  • 'Ghost particle' traced to a 'blazer' galaxy 4B light years away

"Every time we open up a new window into the universe, we learn new things - not just things we expected", Sivakoff said.

Researchers said they have detected high-energy neutrinos that were emitted from a super-massive black hole in a distant galaxy and traveled for 4 billion light years before hitting ice near the South Pole.

The observatory all of a sudden activate a warning for some other telescopes so that they can check some definite coordinates for a possible source.

An global group of astrophysicists has for the first time determined the birthplace of a highest-energy neutrino, almost four billion light-years away from Earth.

"What's special", says Albrecht Karle, another senior IceCube scientist and UW-Madison physics professor, "is we are in the beam".

Washington, Jul 13 (Prensa Latina) An worldwide team of scientists found for the first time the origin of a neutrino from outside the Milky Way, a ghost particle that marks the beginning of a cosmic ray source, the journal Science published today. The optical measurements are the key to more precise measurements of nearly everything we do. In the year 2015, scientists made a Nobel Prize-winning detection of gravitational waves, as predicted by Albert Einstein they are ripples in space-time. Scientists say there is a one in 740 chance the blazar and neutrino connected by coincidence.

"We know that there are these very high-energy cosmic rays being accelerated out there somewhere and it's a century-old mystery where they are coming from", Erik Blaufuss, an astronomer who works on IceCube at the University of Maryland, was quoted as saying. "But with a neutrino flashlight, it will go through and you can see it on both sides".

This research was published today in two companion papers in Science, a journal published by AAAS, the American Association for Advancement of the Sciences.

The neutrino's ability to travel without deviation from its course means its source can be accurately tracked, unlike other types of subatomic particles that can be dragged off course by a magnetic field like the Earth's. To be exact, it has around 300 tera-electronvolts or more than 40 times stronger than the protons being produced by the Large Hadron Collider, which is already the world's largest particle accelerator. But, because neutrinos are so small and because atoms are nearly entirely empty space - if the nucleus of an atom were the size of a grape, the electrons would orbit at an average distance of about one mile - such collisions are rare.

On Sept. 23, only 13 hours after the initial alert, the recently commissioned ASAS-SN unit at McDonald Observatory in Texas mapped the sky in the area of the neutrino detection.

The discovery came when a minuscule flash of light was detected in IceCube, a neutrino detector in Antarctica made from a cubic kilometre of solid ice.

"The era of multi-messenger astrophysics is here", said National Science Foundation Director France Córdova.

An global team of scientists has found the first evidence of a source of high-energy cosmic neutrinos - ghostly subatomic particles that can travel unhindered for billions of light-years from the most extreme environments in the universe to Earth. Then this information was revealed to the other observatories so that to find for the source and the rest of the history. All told, U of A researchers account for four of the five scientists from Canadian universities. It is way better as compared to X-ray vision, which is used by astronomers for many decades.
