In Antarctica found a particle from another galaxy

They interact with other matter only by gravity and the so-called weak nuclear force and thus flow through us, Earth and even miles of lead like ghosts.

In 2013, researchers analyzing data from the IceCube Neutrino Observatory near the South Pole in Antarctica discovered higher-energy astrophysical neutrinos and have been seeking their sources ever since.

When the origin of a neutrino couldn't be identified by IceCube the researchers sent their finding to an worldwide network of observatories.

One of the best suspects have been quasars, supermassive black holes at the centers of galaxies that are actively consuming gas and dust.

This sub-atomic particle is a neutrino and their existence is not so much of a mystery (anymore), but where they come from is, as neutrinos are found everywhere.

The findings solve a mystery dating to 1912 over the source of subatomic particles like neutrinos and cosmic rays that dash through the cosmos.

The perceptions were made by the IceCube Neutrino Observatory at the Amundsen- Scott South Pole Station, and affirmed by telescopes the world over and in Earth's orbit. It is located in the constellation of Orion and removed from us by approximately 4,33 billion light years.

In every cubic centimeter of space, hundreds of ghostly, tiny-massed particles known as Cosmic neutrinos can be found, and since its proposal in 1930, scientists were unable to detect the source of the neutrino, until now where we find a new scientific field, that of high-energy neutrino astronomy, officially launching with this discovery. The reason you are blissfully unaware of this constant bombardment is because neutrinos have no electric charge and virtually no mass; properties that have earned it the nickname "ghost" particle and are befitting with the name bestowed upon it, as neutrino literally means "little neutral one".

This time, as Botner and her colleagues report in the journal Science, two observatories, NASA's Fermi Gamma-ray Space Telescope and the Major Atmospheric Gamma Imaging Cherenkov telescope, saw a burst of gamma energy coming from the same location as the neutrino.

That independent observation greatly strengthens the initial detection of a single, high-energy neutrino and adds to a growing body of data that indicates that the blazar is the first known source of high-energy neutrinos and high-energy cosmic rays.

Detecting the highest energy neutrinos requires a massive particle detector, and the National Science Foundation-supported IceCube observatory is the world's largest.

The twin jets of light and elementary particles that emanate from the blazar are so bright because one is pointing directly at Earth. This includes the 8.4-meter Subaru Telescope on Maunakea, which was used to observe the host galaxy of TXS 0506+056 in an attempt to measure its distance, and thus determine the intrinsic luminosity, or energy output, of the blazar. A string of early observations came up blank, but days later Nasa's Fermi Gamma-ray Space Telescope spotted the likely source: a flaring "blazar". "We're beginning to have more than one sense".

When a neutrino interacts with the nucleus of an atom, it creates a secondary charged particle, which produces a cone of blue light that can be detected.

Yasuyuki Tanaka of Japan's Hiroshima University was the first scientist to link the neutrino to a specific blazar known as TXS 0506+056, which has recently shown increased activity. "It is right to say that we are all swimming in neutrinos".

For the first time, astronomers have traced a cosmic neutrino back to where it started its journey out in space.
