Earth is bathed in droves of neutrinos spewed by the Milky Way’s stars
About 1,000 of the subatomic particles, born in stars other than the sun, pass through a thumbnail every second
The Milky Way’s multitudes of stars, shown in this artist’s impression based on data from the Gaia spacecraft, create vast numbers of neutrinos, some of which make it to Earth.
