Extractions: The real story behind the discovery of pulsars by astronomer Jocelyn Bell with JOCELYN BELL BURNELL Interactive Timeline of Space Discovery True, the movie Contact features the giant dish antennae radio telescopes and not the type (a field of wires) built by Jocelyn and fellow students from a design by Antony Hewish, her advisor. And the location was switched from Cambridge, England to the deserts of Socorro , New Mexico. What was the source of these signals? Was it an orbiting satellite? Radar? Or possibly French TV signals bouncing across the English Channel? The signals occurred 4 minutes earlier each evening just like the stars rising in the sky. With the earthly possibilites ruled out, Hewish even considered "little green men" from outer space who were trying to reach us by radio. The press went wild.

But how else could she explain those tiny squiggles coming from her chart recorder? Bell, in charge of the telescope, was making observations toward her Ph.D. Bell decided she needed more detail on the odd blips, so she installed a faster chart recorder (this was before the age of ubiquitous computers) to get a clearer picture. For two months nothing showed up. Then the mysterious signal reappeared. The new recorder showed that the radio pulses were coming at an unvarying interval of 1.33 seconds. Exactly every one point three three seconds, with not a fraction of variance. Logic dictated that if the signals were indeed artificial, they must be coming from intelligent aliens. Little green men. Bell dubbed the source LGM-1 (the first little green men signal) and continued her observations while she, Hewish and the others debated how to announce their discovery. They didnt really believe the signals were coming from aliens, but they were at a loss for any natural explanation. And then Bell found another source, and soon another, and another, all in different parts of the sky and all showing the same regularity (but with slightly different periods). It seemed very unlikely that four groups of aliens were all broadcasting at the same frequency. Bell and Hewish quickly dropped the LGM hypothesis.

Extractions: 1) Pulsars are phenomenal objects: rapidly rotating neutron stars that send out beams of radio waves which, like lighthouse beams, sweep around the sky as the star rotates. They are amazingly precise timing devices that can be used as clocks for testing relativity theory and may be used for timekeeping and navigation. With a diameter of only about 15 kilometers and a density comparable to that of the nucleus of an atom, they also provide a laboratory for some extreme physics. 2) In the fall of 1967, I was conducting a routine mapping project studying the radio scintillation of quasars for my doctoral thesis at Cambridge University, under the direction of my adviser, Antony Hewish. Investigation of a puzzling weak signal showed it to be a string of pulses, 1.33 seconds apart. We spent a month trying to find out what was wrong, so unexpected was the signal; and we nicknamed it "Little Green Men" (LGM). At the end of that month, I found a second pulsar, killing the LGM hypothesis and indicating a new kind of astronomical source.

Extractions: We had a hundred feet of chart paper every day, seven days a week, and I operated it for six months, which meant I was personally responsible for quite a few miles of chart recording. It was four hundred feet of chart paper before you got back to the same bit of sky, and I thought-having had all these marvelous lectures as a kid about the scientific method-that this was the ideal way to do science. With that quantity of data, no way are you going to remember what happened four hundred feet ago. You're going to come to each patch of sky absolutely fresh, and record it in a totally unbiased way. But actually, one underestimates the human brain. On a quarter inch of those four hundred feet, there was a little bit of what I call "scruff," which didn't look exactly like [quasar] scintillation....After a while I began to remember that I had seen some of this unclassifiable scruff before, and what's more, I had seen it from the same patch of sky. The 81.5-megahertz radio signal was emanating from a spot midway between the stars Vega and Altair. A higher-speed recording revealed that the signal was actually a precise succession of pulses spaced 1.3 seconds apart. The unprecedented clocklike beeps caused Hewish and his group to label the source LGM for "Little Green Men." This was done only half in jest. At one point some consideration was given to the possibility that the regular pulsations were coming from a beacon set up by an extraterrestrial civilization. Within a month Bell ferreted out, from the yards upon yards of strip chart that were spewing from the telescope, the telltale markings of a second suspicious source. Its period was 1.19 seconds. By the beginning of 1968, two more were uncovered. When the phenomenon was announced to the public, a British journalist dubbed the freakish sources pulsars.

Extractions: Jocelyn Bell Burnell Can You Believe It? When they were not sure what caused the signals they detected, Jocelyn Bell and her college advisor D. Anthony Hewish labeled the signal LGM for Little Green Men. They thought it could possibly be a beacon from an alien source. Susan Jocelyn Bell was born in Belfast, Northern Ireland on July 15, 1943. Her father was an architect and an avid reader. Through his books, Jocelyn was introduced to the world of astronomy. Her family and the staff of the Armagh Observatory, which was near her home in Belfast, encouraged her interest in astronomy. Jocelyn Bell's parents very strongly believed in educating women. When she failed the examination required for students wanting to pursue higher education in British schools, they sent her to a boarding school to continue her education. In 1965, Jocelyn Bell earned a B.S. degree in physics from the University of Glasgow. Later that same year she began work on her Ph.D. at Cambridge University. It was while she was a graduate student at Cambridge, working under the direction of Antony Hewish, that Jocelyn Bell discovered pulsars.

Extractions: Home Overview Events Archives ... Committee Prof Antony Hewish FRS Pulsar Physics Wednesday 16.2.05; Old Combination Room , 8 p.m. Pulsars are stars as massive as the Sun with interior densities exceeding 100 million tonnes per cubic cm and typical magnetic fields of 100 million Teslas. Spinning at up to 600 revs per sec they emit coherent, beamed radiation. Understanding how they behave, and how they can be used to test general relativity involves some interesting physics. Background Resources Professor Hewish is a radio astronomer who was awarded, with Martin Ryle, the Nobel Prize for Physics 1974 for his work on pulsars (rapidly rotating neutron stars that emit pulses of energy). 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. Professor Hewish discovered another three straight away, and more than 170 pulsars have been found since 1967. He was born in Cornwall and was educated at Cambridge. In 1946, he joined the radio astronomy group led by Sir Martin Ryle. While directing a research project at the Mullard Radioastronomy Observatory 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.
