00:00Deep in the Antarctic ice lies the IceCube Neutrino Observatory.
00:07Since 2011, it has been detecting light emitted from particle collisions in the Antarctic ice.
00:14An enormous number of neutrinos pass through the detector every second.
00:20IceCube detects 100,000 neutrinos per year that are created in the Earth's atmosphere.
00:27In contrast, there are only about 100 neutrinos arriving from the cosmos per year.
00:34It is difficult to filter these few cosmic neutrinos out from the rest.
00:39But so far, there has been some evidence that two galaxies are emitting neutrinos.
00:45Researchers of the IceCube collaboration have now succeeded in filtering the large number of neutrinos with the help of machine learning.
00:54Neutrinos can now be found originating from the Milky Way.
01:04We are looking into the future of astronomy research.
01:08New machine learning methods and neutrinos can reveal information from places in the universe that were previously obscured by gas and dust.
01:25Independent researchers are modeling the distribution of neutrinos in the Milky Way.
01:36They expect to find particularly large numbers of these high-energy particles,
01:41where charged particles undergo acceleration in extreme magnetic fields and collide with other particles,
01:49presumably in star-forming regions, something that can be tested with IceCube data in the future.
01:59This observation established neutrinos as a new tool of astrophysics,
02:04which let us peer into regions of space from which light cannot escape.
