The first extragalactic source of neutrinos has been identified 4 billion light-years from Earth. ULB is part of the international consortium that made this discovery possible. Astronomy of the future is on the move
L astronomy is undergoing a revolution. An international consortium of scientists, including the ULB, has in fact identified for the first time a potential extragalactic source of neutrinos. Through two articles, the prestigious journal Science gives pride of place to the results of this work carried out within the framework of the international project IceCube.
IceCube is a giant telescope whose optical sensors are buried under the ice South Pole. Since 2010, this big cube of 1.000 m of side records the pbadage of stealth neutrinos of very high energies. These are elementary particles produced by extremely violent events in the galaxy and beyond
