A scientific balloon designed to make the first-ever measurements of high-energy neutrinos has completed a 35-day flight over Antarctica, said University of Hawaii professor Peter Gorham, who is leading the project.
As the high-altitude balloon cruised at 120,000 feet above the Antarctic continent, 40 antennas listened for bursts of radio waves like "mini-lightning bolts" from high-energy neutrinos interacting deep within the ice.

"At this point we can't say if we detected any neutrinos" - Peter Gorham, professor of physics and astronomy, explaining that most of the data has yet to be analysed by the Antarctic Impulsive Transient Antenna team.
