Scientists have monitored our Galaxy for five years, searching for objects with variable brightness, such as stars in front of which a planet is crossing or systems of stars that orbit and obscur each other. For this purpose the team has been observing the southern night sky on a nightly basis using the telescope at Bochum's University Observatory in the Atacama Desert in Chile. So far, over 50 000 bright variable objects have been detected during the project.
