description Antony Hewish Overview

Antony Hewish (1924-2021) was a British radio astronomer at Cambridge University who shared the 1974 Nobel Prize in Physics with Martin Ryle. In 1967, his research group at the Mullard Radio Astronomy Observatory observed the first pulsars, rapidly rotating neutron stars that emit regular radio pulses. The discovery was made using the Interplanetary Scintillation Array, and the signals were first identified by his graduate student Jocelyn Bell Burnell. Hewish's subsequent research focused on radio astronomy and astrophysics.

help Antony Hewish FAQ

Who shared the 1974 Nobel Prize in Physics with Antony Hewish?

Antony Hewish shared the 1974 Nobel Prize in Physics with fellow British radio astronomer Martin Ryle. They received the award for their pioneering research in radio astrophysics, particularly the discovery of pulsars.

What was Antony Hewish's role in the discovery of the first pulsar?

Antony Hewish supervised the research project that led to the discovery of the first pulsar, PSR B1919+21, in 1967. His graduate student Jocelyn Bell Burnell was the first to notice the anomalous radio signal, but Hewish received the Nobel recognition for the work.

What kind of telescope did Antony Hewish use to discover pulsars?

Hewish used the Interplanetary Scintillation Array, a massive radio telescope constructed at the Mullard Radio Astronomy Observatory near Cambridge. This specialized array of wooden poles and wires was originally designed to track quasars by observing their radio scintillation.

Why didn't Jocelyn Bell Burnell share the 1974 Nobel Prize with Antony Hewish?

Jocelyn Bell Burnell did not share the 1974 Nobel Prize with Antony Hewish, a decision that sparked significant controversy in the scientific community. Although Bell made the initial observation, the Nobel committee historically awarded the prize to the supervising principal investigator.
