Wandering Black Hole in a Dwarf Galaxy

In our traditional view, black holes are usually thought to “reside” at the centers of galaxies. However, a recent study has discovered a wondering black hole in a dwarf galaxy about 230 million light-years away (redshift z = 0.017). Unlike ​the norm, this black hole is not located at the galactic center but is offset by nearly ...

"Mysterious Giant" Behind Binary Black Holes? Shanghai Astronomical Observatory Research Team Discovers First Evidence of a Third Compact Object!

The binary black holes in the universe are already astonishing enough, but researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences have made a groundbreaking discovery: these binary black holes may not be "lonely wanderers" after all—there could be an even more mysterious "giant" lurking behind th...

FAST Telescope Unveils Supersonic Filamentary Network in Very-High-Velocity Cloud

This discovery provides valuable new insight into how atomic gas behaves and organizes itself in the quieter, outer parts of our galaxy. It also deepens our understanding of how gas might eventually feed into star-forming regions, and what role such distant clouds might play in the broader life cycle of matter in galaxies.
