The light of fas planets doesn’t awake us at night. We look at it at daytime with the help of NASA professionals (National Aeronautics and Space Administration). And it’s not an activity in vain. At least these people work day and night so that we can look at secret objects on Google Maps / Google Earth. They help to make earth metals clearer and penetrate some mysteries. But the most important thing is that they make great photos that we can enjoy in our free time.
