Neutrinos from a Galaxy 47 million light years away!

There is Neutrinos from a galaxy about 47 million light years away from earth and in its center is supermassive Black hole. The conditions are very dense there, so dense that even light has some difficulty coming out. But the small particle called Neutrinos can very easily pass through it. There were hundreds of millions of Neutrinos but out of them only 80 Neutrinos were discovered below the continent, Antarctica through a telescope.
