After an explosion on a neutron star, it cooled down five times faster than usual. The reason: a nuclear 'dance' of particles in its ocean, giving birth to neutrinos. This invisible 'draft' carries away heat like steam from a pot. Now astrophysicists can listen to the 'pulse' of cooling stars to understand what they are made of.
🎯 The name 'Urca' was coined in a casino: physicists George Gamow and Mario Schönberg joked that neutrinos carry away energy as relentlessly as a croupier takes chips.
