Francis Halzen Wins Nobel Prize for Antarctic Neutrino Discovery

Francis Halzen won the Nobel Prize in physics for his work on studying neutrinos.

Neutrinos are tiny particles that have no electric charge and are very hard to detect.

Trillions pass through our bodies every second.

They rarely bump into other matter, so scientists need very large detectors to catch them.

Halzen proposed using Antarctic ice as part of a giant detector.

The IceCube observatory looks for tiny flashes of light made when neutrinos interact with ice.

It detected high-energy neutrinos that came from faraway galaxies.

Halzen said he was surprised by the prize and hoped it would help his research proposal.
