The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.
About 5% of all known neutron stars are members of a binary system. The formation and evolution of binary neutron stars [75] and double neutron stars [76] can be a complex process. Neutron stars have been observed in binaries with ordinary main-sequence stars, red giants, white dwarfs, or other neutron stars. According to modern theories of ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope.

1964 – CP violation discovered by James Cronin and Val Fitch. 1965 – Arno Penzias and Robert Wilson: Cosmic Microwave Background (CMB) discovered; 1967 – Unification of weak interaction and electromagnetism (electroweak theory) 1967 – Solar neutrino problem found; 1967 – Pulsars (rotating neutron stars) discovered
Dame Susan Jocelyn Bell Burnell (/ b ɜːr ˈ n ɛ l /; née Bell; born 15 July 1943) is an astrophysicist from Northern Ireland who, as a postgraduate student, discovered the first radio pulsars in 1967. [9] [10] The discovery eventually earned the Nobel Prize in Physics in 1974; however, she was not one of the prize's recipients. [11]
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
Neutron star: Neutron stars are stellar remnants produced when a star of around 8–9 solar masses or more explodes in a supernova at the end of its life. They are usually produced by stars of less than 20 solar masses, although a more massive star may produce a neutron star in certain cases. [2] 4U 1820-30: 9.1 Pulsar [3] Lich Pulsar (PSR ...
