In a cosmic breakthrough, researchers have detected subatomic ghostly particles from a distant galaxy for the very first time. The key observations were made at the IceCube Neutrino Observatory at the South Pole. And was reported by a team of 1,000 scientists Thursday in two papers in the journal, Science.
Researchers say that the ghostly particles are high energy neutrinos that have traveled through space, zipping unimpeded through people, planets, and whole galaxies.>> So they pass right through material without leaving any signs of their passage.>> They go through walls. They go through the Earth. They come out of black holes.
>> Researchers detected the neutrinos in pristine ice deep below Antarctica's surface. And traced their source back to a giant elliptical galaxy with a massive rapidly spinning black hole at its core called a blazar located 3.7 billion light-years from Earth in the Orion constellation. Astronomers long have relied upon electromagnetic observations to study the universe, but they say that it has limitations.
And neutrinos may provide a new window into space.>> Of course, the critical thing is that they have no electric charge so they are not bent by magnetic fields. So it has a memory, it tells you where it comes from. The problem is then you have to catch them.
>> And that's exactly what scientists did using the IceCube Neutrino detector which has 86 holes drilled over 8,000 feet into the Antarctic ice. Some 5,000 light sensors register small flashes produced during rare instances when a neutrino collides with an atom in the transparent ice. The key detection came on September 22nd, 2017.
