Scientists using data from the Ice Cube Neutrino Observatory in Antarctica believe they have potentially found the first evidence for "ghost particles".
Neutrinos are miniscule subatomic particles that hardly interact with anything.
Astrophysical neutrinos are the name for high-energy neutrinos that come from the farthest reaches beyond our galaxy.
These particles come in three different “flavours”: electron, muon and tau.
The last one has proven to be especially difficult to observe and detect, earning the moniker of “ghost particle.”
