Junggar basin sediments reveal interplay between Solar System chaos and Earth’s carbon cycle
Chinese Academy of Sciences HeadquartersPeer-Reviewed Publication
Researchers from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences and Columbia University, along with their collaborators, have analyzed sediments from the terrestrial Sangonghe Formation (Late Early Jurassic) in China's Junggar Basin, revealing information both on Solar System chaos and the global carbon cycle.

LHAASO unveils galactic treasure map: breakthroughs in ultra-high-energy gamma-ray astronomy
Science China PressPeer-Reviewed Publication
This collection of four pioneering studies showcases the transformative capabilities of the Large High Altitude Air Shower Observatory (LHAASO), whose unmatched sensitivity (>100 TeV) and hybrid detector system (KM2A/WCDA) are redefining ultra-high-energy (UHE) gamma-ray astronomy. Key breakthroughs include: (1) Identifying young star-forming region W43 as a Galactic cosmic-ray accelerator (up to hundreds of TeV), evidenced by extended emission coinciding with dense gas and OB stars; (2) Resolving particle acceleration to 300 TeV within the pulsar wind nebula (PWN) of composite SNR CTA1, revealing advection-dominated transport under ≈4.5 μG magnetic fields; (3) Detecting extended VHE emissions around pulsar J0248+6021, providing critical insights into PWN-to-halo evolutionary transitions; and (4) Unraveling the mysterious UHE source J0056+6346u, potentially powered by hidden pulsars or SNR candidate. These results leverage LHAASO's exceptional detector performance to constrain both particle transport dynamics and extreme acceleration mechanisms across the 1 TeV–1 PeV energy range. LHAASO is ushering in a new era of UHE astrophysics, bringing us closer than ever to solving century-old cosmic-ray mysteries.

European high school students emerge from isolation after groundbreaking explore analog space exploration mission
International Science Council Committee on Space ResearchBusiness Announcement
MONSARAZ, PORTUGAL – 30 June 2025 – The silence was broken by cheers and the snap of camera shutters as nine European high school students stepped out of a simulated Mars environment in Portugal, successfully completing the first-of-its-kind EXPLORE analog mission. From 23 to 27 June 2025, these students from Austria, Greece, and Portugal traded their everyday lives for a challenging five-day immersion in an isolated, Mars-like landscape near Monsaraz, in the wilds of the Alentejo province.
