Nobel Prize awarded to physicist using massive ice cube to detect 'ghost particles'

Francis Halzen, a Belgian-born scientist, has won this year's Nobel Prize in Physics for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin." Halzen's research has pioneered the use of ice in Antarctica to observe neutrinos, also known as ghost particles." The World's Host Carolyn Beeler learned more from Juanan Aguilar, a physicist and researcher with the observatory.
