Every second, about 65 billion neutrinos pass through your body and everything around the Earth leaves almost no trace. Scientists already knew two sources of this "ghost particle": the Sun and the supernovae, which are the big explosions of giant stars. Now neutrinos from a blazar – a celestial object that concentrates a lot of energy and is associated with a black hole – have been detected on Earth.
Two studies published in the journal Science Thursday (12) provide details of the discovery The researchers who participated in the studies analyzed the data collected by the IceCube neutrino observatory located in Antarctica.
In 2013, the IceCube detected a type of high-energy neutrino. The scientists then began to search for the source of this particle. In September 2017, a new detection revealed that the direction of neutrino arrival on Earth corresponds to the position of the blazar TXS 0506 + 056. This powerfully astronomical object produces a jet directed towards the Earth while its matter falls in the black hole associated with it.
Motivated by this discovery, scientists made a study of the neutrino recordings detected by the IceCube for nearly ten years before the recent one.
Extremely Light Particles
Neutrinos are subatomic particles that are much lighter than electrons and interact very weakly with ordinary matter. However, they are abundant in the Universe. In addition to their origin in the Sun, neutrinos can be produced in nuclear reactors, in atomic explosions and in the decay of radioactive elements
In the IceCube, neutrino detectors are buried between 1.5 km and 2.5 km. The study of neutrinos is important so that one can understand the fundamental issues of the composition of the Universe, such as its mass, for example.
