Scientists may finally be close to explaining strange radio signals from beyond the Milky WayFast radio bursts erupt in the sky around 10,000 times a day, but scientists still struggle to explain them. New research could put astronomers one step closer to a solution.
-
An encounter with 'something outside of the solar system' may have triggered an ice age on EarthTwo million years ago, an encounter with a cold cloud of gas and dust could have caused our planet's "protective giant bubble" to draw back, potentially cooling our planet, new research claims.
