KISSIMMEE, Florida — 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 is located in the southern constellation of Carina, a ship’s keel, and outshines our own sun by 5 million times.
