Using the James Webb Space Telescope (JWST), astronomers from MIT and other institutions have determined that asteroid 2024 YR4 will not collide with the moon, reports Ashley Strickland for CNN. “Every time we observe an asteroid, we reduce the range of possible trajectories,” explains Prof. Julien de Wit. “In this case, the JWST observations both provided very precise positional measurements and significantly extended the time span over which the asteroid has been observed.”
