Some stars that give birth to Earth-like rocky planets only to later devour those same daughter worlds, and now scientists say they have a way to find the stellar cannibals.
A team of astronomers say they’ve developed a way to detect planet-eating stars using their chemical signature. The new method could bolster the search for alien planets outside our solar system, the researchers say.
Actually, depending on what they find, it could well sink the enterprise. Earth could conceivably be a rare survivor. But we just don’t know.
