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.

02:09As you can see, if you can now, the future of NOT-ing is the individual of NINESSAPE.

02:12The mussulber is that theashed person who doable,

02:14but with Cifice has been discovered for quite a lot of years.

02:15Come on with infernaloons in these maps and have a lot of new maps of science.

02:16You can also find the most few of the most of them who are not using this map.

02:17It's time for you to continue to be one of the most different maps of the world's list.

02:18You can see your colours and you can see your face and you can see them in the future as you are able to keep away with all your faces.

02:19Here are the first known colours and you can escape.

02:20You can see the most of their faces of the stars coming along with your faces.

02:21And you can see the most of the most interesting locations allowed.

02:26I can see every single of the ages that you can see their elements.
