galaxy too NGC 1068 called, is 47 million light years away from the earth. In its center is a particularly active supermassive black hole.

10 years observation period

The researchers explained that it is not possible to determine the origin of a single neutrino in broadcast. You had to do in the past 10 years Information from the total 80 particles Collecting.

Neutrinos can come from very extreme places High density Fly towards the ground. her way is not from issue still from electromagnetic field affected. This means, for example, that they can fly across the entire Earth without disturbance. They have a very low mass and a neutral charge.

Among other things, they are used to monitor things that would otherwise remain hidden. An example is sun core, where neutrinos are created by fusion reactions. Others are galactic nuclei that Planes (material deflected by the black hole and ejected into space) does not refer to Earth, as is the case here.

Now the IceCube team has a black hole at the heart of spiral galaxy Note Messier 77. Instead of looking up at the sky, the telescope looks deep into the sky Antarctica ice. It is not the neutrinos themselves that are being measured, but UV lightthat they left behind. In 2020, IceCube has been expanded with 700 sensors, now leading to a boom in research with small particles.

A breakthrough in neutrino astronomy

Astronomers have already done extensive research on Messier 77. It is known that there is a lot of dust and gas around the black hole. Radiation and light are blocked by it, but not neutrinos. It makes it possible to see the black hole that was previously hidden.

New observations could help make Messier 77 a new one scientific reference to make similar things. It should help to better understand the environment of supermassive black holes. The researchers concluded from the results that black holes contribute significantly to the number of neutrinos in space.

The IceCube team describes their work as A breakthrough in neutrino astronomy. In combination with optical and radio telescopes, new possibilities are now available for measuring neutrinos and gravitational waves and thus examining objects in space. study was Science Magazine chest.
