Auroras occur in Earth's ionosphere, where charged solar particles collide with atmospheric atoms. New research suggests this may be the best place in the universe to find elusive dark matter, too (Image credit: NASA Goddard)
Earth may be swimming through an ocean of dark matter — and waves in that invisible ocean lapping against our planet's upper atmosphere may generate detectable radio waves that allow us to finally find this elusive component of the universe, according to new theoretical research.
