This week in news from The Debrief… Scientists say they have achieved the “impossible” by directly measuring zero-point motion in a molecule at its lowest energy state. Meanwhile, researchers in Georgia analyzing fragments of the McDonough meteorite, which crashed through a home in June, are warning that future impacts could pose a far greater, potentially catastrophic threat. And finally, NASA’s James Webb Space Telescope has delivered groundbreaking evidence of a giant planet orbiting Alpha Centauri, prompting astronomers to investigate what they’re calling “the case of a disappearing planet.”

Here’s a look at these, and other stories we’re covering right now at The Debrief:
