Webb telescope has a new mission: surveillance of a threatening asteroid

The Webb telescope is well-suited to identify asteroid 2024 YR4's size. Webb views a type of light we can't see with the naked eye, called infrared. Infrared light is largely heat energy, allowing Webb to observe the heat from distant objects, whether they're planets or distant galaxies.
