Its story

3 Geminorum is a colossal oddity: a massive blue B-type star whose distance is estimated around 326,000 light-years away, far beyond the disc of the Milky Way, in the galaxy's distant halo or even outside it. If that figure —notoriously hard to pin down for such remote objects— is correct, its light departed in the depths of an ice age, when Neanderthals were still hunting mammoths across an ice-bound Europe.
