Unprecedented neutrino discovery is a "Nobel Prize in the making"

By drilling a 1.5 mile hole deep into an Antarctic glacier, physicists working at the IceCube South Pole Observatory have captured 28 extraterrestrial neutrinos — those mysterious and extremely powerful subatomic particles that can pass straight through solid matter. Welcome to an entirely new age of astronomy. » 11/22/13 12:45pm 11/22/13 12:45pm

What do electrons look like? Now we know.

If you've ever looked at a model of the atom, you'd probably guess that electrons are spherical. But these elementary particles are actually slightly egg-shaped...and proving that could mean trouble for one particular model of subatomic physics. » 5/25/11 5:30pm 5/25/11 5:30pm

The Large Hadron Collider may soon prove supersymmetry theory is wrong

Supersymmetry holds that all the subatomic particles we know have counterparts that are almost exactly the same, only much, much heavier. But the Large Hadron Collider hasn't found any supersymmetric particles yet, and they're running out of places to hide. Will we have to come up with a new model for subatomics? » 3/01/11 4:00pm 3/01/11 4:00pm

The Undiscovered Particles on the Edge of Known Physics

Yesterday, we presented a comprehensive guide to the world of subatomic particles, exploring all the known elementary and composite particles. But now it's time to put certainty to one side and explore the wild, mind-bending world of undiscovered particles. » 9/17/10 4:00pm 9/17/10 4:00pm

The Ultimate Field Guide to Subatomic Particles

Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles. » 9/16/10 10:44am 9/16/10 10:44am
