Sky Hotspots: The Senders of Ultra-Particles Identified ⚡ экспресс
Cosmic rays are particles with enormous energy, flying in from the depths of the universe. Scientists have discovered that their sources are likely in nearby galaxies, where neutron stars collide. It's like tracing footsteps back to specific houses on our cosmic street. Could our stellar neighbors really be the accelerators?
Every day, particles with colossal energy enter Earth's atmosphere—like unsigned letters. Their source long remained a mystery. New research shows: these 'visitors' point to nearby galaxies, where from time to time catastrophes occur—collisions of neutron stars, ultra-dense spheres the size of a city but with the mass of the Sun. Upon impact, they scatter particles like postal items, and some fly straight to us.
The same model explains why the northern and southern hemispheres see a slightly different 'assortment' of particles: simply, the nearest 'post offices'—the sources—are located on different sides of the sky. Previously, it was thought that the composition of rays depends only on energy, but now it's clear: the key to the puzzle lies in the arrangement of the sender galaxies.
🎯 One such particle, smaller than an atom, carries energy comparable to a baseball's impact—like a carrier pigeon delivering a truck.
