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...
Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars, and the discovery of pulsars by Jocelyn Bell Burnell and Antony Hewish in 1967 was the first observational suggestion that neutron stars exist.
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.
Ernest Rutherford (1871–1937) postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908.
23 Οκτ 2024 · Ernest Rutherford, British physicist who discovered that the atom is mostly empty space surrounding a massive nucleus and who did many pioneering experiments with radioactivity. He was also known for predicting the existence of the neutron and calculating Avogadro’s number.
29 Ιουλ 2023 · Explain the research method that led to the discovery of neutron stars, located hundreds or thousands of light-years away. Describe the features of a neutron star that allow it to be detected as a pulsar. List the observational evidence that links pulsars and neutron stars to supernovae.
The Discovery of Neutron Stars. In 1967, Jocelyn Bell, a research student at Cambridge University, was studying distant radio sources with a special detector that had been designed and built by her advisor Antony Hewish to find rapid variations in radio signals. The project computers spewed out reams of paper showing where the telescope had ...
