Earlier this morning physicists at CERN’s Large Hadron Collider began their scientific programme at 13 TeV. Unfortunately, they lost the beam after about 30 minutes and it will probably be another hour or so before things are up and running again.
You can follow all the excitement via a live webcast.
Good luck to all at the LHC and fingers crossed for finding evidence for physics beyond the Standard Model.
