The International Space Station just celebrated its 12th anniversary of having a crew continuously onboard, and to mark the occasion, NASA's unveiled a new service to help folks catch the station in the night sky. Dubbed Spot the Station, the web app texts or emails the time that the ISS will pass over a user's location to their phone. The calculations are done for more than 4,600 places across the globe by NASA's Johnson Space Center, which determines when the ISS will be high enough in the sky to be seen above obstacles such as trees and buildings. Since the station is the second brightest object in the night sky after the moon, it'll appear to the naked eye as if it were a star moving at a steady clip.
