A few days ago, our site reported that Google will launch a "Sky Robot" to help astronomy enthusiasts study the stars. This program can display the corresponding "star map" based on the current location of HTC mobile phone users. Even cooler, this program can use technologies such as GPS, clock, compass, and accelerometer to tell users the names of the celestial bodies they are pointing at. Not only that, it also has a search function. For example, if the user enters "Saturn", the program will start from the user's position and indicate the location of Saturn with an arrow. The closer you point your device towards Saturn, the arrow color will change from blue to red. Finally, when you find the celestial body, the program will circle it with a ring. It's truly amazing! If you haven't heard that 2009 is the International Year of Astronomy, then don't fall behind. Grab your phone and go explore the universe!
