    Astronomers working at the IceCube Neutrino Observatory in Antarctica have for the first time ever detected cosmic neutrinos.

    Astronomers at the IceCube Neutrino Observatory in Antarctica announced that they have, for the first time, observed 28 very high-energy particle events or cosmic neutrinos.  The new IceCube detector can capture the astrophysical particles that are nearly massless and stream to Earth at the speed of light from outside of our solar system.  From where these neutrinos originate is a mystery.   Are they from supernovae, did they emanate from gamma ray bursts, or were they accelerated from an accreting black hole?  Scientists say they just don’t know yet.  They did say, however, that, “this is an important observation because it means that somewhere in the universe, there are high-intensity sources near a “central engine” and lots of collisions are occurring to produce the neutrinos.”
