Scientists Weighed the Earth Using Ghostly Particles From Space

Scientists have to use some roundabout methods to weigh the Earth and measure what’s inside it—typically, they’ve used sound waves and the strength of gravity to make their calculations. But one team has weighed the Earth in a whole new way: by measuring mysterious cosmic particles that pass through it. Read More >>

South Pole Experiment’s Hunt for Exotic Neutrino Comes Up Empty

It’s been a rough few weeks of null results for physicists. First, a promising underground experiment failed to find evidence of dark matter. Then news broke that the Large Hadron Collider hadn’t discovered an exciting new particle after all. Read More >>

The Antarctic Neutrino Camera is About to Get Much, Much Bigger

The University of Wisconsin's IceCube neutrino detection system has been quietly operating amid Antarctica's barren tundra for more than four years now. In that time, the fledgling detector has captured more than 100 cosmic neutrinos, many of which originated far outside our Milky Way galaxy. And if project leaders get their way, its imaging quality is about to improve by an order of magnitude. Read More >>

This Subterranean Telescope May Have Just Seen Humanity’s First Cosmic Neutrino

Catching a glimpse of even regular neutrinos—low-energy particles generated in the atmosphere—is difficult enough, but spotting a "cosmic neutrino" left over from the Big Bang has been downright impossible. That is until this cubic kilometer buried under Antartica's frozen wastes started looking. Read More >>
