An illustration of the 14 pairs of binary pulsars used to measure our galactic acceleration. In a new study just published here in early 2021, the orbital periods and changes in the orbital periods of ...

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 ...

This aerial photo taken on June 22, 2023 shows China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) under maintenance in southwest China's Guizhou Province. China's FAST telescope ...

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 ...

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 ...

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 ...

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 ...

The general theory of relativity is a remarkably successful model for gravity. However, many of the best tests for it don't push its limits: they measure phenomena where gravity is relatively weak.

Using the Australian SKA Pathfinder (ASKAP) telescope, astronomers have discovered a new millisecond pulsar (MSPs) at a ...

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 ...

Black widow binary consists of a rapidly spinning neutron star, or pulsar, that is circling and slowly consuming a smaller companion star (Nasa) Astronomers have observed what appears to be a rare ...
