Burbidge's career in astrophysics spanned several decades and institutions. Burbidge's scientific contributions primarily focused on nuclear astrophysics, the internal structure and evolution of stars, the physics of galaxies, and quasars. Her groundbreaking research with William Fowler and Fred Hoyle established the fundamental role of nuclear reactions in stars in the formation of heavy elements.

She also studied galaxies, determining their masses, chemical and stellar compositions, and exploring their unusual characteristics. In the s, Burbidge and her husband were among the first to investigate quasars. They obtained spectra of numerous quasars and measured their redshifts. Her work extended to the theory of radiation emitted by radio galaxies, quasars, and pulsars.

On earth, we see the released energy as starlight. Burbidge went on to argue that as stars mature they burn off some of their helium, producing other elements, such as oxygen and carbon.

Oxygen and carbon may then trap hydrogen, which creates complex elements, such as silicon, argon, magnesium, sulphur, and calcium. Margaret pointed to three other processes that may occur. One is the e-process, in which iron, cobalt, chromium, and nickel are formed due to extreme heat. When the "iron-peak" is reached, energy from the star is released.

Beyond this point, additional energy is required to produce heavier elements. When an exploding star occurs, such as a supernova, the required amount of energy is released. Burbidge also identified the r-process, in which the newly formed nuclei ensnare neutrons and are able to shed electrons. The resulting explosion produces elements such as bromine, krypton, selenium, xenon, tellurium, iridium, iodine, uranium, gold, and platinum.

Margaret Burbidge's calculations provided a theoretical framework for measuring the production of different heavy elements in a supernova. She also theorized that a slower process, the s-process, also creates heavy elements in red giants. Her research into quasars established that the ultraviolet radiation given off is the result of quasars receding at a great speed.

This creates a spectrum shift towards red light, so that only a weak blue light is visible from the earth. During her research, she also discovered objects with red shifts, but no ultraviolet radiation. The Burbidges dubbed these quasi-stellar objects. Subsequent research by Margaret revealed that quasars and galaxies are intimately connected.

Quasars tend to be located at the opposite end of bright galaxies, thus suggesting a yet to be determined dependent relationship, but one that put into question the Big-Bang Theory. InMargaret Burbidge took a leave of absence as chair of astronomy at the University of California and returned to England, where she succeeded Sir Richard Woolley as the first female director of the Royal Greenwich Observatory.

The circumstances of the appointment, however, were far from ideal. Tradition dictated that the positions of the director of the Royal Greenwich Observatory and that of Astronomer Royal be held concurrently. While Woolley retired as director of the observatory inhe retained the title of Astronomer Royal. Although the staff of the Royal Greenwich Observatory protested to both the secretary of state for education and science, and to Prime Minister Margaret Thatcherno action by the British government was taken to remedy the situation.

On November 18,Margaret Burbidge held a news conference in London. As The Times of London reported:. This attractive middle-aged woman brings to the job a charm not usually associated with the realms of advanced astronomy. Whether this factor, added to her reputation, will be enough to steer her through some difficult times ahead is an open question.

Burbidge made it clear during the news conference that gender bias was at the heart of the decision to exclude her from the position of Astronomer Royal. She argued that men and women should by treated equally in the field of astronomy. What should have been one of the crowning achievements of her career thus became another example of the discrimination she faced.

Burbidge promised to focus her energies on research, rather than allowing administrative duties to consume her time. It had taken considerable effort on the part of the Science Research Council to persuade Burbidge to return to Great Britain. She had arrived with the understanding that she would work to revive optical astronomy in the British Isles.

The field, however, was in disarray. In an article entitled "Scandalous Muddle in British Astronomy," published in Natureher husband Geoffrey argued that optical astronomy in Britain was on its death bed. He then catalogued a eleanor margaret burbidge biography of rory list of errors that had led to the departure of elite astronomers from Britain over the years, including the Burbidges.

In the article, Geoffrey reported that radioastronomy and theoretical astronomy were on a sound footing. Years of underfunding and neglect, however, had rendered optical astronomy third rate. Major mistakes, he alleged, included the mis-sighting of the Isaac Newton Telescope, Britain's largest. The mistake rendered the instrument virtually useless, contended Geoffrey.

Other errors in judgment, such as the failure of Britain to join the European South Observatory Project, had left British astronomy far behind international efforts. While Europeans, Americans, Canadians, and Russians were all building observatories in northern Chile, British astronomers had failed to grasp the observational opportunities that the Chilean site presented.

Instead, the British Government decided to build a large Schmidt telescope jointly with Australia. The decision was condemned by Geoffrey, due to the poor observational conditions of the site. Margaret subsequently echoed many of the same concerns, though her position at the time precluded her from voicing these opinions as forcefully.

From toMargaret Burbidge served on the Anglo-Australian Telescope Board and advocated a management strategy common to major observatories around the world. It was rejected by the board, largely due to its American origins. As well, Burbidge sat on the board when the Australian National Universitya major participant in the project, attempted to seize control of the observatory.
