A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar ...

An international team of astronomers using a state-of-the-art receiver system on the 305-m Arecibo radio telescope in Puerto Rico has discovered a binary pulsar system which promises to be an ...

The pulsar is often compared to lighthouses because it emits beams of electromagnetic radiation that are pointed toward specific directions. A binary pulsar is a twin-star system made of a pulsar and ...

Researchers from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and their collaborators at home and abroad have discovered a binary pulsar with a 53-minute orbital ...

An international team of astronomers has spotted a binary pulsar that appears to behave very differently than most known binary systems in our galaxy. The most likely explanation, says the team, is ...

Pulsars are incredible heavenly bodies. They are neutron stars just 20 kilometers (12 miles) in diameter that pack more mass than our Sun. Their defining characteristic though is the beam of radio ...

Using the data obtained by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. PAN Zhichen and Prof. LI Di from the National Astronomical Observatories of ...

Binary pulsars—systems of two dead stars, at least one of which is a radiating pulsar—sit on a special pedestal in astronomy. The first discovery of such a system in 1974 also provided the first ...

In an interstellar race against time, astronomers have measured the warping of spacetime in the gravity of a binary star and determined the mass of a neutron star — just before it vanished from view.
