Derrick H. Pitts is an American astronomer.
 He is Chief Astronomer and Planetarium Director for the Franklin Institute in Philadelphia, Pennsylvania.
 He has been named as one of the 50 most important African-Americans in research science.
 He was the president of the Philadelphia chapter of the Tuskegee Airmen, Inc.
 He has made numerous television appearances, including shows such as "The Colbert Report", "The Late Late Show with Craig Ferguson", "Countdown with Keith Olbermann," "The Last Word with Lawrence O'Donnell," and "The Ed Show".
 He co-hosts a weekly radio discussion program called "Skytalk" on WHYY-FM in Philadelphia, PA.
Franklin Evans Roach (September 23, 1905 – September 21, 1993) was an American astronomer, astrophysicist, geophysicist, professor, and scientist analyzing UFO phenomenon who made significant contributions to the field of aeronomy in upper atmosphere research as one of its fathers.
 Roach was involved in high explosives physics research connected with the Manhattan Project and later with NICAP and the Condon Committee as part of ufology.
Steven J. Dick (born October 24, 1949, Evansville, Indiana) is an American astronomer, author, and historian of science most noted for his work in the field of astrobiology.
 Dick served as the Chief Historian for the National Aeronautics and Space Administration from 2003 to 2009 and as the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology from 2013 to 2014.
 Before that, he was an astronomer and historian of science at the United States Naval Observatory in Washington, DC, from 1979 to 2003.
Douglas C. Prasher (born August 1951) is an American molecular biologist.
 He is known for his work to clone and sequence the genes for the photoprotein aequorin and green fluorescent protein (GFP) and for his proposal to use GFP as a tracer molecule.
 He communicated his pioneering work to Martin Chalfie and Roger Y. Tsien, but by 1991 was himself unable to obtain further research funding, and left academia.
 Eventually, he had to abandon science.
 Chalfie and Tsien were awarded the 2008 Nobel Prize in Chemistry for work that they publicly acknowledged was substantially based on the work of Douglas Prasher, and through their efforts and those of others, Douglas Prasher was returned to scientific research work in June 2010.
Seth Shostak (born July 20, 1943) is an American astronomer, currently Senior Astronomer for the SETI Institute and former Director of Center for SETI Research when it was a separate department.
The Newton Lacy Pierce Prize in Astronomy is awarded annually by the American Astronomical Society to a young (less than age 36) astronomer for outstanding achievement in observational astronomical research.
 The prize is named after Newton Lacy Pierce, an American astronomer.
Robert Woodrow Wilson (born January 10, 1936) is an American astronomer, 1978 Nobel laureate in physics, who with Arno Allan Penzias discovered in 1964 the cosmic microwave background radiation (CMB).
 The award purse was also shared with a third scientist, Pyotr Leonidovich Kapitsa, for unrelated work.
Frederick Charles Leonard (March 12, 1896 – June 23, 1960) was an American astronomer.
 As a faculty member at the University of California, Los Angeles, he conducted extensive research on double stars and meteorites, largely shaping the university's Department of Astronomy.
 He received his undergraduate degree from the University of Chicago in 1918 and his PhD in astronomy from the University of California, Berkeley in 1921.
 Leonard was an astronomer from his teenage years, founding the Society for Practical Astronomy in 1909.
 In 1933 he founded The Society for Research on Meteorites, which later became known as the Meteoritical Society.
 He was its first president and was the Editor of the Society's journal for the next 25 years.
 The Society instituted the Leonard Medal in 1962, its premier award for outstanding contributions to the science of meteoritics and closely allied fields.
The Holmdel Horn Antenna is a large microwave horn antenna that was used as a radio telescope during the 1960s at Bell Telephone Laboratories in Holmdel Township, New Jersey, United States.
 It was designated a National Historic Landmark in 1988 because of its association with the research work of two radio astronomers, Arno Penzias and Robert Wilson.
 In 1965 while using this antenna, Penzias and Wilson discovered the microwave background radiation that permeates the universe.
 This was one of the most important discoveries in physical cosmology since Edwin Hubble demonstrated in the 1920s that the universe was expanding.
 It provided the evidence that confirmed George Gamow's and Abbe Georges Lemaitre's "Big Bang" theory of the creation of the universe.
 This helped change the science of cosmology, the study of the history of the universe, from a field for unlimited theoretical speculation into a discipline of direct observation.
 In 1978 Penzias and Wilson received the Nobel Prize for Physics for their discovery.
Donald B. Campbell is an Australian-born astronomer and Professor of Astronomy at Cornell University.
 Prior to joining the Cornell faculty he was Director of the Arecibo Observatory in Puerto Rico for seven years.
 Campbell's research work is in the general area of planetary studies with a concentration on the radio-wavelength-scattering properties of planets, planetary satellites, and small bodies.
 His work includes studies of Venus, the Moon, the Galilean satellites of Jupiter, Titan, as well as comets and asteroids.
 Campbell observed near-Earth asteroid 433 Eros, which was the first asteroid detected by the Arecibo Observatory radar system.
