The Dune collaboration might observe neutrinos from a supernova in our galaxy – if luck is on their side

A global collaboration will aim to unravel the mysteries of neutrinos – also known as “ghost particles”.

Among the goals of the venture, formed earlier this year, will be to catch neutrino particles streaming towards us from a supernova – an exploding star.

Such events occur about every 30 years, but the neutrino streams they produce have not been studied in detail.

Dune (Deep Underground Neutrino Experiment) will be hosted at Fermilab in Batavia, Illinois.

It will involve the development of the world’s most high-intensity beam of neutrinos, which will travel 1,300km (800mi) underground from Fermilab towards a massive detector instrument based at the Sanford Underground Research Facility in South Dakota.

The venture is the product of a merger between European and US projects with similar aims. The international collaboration held its inaugural meeting at Fermilab in April.
