Astronomers have a narrow window in February 2026 to observe asteroid 2024 YR4 using the James Webb Space Telescope, which could raise its impact odds on the moon from 4 percent to over 30 percent. The asteroid, discovered late last year, poses risks to satellites from potential lunar debris. This observation may determine if deflection missions are needed before a 2032 collision.

A new study warns that the Taurid meteor shower, famous for its Halloween fireballs, may carry hidden dangers from a potential debris swarm. Led by researcher Mark Boslough, the research examines increased impact risks from near-Earth objects in 2032 and 2036. Scientists urge targeted observations to assess and mitigate these threats.
