Nearly a decade ago an object called G2 first enthralled astronomers around the world. G2 was a bizarre hybrid. Containing several Earth masses of material, it looked like a compact mix of gas and dust, yet it moved more like a star, although telescopes could see no signs of starlight seeping out of its interior. The object might have been dismissed as a random astronomical oddity if it did not also happen to be on a path that would bring it dangerously close to the supermassive black hole parked at our galaxy’s center.
