Keck Observatory observes first gravitationally lensed superluminous supernova
Astronomers have discovered the first-ever spatially resolved, gravitationally lensed superluminous supernova. The object, dubbed SN 2025wny, offers a rare look at a stellar cataclysm from the early Universe and provides a striking confirmation of Einstein’s theory of general relativity. The discovery relied on a chain of cutting-edge observatories collaborating on scientific breakthroughs.
Keck Observatory helps unravel mystery behind rare cosmic X-ray bursts
An international team of astrophysicists using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered a possible origin of fast X-ray transients (FXTs) — mysterious, fleeting bursts of X-rays that have long puzzled astronomers.
Astronomers: YR4 asteroid will not hit Earth in 2032, but has ~2% chance of moon strike
Despite being a scenario widely pondered by astronomers and Hollywood writers for decades, further observations have since determined YR4 will not impact the Earth in 2032 as originally predicted. However, there is a ~2% chance it could hit the Moon instead, according to the study.
