Clyde Tombaugh Clyde William Tombaugh ( ; February 4, 1906January 17, 1997) was an American astronomer. He discovered Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt. At the time of discovery, Pluto was considered a planet but was later reclassified as a dwarf planet in 2006. Tombaugh also discovered many asteroids. He also called for the serious scientific research of unidentified flying objects, or UFOs.

Vera Rubin Vera Cooper Rubin (July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. She uncovered the discrepancy between the predicted angular motion of galaxies and the observed motion, by studying galactic rotation curves. This phenomenon became known as the galaxy rotation problem, and was evidence of the existence of dark matter. Although initially met with skepticism, Rubin's results were confirmed over subsequent decades. Her legacy was described by "The New York Times" as "ushering in a Copernican-scale change" in cosmological theory.

Langley extrapolation Langley extrapolation is a method for determining the Sun's irradiance at the top of the atmosphere with ground-based instrumentation, and is often used to remove the effect of the atmosphere from measurements of, for example, aerosol optical thickness or ozone. It is based on repeated measurements with a sun photometer operated at a given location for a cloudless morning or afternoon, as the Sun moves across the sky. It is named for American astronomer and physicist Samuel Pierpont Langley.

Arthur Hoag Arthur Allen Hoag (1921–1999) was an American astronomer most famous for his discovery of Hoag's object in 1950. He was the son of Lynne Arthur Hoag (Harvard Medical School, Cornell, and University of Michigan faculty member) and wife Wylma Wood Hoag. He had two sisters, Mary Alice (born 1922) and Elizabeth Ruth (born 1919), a son named Tom and a daughter named Stefanie. His mother and sister Mary (aged 3) died on June 1, 1926 when the "Washington Irving" was rammed by an oil barge and sunk on the North River.

McMath–Hulbert Observatory The McMath-Hulbert Solar Observatory is a decommissioned solar observatory in Lake Angelus, Michigan, USA. It was established in 1929 as a private observatory by father and son Francis Charles McMath and Robert Raynolds McMath and their friend, Judge Henry Hulbert. In 1932 the observatory was deeded to the University of Michigan which operated it until 1981, at which time it was sold into private ownership again.

2940 Bacon 2940 Bacon, provisional designation 3042 P-L, is a carbonaceous Dorian asteroid from the central region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 24 September 1960, by Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at Palomar Observatory in California, United States. It was later named after English philosopher and statesman Francis Bacon.

Voyager program The Voyager program is a continuing American scientific program that employs two robotic probes, "Voyager 1" and "Voyager 2", to study the outer Solar System. They were launched in 1977 to take advantage of a favorable alignment of Jupiter, Saturn, Uranus, and Neptune, and are now exploring the outer boundary of the heliosphere in interstellar space. Although their original mission was to study only the planetary systems of Jupiter and Saturn, "Voyager 2" continued on to Uranus and Neptune, and both Voyagers are now tasked with exploring interstellar space. Their mission has been extended three times, and both probes continue to collect and relay useful scientific data. Neither Uranus nor Neptune has been visited by any probe other than "Voyager 2".

1999 TR11 1999 TR , also written as 1999 TR11, is a plutino (a trans-Neptunian object in 2:3 mean-motion resonance with Neptune). It was discovered on October 9, 1999, by Scott Sheppard observing from Mauna Kea with the 2.2 University of Hawaii reflector. It has a perihelion at 29.775 AU and an aphelion at 49.647 AU, so it moves in a relatively eccentric orbit (0.25) and it crosses the orbit of Neptune the same as Pluto.

Hulse–Taylor binary PSR B1913+16 (also known as PSR J1915+1606, PSR 1913+16, and the Hulse–Taylor binary after its discoverers) is a pulsar (a radiating neutron star) which together with another neutron star is in orbit around a common center of mass, thus forming a binary star system. PSR 1913+16 was the first binary pulsar to be discovered. It was discovered by Russell Alan Hulse and Joseph Hooton Taylor, Jr., of the University of Massachusetts Amherst in 1974. Their discovery of the system and analysis of it earned them the 1993 Nobel Prize in Physics "for the discovery of a new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation."
