Big, dense, and tightly tethered to its home star, the planet is unlike anything astronomers have yet seen—either in our own solar system or afar.The roasted world known as TOI-849b is the most massive rocky planet ever observed, with as much as 40 Earths’ worth of material crammed inside. Perplexingly, TOI-849b’s tremendous bulk suggests that it should be a giant, gassy world like Jupiter, yet it has almost no...…Please be respectful of copyright.
