Today's topics:

Once-in-century lunar impact - NASA’s Lunar Reconnaissance Orbiter team has confirmed McGetchin, a newly formed lunar crater and the largest fresh impact crater yet discovered in the Solar System. The rare event offers scientists a valuable look into the Moon’s shallow subsurface, thermal behavior, and impact hazards. Keywords: McGetchin crater, Lunar Reconnaissance Orbiter, lunar impact, Moon science, cold spot.

Ghosts of five supernovas - NASA’s Astronomy Picture of the Day highlights a haunting composite view of five overlapping supernova remnants. The image shows how ancient stellar explosions shape the interstellar medium and recycle heavy elements across the galaxy. Keywords: supernova remnants, APOD, stellar explosions, interstellar medium, galaxy evolution.

Weird early-universe galaxies - Hubble observations from the TEMPOS survey show that extremely metal-poor O-type stars in nearby galaxies may mimic the stars that shaped the early Universe. These powerful stars help explain why young galaxies looked chaotic and evolved so quickly. Keywords: TEMPOS survey, Hubble, metal-poor stars, early Universe, galaxy formation.

China’s new Yaogan satellites - China has launched the Yaogan-40 04 remote-sensing satellite group aboard a Long March-6A rocket from Taiyuan. The mission supports electromagnetic environment detection and reflects China’s continued growth in space-based sensing capabilities. Keywords: Yaogan-40 04, Long March-6A, China launch, remote sensing, space surveillance.

SpaceX readies orbital Starship - SpaceX has stacked a Starship upper stage on a Super Heavy booster at Starbase ahead of Flight 14. The mission is expected to test orbital operations and potentially deploy next-generation Starlink V3 satellites, pending regulatory approval. Keywords: Starship Flight 14, SpaceX, Super Heavy, orbital test, Starlink V3.

Neptune near opposition tonight - Neptune is near opposition and well placed for evening observers in Pisces. Skywatchers with binoculars or small telescopes can look for the distant ice giant’s subtle gray-blue disk against a nearby background star. Keywords: Neptune opposition, Pisces, skywatching, amateur astronomy, outer planets.

AI-driven spacecraft docking - Stanford engineers have proposed an AI-based docking method that uses internal simulated scenarios to plan spacecraft maneuvers. The approach could improve autonomous rendezvous safety and adaptability for future orbital missions. Keywords: AI docking, spacecraft autonomy, Stanford, rendezvous, orbital operations.

Growing tension over space weapons - China has warned that acknowledged U.S. on-orbit space weapons could trigger a wider arms race in space. The dispute highlights growing concern
