Another lousy photo of the sun?

As a photo of the sun this doesn’t look very impressive – until you realise it was taken using neutrinos!

And also that it was taken through the earth – when the sun was on the other side of the earth!

An exposure of 503 day was used and neutrinos detected using a 50 000-ton water pool located 1 km underground. Neutrinos have an extremely weak interaction with other matter. Most of them pass through the earth without interaction and the detection relies on Cherenkov radiation emitted during a rare interaction with an electron in the water.
