Google Earth is in full swing, and now Google has set its sights on the skies above our heads – the stars. According to a report by the UK Telegraph today, Google is preparing to launch a mobile phone application called "Star Droid" to help amateur astronomy enthusiasts study the night sky and identify various constellations, planets, and stars. The search engine of the "Star Droid" app will use the GPS built into the phone to determine the user's location. After positioning, the app will display relevant astronomical data from Google's database to the user. Perhaps this app can restore some of the original appearance of the starry sky that has been obscured by light pollution (as more and more cities stay lit all night, light pollution is getting increasingly severe), allowing people to recognize some hazy constellations and other celestial markers through their phones. Unfortunately, it seems that this app can currently only be downloaded on Google Android system phones. There are rumors that the app may soon be made available to other mobile platforms. Personally, I feel that Google's strategy has never been one of stagnation, so making it available for download is just a matter of time. It’s possible that Google believes it's still too early to open it up at this moment.
