Scientists have produced an image of the Milky Way not based on electromagnetic radiation - light - but on ghostly subatomic particles called neutrinos. They detected high-energy neutrinos in pristine ice deep below Antarctica's surface, then traced their source back to locations in the Milky Way - the first time these particles have been observed arising from our galaxy.
The neutrinos were detected over a span of a decade at the IceCube Neutrino Observatory at a U.S. scientific research station at the South Pole, using more than 5,000 sensors covering an area the size of a small mountain.
School of Physics Professor Ignacio Taboada is the spokesperson for the IceCube Neutrino Observatory and provides a brief commentary on this new research:
"This observation is ground-breaking. It established the galaxy as a neutrino source. Every future work will refer to this observation," says Taboada.
