Steve Stewart-WilliamsThis photo of the sun might not look too impressive... until you realize it was taken at night – not looking up but looking down, through the entire Earth, using neutrinos rather than light. Amazing! https://apod.nasa.gov/apod/ap980605.html
Jost Migenda@SteveStuWill Not just at night—that photo was taken using over a year of 24/7 “exposure”.
(Though here’s one of my favorite facts I learned while working on this experiment: We do actually see slightly *more* neutrinos at night, when they have to travel through the whole Earth!)
