A space telescope designed to reveal unprecedented details about exoplanets, which are worlds beyond our solar system, launched early Wednesday morning from French Guiana. You can watch footage of the launch at this link.

The CHaracterising ExOPlanet Satellite (CHEOPS), a joint mission by the European Space Agency and the Swiss Space Office, is the first mission to focus on small exoplanets that have already been discovered orbiting bright stars.
