro version that has more stars in its database and can help you spot satellites too. But the free edition is fine for the casual astronomer. The app is not ideal you’re a complete beginner, however, as it lacks the kind of detailed background data on stars and so on that similar a! pps have.
The benefit to stargazing apps like these is that they also work during the day, or in a city that’s too light-polluted to let you see more than a handful of stars. This means you can turn them on at any time to learn more about astronomy.
Quick call: The Popular instant messaging app WhatsApp has been updated to a new version for Windows Phone 8. It has better support for Windows Live Tile displays and extras like a back-up system.
