Destroying Asteroid 2024 YR4 Is The Best Option To Stop It From Hitting The Moon
arXiv:2509.12351v1 Announce Type: new Abstract: Near-Earth asteroid 2024 YR4 was discovered on 2024-12-27 and its probability of Earth impact in December 2032 peaked at about 3% on 2025-02-18. Additional observations ruled out Earth impact by 2025-02-23. However, the probability of lunar impact in December 2032 then rose, reaching about 4% by the end of the apparition in May 2025. James Webb Space Telescope (JWST) observations on 2025-03-26 estimated the asteroid's diameter at 60 +/- 7 m. Stu...
Black Hole Merger Provides Clearest Evidence Yet that Einstein, Hawking, and Kerr were Right
When two black holes collide and merge, they release gravitational waves. These waves can be detected by sensitive instruments on Earth, allowing scientists to determine the mass and spin of the black holes. The clearest black hole merger signal yet, named GW250114 and recorded by LIGO in January 2025, offers new insights into these mysterious objects.
It's Official. We Now Know Of 6,000 Confirmed Exoplanets
