 for their pioneering research in radio astrophysics, with special note made of Hewish's "decisive role" in the discovery of pulsarspulsar,

. In 1967, his research team observed that some radio sources in space were emitting signals, or pulses, at very regular intervals. It was soon determined that these pulsating stars, or pulsars, were neutron stars, whose presence in the universe had been postulated as early as the 1930s but not confirmed. The award to Hewish was controversial because a graduate student, Jocelyn Bell (Dame Susan Jocelyn Bell Burnell), and not Hewish himself, had been the first to identify a pulsating radio source.

Hewish, Antony


Born May 11, 1924, in Fowey, Cornwall. British astronomer. Fellow of the Royal Society of London (1968).

Hewish was educated at Cambridge University and became a professor there in 1971. He investigated the scintillation of radio sources that subtend a small angle and, independently of the Soviet astronomer V. V. Vitkevich, suggested that the outer layers of the solar corona could be investigated by studying the radio emissions of the Crab Nebula as they move through the corona. He headed the group of radio astronomers that discovered pulsars in 1967.

Hewish received a Nobel Prize in 1974.
