PSR B1919+21 PSR B1919+21 is a pulsar with a period of 1.3373 seconds and a pulse width of 0.04 seconds. Discovered by Jocelyn Bell Burnell and Antony Hewish on November 28, 1967, it is the first discovered radio pulsar. The power and regularity of the signals were briefly thought to resemble an extraterrestrial beacon, leading the source to be nicknamed LGM-1 (for "little green men").

Jocelyn Bell Burnell Dame Susan Jocelyn Bell Burnell, (born 15 July 1943) is a Northern Irish astrophysicist. As a postgraduate student, she discovered the first radio pulsars while studying and advised by her thesis supervisor Antony Hewish, for which Hewish shared the Nobel Prize in Physics with astronomer Martin Ryle. Bell Burnell was excluded, despite having been the first to observe and precisely analyse the pulsars. Bell Burnell was President of the Royal Astronomical Society from 2002 to 2004, president of the Institute of Physics from October 2008 until October 2010, and was interim president following the death of her successor, Marshall Stoneham, in early 2011. She was succeeded in October 2011 by Sir Peter Knight. Bell Burnell was elected as President of the Royal Society of Edinburgh in October 2014. In March 2013 she was elected Pro-Chancellor of the University of Dublin.

James Chadwick Sir James Chadwick, {'1': ", '2': ", '3': ", '4': "} (20 October 1891 – 24 July 1974) was an English physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during the Second World War. He was knighted in England in 1945 for his achievements in physics.

Martin Ryle Sir Martin Ryle FRS (27 September 1918 – 14 October 1984) was an English radio astronomer who developed revolutionary radio telescope systems (see e.g. aperture synthesis) and used them for accurate location and imaging of weak radio sources. In 1946 Ryle and Vonberg were the first people to publish interferometric astronomical measurements at radio wavelengths, although Joseph Pawsey from the University of Sydney claimed to have actually made interferometric measurements earlier in the same year. With improved equipment, Ryle observed the most distant known galaxies in the universe at that time. He was the first Professor of Radio Astronomy at the University of Cambridge, and founding director of the Mullard Radio Astronomy Observatory. He was Astronomer Royal from 1972 to 1982. Ryle and Antony Hewish shared the Nobel Prize for Physics in 1974, the first Nobel prize awarded in recognition of astronomical research.

7553 Buie 7553 Buie ( ), provisional designation 1981 FG, is a stony asteroid from the inner regions of the asteroid belt, approximately 3.5 kilometers in diameter. It was discovered on 30 March 1981, by American astronomer Edward Bowell at Lowell Observatory's Anderson Mesa Station in Flagstaff, Arizona. The asteroid was named after American astronomer Marc Buie.

Bargellini reaction The Bargellini reaction is a chemical reaction discovered in 1906 by Italian chemist Guido Bargellini (1879–1963). The original reaction was a mixture of the reagents phenol, chloroform, and acetone in the presence of a sodium hydroxide solution. Prior to Bargellini's research, the product attributed to this multi-component reaction (or MCR) had been described as a phenol derivative in chemistry texts at the time. However, Bargellini demonstrated that a carboxylic acid derivative was actually the correct structure.

Beethoven Burst (GRB 991216) GRB 991216, nicknamed the Beethoven Burst by Dr. Brad Schaefer of Yale University, was a gamma-ray burst observed on December 16, 1999, coinciding with the 229th anniversary of Ludwig van Beethoven's birth. A gamma-ray burst is a highly luminous flash associated with an explosion in a distant galaxy and producing gamma rays, the most energetic form of electromagnetic radiation, and often followed by a longer-lived "afterglow" emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, and radio).

Ada Hitchins Ada Florence Remfry Hitchins (26 June 1891 – 4 January 1972) was the principal research assistant of British chemist Frederick Soddy, who won the Nobel prize in 1921 for work on radioactive elements and the theory of isotopes. Hitchins isolated samples from uranium ores, taking precise and accurate measurements of atomic mass that provided the first experimental evidence for the existence of different isotopes. She also helped to discover the element protactinium, which Dmitri Mendeleev had predicted should occur in the periodic table between uranium and thorium.

Warwick Estevam Kerr Warwick Estevam Kerr (born September 9, 1922) is a Brazilian agricultural engineer, geneticist, entomologist, professor and scientific leader, notable for his discoveries in the genetics and sex determination of bees. The Africanized bee in the western hemisphere is directly descended from 26 Tanzanian queen bees ("A. m. scutellata") accidentally released by a replacement bee-keeper in 1957 in Rio Claro, São Paulo in the southeast of Brazil from hives operated by Kerr, who had interbred honey bees from Europe and southern Africa.

He was born in Edgerton, Wisconsin before completing high school in Los Angeles and was accepted in the University of California, Berkeley in 1901. He worked at the Mount Wilson Observatory from 1907 until 1948. He specialized in solar spectroscopy and mapped the distribution of magnetic fields over the Sun's surface. With his son he revealed the existence of strong magnetic fields in certain stars. In 1953 he won the Bruce Medal.
