CERN Large Hadron Collider Live Webcast in English. It's choppy, but I have too many tabs open, so if you start fresh there seems to be enough bandwidth.

The Large Hadron Collider fired up in Bern and the proto beams are colliding at very high energy, 3.5 TeV each, 7 between them, 3 1/2 times greater than ever before. The first two attempts failed due to a power glitch, but that was straightened out at about 1 p.m. Swiss time (7 a.m. EDT) and they have the stable beams you see above, and the detectors are beginning to collect data.

New particles are being created by this collision, 40 "events" per second. (The screenshot at right displays such a collision event.) Eventually they expect 40 million events per second, said a project scientist.

These are the tracks of these particles as they emerge from the center of the collider:
