Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have conducted single-pulse observations of a pulsar known as PSR B1929+10. Results ...
Scientists observed what appears to be a bulked-up black hole tangling with a more ordinary one. The research team, which includes physicists from the University of Maryland, detected two black holes merging, but one of the ...

Using NASA's Fermi and Swift spacecraft, astronomers have investigated SGR J1935+2154, the most recurring transient magnetar known to date. The new research sheds more light on the burst properties of this object. The study ...
Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force—one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force. The strong nuclear ...
