FAST Joins MeerKAT: Unveiling the Pristine Nature of Ancient Galactic Systems
In a milestone of international astronomical collaboration, Prof. Di Li's team at Tsinghua University, along with institutions in Italy, Australia, and Germany, have completed a high-precision polarization census of pulsars in globular clusters, utilizing the combined power of the FAST radio telescope in China and the MeerKAT array in South Africa. This study marks the first in-depth cooperatio...

New Study Reveals Hidden Population of Cold, Rocky Planets
Super-Earth exoplanets—worlds slightly larger than Earth—are common in the outer regions of planetary systems, where gas giants like Jupiter are typically found. A new international study, published today in Science, adds an important piece to the puzzle of planetary system formation by highlighting a previously underexplored population of cold, rocky planets orbiting far from their stars.“W...

Pre-release of CRAFTS Wide-band Spectral Line Data Cube
The Commensal Radio Astronomy FasT Survey (CRAFTS; Li et al. 2018) is one of the Five-hundred-meter Aperture Spherical radio Telescope (FAST) key projects. CRAFTS simultaneously records wide-band spectral line data, narrow-band spectral line data, and high temporal resolution time-domain data, enabling diverse scientific objectives. The wide-band spectral line data cover a spectral window in th...

Tsinghua Astronomers found the correlation between stellar metallicities and planet mutual inclinations
Our Solar System exhibits a flat architecture, with nearly all planets orbiting within the same plane. Among them, Mercury is the most inclined planet with a mutual inclination of 7 degrees relative to Earth’s orbital plane (Figure 1). Mutual inclination, which refers to the angle between the orbital planes of two planets, serves as a key indicator of the dynamical architecture of planetary sy...
