  • Velocity & Diffusion: Coverage exploded across 6 distinct news outlets with 6 published articles, achieving a live velocity of 4.
  • Primary Driver: A 222‑metre lunar crater, the biggest ever seen forming, has emerged since 2024, offering a rare 'once‑in‑a-century' glimpse of fresh impact debris.
  • Source Integrity: Verified strictly against primary headline reporting under zero-hallucination protocols.

222‑metre crater discovered on the Moon after NASA’s orbiter flagged a bright spot ringed by a dark halo during a routine map quality check. Space Daily reports the feature was absent before spring 2024, making it the largest newly formed crater recorded anywhere in the solar system.

People.com and Sci.News highlighted that the crater’s 222‑metre diameter surpasses the footprint of the Roman Colosseum, and FOX Weather described the event as a ‘once‑in‑a‑century’ asteroid impact. Future analyses aim to illuminate impact dynamics on airless bodies.
