Ghost particle' found in Antarctica provides astronomy breakthrough
For the first time, scientists have been able to trace the origins of a ghostly subatomic particle that traveled 3.7 billion light-years to Earth. The tiny, high-energy cosmic particle is called a neutrino, and it was found by sensors deep in the Antarctic ice in the IceCube detector.

Scientists and observatories around the world were able to trace the neutrino to a galaxy with a supermassive, rapidly spinning black hole at its center, known as a blazar. The galaxy sits to the left of Orion's shoulder in his constellation and is about 4 billion light-years from Earth.
Scientists say the discovery heralds a new era of space research, allowing the use of these particles to study and observe the universe in an unprecedented way. And the finding suggests that scientists will be able to track the origin of mysterious cosmic rays for the first time.
"This identification launches the new field of high-energy neutrino astronomy, which we expect will yield exciting breakthroughs in our understanding of the universe and fundamental physics, including how and where these ultra-high-energy particles are produced," Doug Cowen, a founding member of the IceCube collaboration and Penn State University professor of physics and astronomy and astrophysics, said in a statement. "For 20 years, one of our dreams as a collaboration was to identify the sources of high-energy cosmic neutrinos, and it looks like we've finally done it!"
