A tiny particle that crossed the universe and reached Antarctica may have started its journey inside a distant galaxy wrapped in dust. A new study points to JCMT0402\u22120424, nicknamed \u201cShadow Blaster,\u201d as the most plausible source of a high-energy neutrino detected by IceCube in 2021.<\/p>\n\n\n\n
The finding matters because scientists have struggled for years to explain where many of the universe\u2019s most energetic neutrinos<\/a> come from. This candidate source is not a blazing black hole jet, the usual suspect, but a crowded star-making galaxy<\/a> about 11 billion light-years away. That changes the story.<\/p>\n\n\n\n Neutrinos are often called ghost particles because they barely interact with normal matter. Trillions can pass through your body without you noticing a thing, which is strange to imagine while sitting at a desk or walking down the street.<\/p>\n\n\n\nThe ghost particle<\/h2>\n\n\n\n
