Astronomers have spotted a "rogue" planet gobbling gas and dust at a record rate, and they can't explain its baffling behavior.
Although many rogue planets, which float freely through space without orbiting a star, have been discovered before, this one — known as Cha 1107-7626 — appears to be the fastest-growing free-floating planet ever discovered, gorging at a peak rate of 6.6 billion tons (6 billion metric tons) of matter per second, according to observations with the European Southern Observatory's Very Large Telescope (VLT) in Chile and the James Webb Space Telescope (JWST).
