KISSIMMEE, Fla.—Scientists have discovered five supersize stars in other galaxies on a par with the monstrous stellar system in our own Milky Way.
Eta Carinae is the brightest and most massive star system within 10,000 light-years of us.
The binary system outshines our own sun by five million times.
But at the American Astronomical Society’s annual meeting Wednesday, Rubab Khan, a researcher at NASA’s Goddard Space Center in Maryland, reported on the discovery of five “Eta twins.”
Khan said the discovery will shed light on the evolution of these stellar heavyweights.
