Extractions: (b. May 11, 1924, Fowey, Cornwall, Eng.), British astrophysicist who won the Nobel Prize for Physics in 1974 for his discovery of pulsars (cosmic objects that emit extremely regular pulses of radio waves). Hewish was educated at the University of Cambridge and in 1946 joined the radio astronomy group there led by Sir Martin Ryle . While directing a research project at the Mullard Radioastronomy Observatory at Cambridge in 1967, Hewish recognized the significance of an observation made by a graduate assistant, Jocelyn Bell. He determined that the regularly patterned radio signals, or pulses, that Bell had detected were not caused by earthly interference or, as some speculated, by intelligent life forms trying to communicate with distant planets but rather were energy emissions from certain stars. For this work in identifying pulsars as a new class of stars, he was awarded jointly with Ryle the Nobel Prize for Physics in 1974, the first time the prize had been given for observational astronomy. Hewish was professor of radio astronomy at the Cavendish Laboratory, Cambridge, from 1971 to 1989.

Extractions: While pursuing her PhD at Cambridge University, Jocelyn Bell 's advisor was Antony Hewish, a radio astronomer. Hewish and his graduate students in 1967 completed a radio telescope specially designed to observe the scintillation (twinkling) of stars, particularly quasars. That summer, they observed an unusual signal at a wavelength of 3.7m unusual in that it corresponded to a sharp burst of radio energy at a regular interval of about one second. These were not like signals from other known sources such as stars, galaxies, or solar wind. Bell realized that the unusual reading, "scruff" as she called it, was regular (every 1.3373011 seconds) and synchronized with sidereal (star) time and not Earth time. That insight, plus the ruling out of various earthbound sources such as pirate radio and police transmissions, suggested that the signal was extraterrestrial. Might it be a message sent by intelligent beings from another world? They couldn't rule out "little green men" at this point, and they half-kiddingly named the signal LGM1. But that left them with a dilemma: Who could they tell? And what would they say? Bell and Hewish kept tracking their discovery and before they felt they had to announce the find to anyone, Bell found another pulsing signal. Only this one was slightly different it pulsed at 1.2 second intervals. And it came from the other side of the sky. These two differences made it extremely unlikely that the source was intelligent beings.

The discovery by Jocelyn Bell Burnell of a regularly fluctuating signal, which turned out to be the first pulsar, began a period of intensive research. Hewish discovered another three straight away, and more than 170 pulsars have been found since 1967.

Extractions: Before 1950, Hewish used radio telescopes mainly to study the solar atmosphere. When new instruments became available, radio observations were extended to sources other than the Sun. Before the discovery of pulsars, Hewish examined the fluctuation in such sources of the intensity of the radiation (the scintillation) resulting from disturbances in ionized gas in the Earth's atmosphere, within the Solar System, and in interstellar space.

A pulsar , which originally stood for pulsating radio source , is a rapidly rotating neutron star A neutron star is a compact star in which the weight of the star is carried by the pressure of free neutrons. It is a so called degenerate star. The neutron is an elementary particle and one of the building blocks of atomic nuclei. Neutrons are electrically neutral (hence the name) and in contrast to protons, can be packed to form extremely large "nuclei", up to several times the mass of the Sun. Neutron stars are the first major astronomical object whose existence was first predicted from theory (1933) and later (1968) found to exist, at first as radio pulsars.

Light is a form of electromagnetic radiation. The theoretical study of electromagnetic radiation is called electrodynamics, a subfield of electromagnetism.
