The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using quantum-entangled Λ–anti-Λ pairs produced in J/ψ decays. The result improves the experimental sensitivity by about three orders of magnitude compared with the previous measurem

An international research team led by scientists from the Chinese Academy of Sciences (CAS) has discovered an isolated pulsar located within the tidal tail of NGC 6791, one of the oldest and most massive open clusters in the Milky Way. By combining observations from the Five-hundred-meter Aperture Spherical radio Telescope (FAST), the MeerKAT radio telescope and the Canada-France-Hawaii Telescope

In the vast cosmos, supernova explosions are widely regarded as the most brilliant fireworks in the universe. Among them, Type Ia supernovae (SNe Ia) are hailed as "standard candles" due to their highly consistent peak luminosity, making them a key tool for measuring cosmic distances. However, a recent study has found that even SNe Ia that appear nearly identical may hide small "genetic" differenc

Are the large-scale magnetic fields of magnetars dominated by a dipolar structure, or is a significant magnetic-field twist required to explain the observations? A recent study by researchers from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) has found that the observed X-ray polarization of two magnetars can be explained by dipole-dominated magnetic fields,

Active galactic nuclei (AGN), powered by accreting supermassive black holes, and X-ray binaries (XRBs), powered by accreting neutron stars or stellar-mass black holes, are two representative classes of compact accreting systems. Relativistic collimated jets are among the most spectacular phenomena in these systems. Understanding how these powerful outflows are launched, accelerated, and collimated

A research team from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences (CAS) has discovered that satellite galaxies retain a measurable "kinematic memory" of matter flowing into and along cosmic filaments. Using a large spectroscopic sample from the Sloan Digital Sky Survey (SDSS) , the team found that satellite galaxies preferentially orbit within planes that contain

The universe has been having fewer and fewer stellar "babies". Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for making stars has barely decreased. This finding comes from an international team led by researchers from the Chinese Academy of Sciences (CAS), in collaboration with the Dark Ene
