One of the great mysteries in science
is determining what creates the signals that we detect here on Earth. And for the first time Scientists using NASA's Fermi Gamma-ray, Space Telescope detects the source of the high-energy Neutrino which traveled 3.7 billion years before being identified on Earth. For centuries we’ve been known that peeping through the universe is cosmic rays; originates far beyond our Galaxy. While scientists have been able to unfold some sources of the particles the majority ones that are most energetic, remained a mystery until now as the IceCube Collaboration could detect a cosmic neutrino and identify its sources. The IceCube collaboration, on September 22, 2017, detected an ultra-high-energy neutrino that arrived at the South Pole and was able to identify its source. When a series of gamma-ray telescopes looked at that same position, they not only saw a signal, they identified a blazar, which happened to be flaring at that very moment. At last, humanity has discovered at least one source that creates these ultra-energetic cosmic particles. High-energy neutrinos are hard-to-catch particles that scientists think are created by the most powerful events in the cosmos, such as galaxy mergers and material falling onto supermassive black holes
. They travel at speeds just shy of the speed of light and rarely interact with other matter, allowing them to travel unimpeded across distances of billions of light-years. The discovery of the Cosmic Neutrino was done by an international team of scientists using the National Science Foundation’s IceCube Neutrino Observatory at the Amundsen-Scott South Pole Station. It is important for scientists to study about neutrinos, cosmic rays, and gamma rays in order to have a better understanding of the turbulent cosmic environments such as supernovas, black holes, and stars.
The most extreme cosmic explosions produce gravitational waves, and the most extreme cosmic accelerators produce high-energy neutrinos and cosmic rays. - Regina Caputo, the analysis coordinator for the Fermi Large Area Telescope Collaboration.
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. One of the major goals in building IceCube was to identify the sources of high-energy cosmic neutrinos, and that's one cosmic dream that's at last been achieved.
