SUMMARY:Neutrinos on the Rocks\, Physics Department Colloquium\,  Mark
 us Ahlers\, Niels Bohr Institute
DESCRIPTION:Neutrinos are unique cosmic messengers that allow to explo
 re the most extreme environments of our Universe. In the past decade\,
  neutrino astronomy has reached a milestone with the discovery of high
 -energy (TeV-PeV) cosmic neutrinos by the IceCube observatory at the S
 outh Pole. The origin of these neutrinos is unknown and subject to muc
 h speculation in astroparticle physics. Only recently\, IceCube was ab
 le to find first compelling evidence of a high-energy neutrino source:
  the gamma-ray blazar TXS 0506+056. The sum of these observations has 
 implications on the strength and abundance of neutrino sources and the
 ir visibility in terms of other messengers: cosmic rays\, photons and 
 gravitational waves. Multi-messenger astronomy will play a strong role
  for future discoveries. In my talk\, I will summarize the status of n
 eutrino astronomy and highlight the open questions that can be address
 ed with next-generation neutrino observatories and detector upgrades. 
 I will emphasize the unique potential of neutrino astronomy as a probe
  of astrophysics and fundamental physics.
