Astronomers take first photo of the Milky Way using neutrino particles
[ad_1]
Astronomers at the IceCube neutrino observatory in Antarctica have taken the first photograph of the Milky Way galaxy with a neutrino particle detector. This was reported press office observatories.
Neutrino is an elementary particle, which differs in that it practically does not interact with matter, passing through the thickness of the earth’s matter, human bodies and other objects. In order to “catch” neutrinos moving in space at near-light speeds, various detectors are used.
It is noted that the picture of the Milky Way was taken using a detector equipped with more than 5 thousand light sensors. It captures neutrinos reaching Earth from our galaxy and beyond. First, the researchers determined the trajectories of more than 60,000 neutrinos that passed through the Earth’s atmosphere and were detected by the observatory’s sensors. Based on these data, scientists created a three-dimensional map of the movement of neutrinos and compared it with the alleged sources of these particles. The resulting image is the result of this mapping. Studying a snapshot of the Milky Way will help scientists get closer to discovering the sources of these particles, the press service said.
