School Bus-Sized Asteroid 2026 JH2 to Pass Earth on May 18
NASA confirms that asteroid 2026 JH2, estimated at 16-35 meters across, will pass Earth at approximately 0.0006 astronomical units on May 18, 2026 . Discovered only days before its close approach by observatories including Mount Lemmon Survey in Arizona, the Apollo-type asteroid poses no impact threat but offers astronomers a rare opportunity to study newly detected near-Earth objects
. The asteroid is expected to brighten to magnitude 11.5 during closest approach, helping refine global asteroid-tracking systems

Methane Fingerprints Reveal Major Emissions in China, India, and Central Africa
A new study published in Nature Communications uses methane isotopologues to trace global emissions, revealing that East Asia (particularly China), South Asia (particularly India), and Central Africa show higher methane levels than previously estimated . Researchers combined satellite observations with ground-based measurements from 2019-2021, introducing a three-dimensional atmospheric modeling approach that better captures regional variability compared to traditional simplified models
. The study indicates global atmospheric methane levels have surged to record highs and are projected to increase by 13% by 2030

2024 Confirmed as Hottest Year in 175 Years of Records
The World Meteorological Organization reports that 2024 was the hottest year on record, with average global temperatures reaching 1.55°C (2.79°F) above the 1850-1900 baseline . This represents unprecedented climate warming and signals rapid progression toward potential climate disaster according to the latest WMO assessment
. The report documents record-breaking climate extremes across the planet

Humans Returned to Britain 500 Years Earlier Than Previously Thought
New evidence reveals that humans returned to Britain approximately 15,200 years ago, around 500 years earlier than previously believed, following the last ice sheet's retreat . Researchers analyzing fossil pollen, chironomids, and lake sediment chemical signatures discovered that Britain experienced an earlier climate warming phase than other northwest European regions
. Summer temperatures in Britain jumped from 5-7°C to 10-14°C roughly 15,200 years ago, enabling human tracking of reindeer and horse herds across warming landscapes

University of Cincinnati Student Contributes to Exoplanet Discovery 901 Light Years Away
A University of Cincinnati student has made collaborative discoveries about a Jupiter-like gas giant exoplanet located 901 light years away using telescope observations. The research has been highlighted by multiple science outlets for its contributions to exoplanet research. The findings add to humanity's understanding of distant planetary systems and the diversity of worlds beyond our solar system.
