Webb found a hidden giant planet by detecting its atmospheric chemistry through a bright debris disk. For years, a third giant planet remained concealed within the bright dust surrounding Beta Pictoris, one of the most closely observed planetary systems in the Milky Way. NASA’s James Webb Space Telescope has now exposed the hidden world by [...]

Study suggests a new method for tracking electronic and vibrational dynamics in real time. Within a few trillionths of a second after absorbing light, a molecule bends out of shape, shifts its electrons, and converts electronic energy into vibrations. These changes happen too quickly for ordinary instruments to follow, but flashes from the European XFEL [...]
