Webb telescope's latest observationsTracking Asteroid 2024 YR4 again this year required some ingenuity. Many astronomers believed they wouldn't get another chance until 2028, but an international team identified two short windows last month — Feb. 18 and 26 — when Webb might still detect the space rock. The telescope observes only a small patch of sky at a time, so astronomers had to predict the asteroid's position with extreme accuracy to point the instrument correctly.
