The European Space Agency (ESA) successfully launched two spacecraft this morning that should shed light on some of the big questions in astronomy and cosmology, from the origins of the universe to the formation of stars and planets.
ESA's Planck and Herschel lifted off on board an Ariane 5 rocket at 9:12 Eastern Daylight Time from the European Spaceport in French Guiana.
Less than 40 minutes later the two spacecraft radioed back to an ESA antenna in Australia to confirm that they had separated from the launcher as planned. (The video below shows an animation of Planck's separation.) They are on separate trajectories to loop around a point 930,000 miles (1.5 million kilometers) from Earth, well beyond the moon. To lend a sense of scale, ESA has a video showing Herschel's planned trajectory and orbit.

Initial suspicions that a faulty electrical connection between two magnets inside the giant Large Hadron Collider (LHC) caused a helium leak that ultimately shut down the machine have proved correct.
Mechanical damage from the September 19 electrical snafu caused the magnet to release helium into the particle accelerator's 17-mile (27-kilometer) tunnel, the European Organization for Nuclear Research (CERN), which operates the LHC, said today. CERN's investigation confirms its original explanation for the leak.
