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,

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

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

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

Ahead of the scheduled Aug. 30 launch of NASA’s Nancy Grace Roman Space Telescope, several Washington University in St. Louis researchers have been selected to play important roles in the mission’s inaugural science program. The Roman telescope promises to transform our understanding of the universe. NASA will use the Roman telescope to investigate dark energy, discover thousands of exoplanets and

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

Galaxy mergers are among the most spectacular and destructive events in the universe. During these encounters, not only are billions of stars redistributed, but the supermassive black holes lurking in the galaxies' centers can also interact with one another. Yet systems where three galaxies merge simultaneously are uncommon. Now, researchers have obtained the first direct observational evidence fo

The NSF-DOE Vera C. Rubin Observatory marked a major milestone with the beginning of the Legacy Survey of Space and Time (LSST), a 10-year effort to capture the universe in unprecedented detail. Lawrence Livermore National Laboratory (LLNL) engineer and former project manager for the LSST Camera, Vincent Riot reflected on the culmination of the project and the journey ahead. Development of the world's largest digital camera began before Riot arrived at the Lab in 2003. For most of his career, he worked to build first-of-its kind optical components, including lenses that would later be
