Elusive ‘Geoneutrinos’ Are Building a New Map of Earth’s Volatile Interior
A global network of detectors are reporting some of the most substantial measurements yet of neutrinos created deep underground by the radioactive elements that power our planet’s tectonic activity.

Normally, the cavern is one of the darkest places on Earth, but today it is lit up for maintenance, offering us a rare chance to see inside. I peer through the hatch at Depatie as he paddles over to examine the submerged experiment. He’s inspecting a house-sized detector built to catch some of the most elusive particles known to physics: neutrinos.
This is the SNO+ neutrino experiment, buried deep within the Creighton mine at Snolab, an underground physics laboratory in…
