We know that there are natural particle accelerators in the universe. We have seen such energy rich cosmic radiation that we, with the technique of the LHC in Cern, would have to build a particle accelerator of the size of the orbit of Mercury to reach this level. Read more:

We already had several webpages which dealt with IceCube and cosmic radiation and neutrinos:


2012 Apr 28 Astrophysics: Where does the cosmic radiation come from?
2012 May 27 The Suns energy-producing fusion reactions
2013 May 21 Where do neutrinos come from
2013 Oct 11 Weakness of will shortcomings. Responsibility. Word.
2013 Oct 30 Dark matter stays hidden as detector fails to see a single partice
2013 Nov 22 News about neutrinos
2014 Mar 02 Blessing of prayer Power out of God - Neutrinos
2015 Apr 16 (2) Theoretically neutrinos explain existence itself

Now follow extracts from an article:

 

Balzan prize winner 2015 Francis Halzen with his team has lowered over 5000 sensors into the ice of Antarctica. The aim is a new way to look at stars.

STANDARD: With the IceCube project in the Antarctic you have for the first time tract down cosmic neutrinos, smallest particles which travel through space. The discovery could establish a kind of astronomy. How does that work?

Halzen: We generate a new map of the universe as astronomers have done so already often. They study it with the free eye, with telescopes and in the end with the help of radio waves. With it they have scanned the sky for all kinds of possible wavelengths of light. But with very small wavelengths also this kind of astronomy ends. With cosmic neutrinos on the other hand one can look into space with a new kind, also with these very small wavelengths. Neutrinos penetrate matter, what photons, components of light and every electromagnetic radiation, do not can.

STANDARD: Where lies the origin of these neutrinos?

Halzen: We know that there are natural particle accelerators in the universe. We have seen such energy rich cosmic radiation that we, with the technique of the LHC in Cern, would have to build a particle accelerator of the size of the orbit of Mercury to reach this level. We know that these fantastic objects are out there, but we do not know what they are. Black holes, neutron stars or pulsars can provide so much energy. Where there are such accelerators there are also neutrinos.

STANDARD: How do they come into being?

Halzen: The particles out of the cosmic particle accelerators interact with light and dust, which are around these objects, and produce neutrinos. When we can therefore catch the particles, we can follow back their path and so use for astronomic purposes.

STANDARD: So it would be a map of a destructive universe?

Halzen: Exactly. When we identify these gigantic accelerators, we can try to study their physics. It is a new possibility, not just for astronomy, but also for physics.

STANDARD: Where do you stand in the process to locate the origin of neutrinos?

Halzen: The key is statistics. We collect more and more data about neutrino collisions in the ice. We have already hundreds of proofs. The most promising beginnings are that we correlate the photons, which the astronomers see with the neutrinos. The astronomers know what they see. Out of this correlation we derive the origins of neutrinos. That has not been brought to an end, but it looks promising. I believe our experiment holds the answer.

Knowledge:

IceCube uses accidental collisions of neutrinos with atomic nuclei. The interaction produces a blue shine, which the sensors record. Direction and energy of the particles can be calculated out of the data. Their origin in the universe is to be determined this way. Researchers hope moreover that one could find out more about dark matter through them.
