  • Scientists Discover First Clear Observation of Disk-Jet Co-precession in Tidal Disruption Event

    A research team led by the National Astronomical Observatories of the Chinese Academy of Sciences, in collaboration with international partners, has released the strongest evidence to date of disk-jet co-precession in the TDE known as AT2020afhd—a long-predicted outcome of spacetime dragging caused by a spinning black hole.

  • Physicists Provide Key Mass Data for Determining X-ray Burst Reaction Rate

    A research team from the Institute of Modern Physics has directly measured the masses of two highly unstable atomic nuclei, phosphorus-26 and sulfur-27. These precise measurements provide crucial information for determining the nuclear reaction rate during X-ray bursts, advancing our understanding of how elements are synthesized under such extreme conditions.

  • Scientists Uncover How Earth's Mantle Locked Away Vast Water in Early Magma Ocean

    A team of researchers led by Prof. DU Zhixue from the Guangzhou Institute of Geochemistry of the Chinese Academy of Sciences has discovered that substantial amounts of water could have been efficiently "locked away" deep within the mantle as it crystallized from a molten state.

  • Researchers Develop Novel Bathymetric Framework for High-Accuracy Shallow-Water Mapping

    A research team led by Prof. NIE Sheng from the Aerospace Information Research Institute of the Chinese Academy of Sciences has developed a new bathymetric mapping framework. This framework integrates the indirect inversion of land Elevation Satellite-2 (ICESat-2) LiDAR data with multi-source remote sensing observations. By combining wave-based indirect bathymetry, multi-source feature fusion, and a temporal sample-transfer strategy, it achieves high-accuracy, wide-coverage mapping in optically complex shallow waters.
