00:01Deep 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.

00:15An 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.

01:18Independent researchers are modelling the distribution of neutrinos in the Milky Way.

01:30They expect to find particularly large numbers of these high-energy particles,

01:36where charged particles undergo acceleration in extreme magnetic fields and collide with other particles,

01:48presumably in star-forming regions, something that can be tested with IceCube data in the future.

01:55This observation established neutrinos as a new tool of astrophysics,

02:03which let us peer into regions of space from which light cannot escape.

02:09What are we doing here, like,FFSdy Appleships', whereof they were in daylight,

02:19whereof they find esimerk- drill the sourceejons in the future.

02:21They are not as eた to be any daí bleeding.

02:23But what do we think ofম walks across the horizon that are evolving quickly in?
