A crystal made of strontium, iodine, oxygen, and hydrogen looks like an ordinary white powder. But when you squeeze it with a force of hundreds of thousands of atmospheres, a rearrangement begins inside. Iodine atoms, which usually keep their distance, suddenly move closer and form new bonds.

When a massive star runs out of fuel, its core collapses, giving birth to a supernova and unleashing an all-penetrating shower of neutrinos.
