1 Μαρ 2013 · The first explicit prediction of neutron stars was made by Walter Baade and Fritz Zwicky at Caltech in December 1933, nearly two years after the discovery of the neutron, in trying to explain the enormous energy released in supernova explosions.

In 2003, Marta Burgay and colleagues discovered the first double neutron star system where both components are detectable as pulsars, PSR J0737−3039. [100] The discovery of this system allows a total of 5 different tests of general relativity, some of these with unprecedented precision.
Neutron star [] The remains of high-mass stars, neutron stars are best characterized by their immense density. They have a mass of up to 3 solar masses, yet are only a few kilometers in diameter, hence their density.
History. In 1920, Arthur Eddington proposed that stars obtained their energy from nuclear fusion of hydrogen to form helium and also raised the possibility that the heavier elements are produced in stars.
4 Μαρ 2020 · Now, after decades of speculation, researchers are getting closer to solving the enigma, in part thanks to an instrument on the International Space Station called the Neutron Star Interior...
23 Οκτ 2024 · The discovery of pulsars in 1967 provided the first evidence of the existence of neutron stars. Pulsars are neutron stars that emit pulses of radiation once per rotation. The radiation emitted is usually radio waves, but pulsars are also known to emit in optical, X-ray, and gamma-ray wavelengths.
A special kind of neutron star, known as a pulsar, emits periodic—or repeating—bursts of radio waves, X-rays and gamma rays. The first pulsar was discovered in 1967 by Cambridge University researchers Jocelyn Bell Burnell and Anthony Hewish—though their existence had been predicted more than three decades earlier by Fritz Zwicky and others.
