The 'ghosts of the universe', or
cosmic neutrinos, have been detected for the first time in a
blazar, a galaxy centred on a huge black hole, according to the
Antarctic-based IceCube experiment which alerted NASA's Fermi
telescope.
Another 15 experiments, some of them Italian, also saw the
blazar.
The discovery was announced in the United States on Thursday.
The so-called ghosts are seen as "messengers of the new
astronomy," sources said.
Many Italian universities and research institutes took part
in the discovery.
They include the Space Agency (ASI), The National Institute
for Nuclear Physics (INFN) and the National Institute for
Astrophysics.
