Sir Frederick William Herschel, (15 November 1738 – 25 August 1822) was a German-born British astronomer, technical expert, and composer. Born in Hanover, Germany Wilhelm first followed his father into the Military Band of Hanover, but emigrated to Britain at age 19. Herschel became most famous for the discovery of Uranus in addition to two of its major moons, Titania and Oberon. He also discovered two moons of Saturn and infrared radiation. Herschel is also known for the twenty-four symphonies that he composed.
Knut Jørgen Røed Ødegaard
Knut Jørgen Røed Ødegaard (born 6 May 1966) is a Norwegian astronomer formerly employed as a media contact
at the University of Oslo's Institute of Theoretical Astrophysics. He was the leader of the Norwegian Astronomical Society (2005–2008), and is also manager of the Harestua Solar Observatory.
His enthusiasm for astronomy has made him a popular interview object
in Norwegian media for events such as the 2004 Transit of Venus and the 2005 landing of the Huygens probe on Titan, and for astronomy in general towards the general population.

Giorgio Abetti
Giorgio Abetti (5 October 1882 – 24 August 1982) was an Italian solar astronomer.
He was born in Padua, the son of noted astronomer Antonio Abetti. He was educated at the
Universities of Padua and of Rome.
He began his career at the Collegio Romano observatory in Rome as an assistant astronomer.
In 1921 he succeeded his father as the director of the Osservatorio Astrofisico di Arcetri, and
continued until 1957. Starting at the same time he was also a professor at the
University of Florence, and continued in this capacity until 1957.
Giorgio Abetti is noted for having led expeditions to observe solar eclipses to Siberia (1936) and Sudan (1952). He was also a visiting professor at the University of Cairo in 1948–49. He was the vice president of the International Astronomical Union in 1938, and
received the Medaglia d'argento from the Italian Geographic Society (1915), the Premio reale from the Accademia dei Lincei (1925), and the Janssen medal (1937)
The crater Abetti on the Moon and asteroid2646 Abetti are named to honor both him and his father.

Hannes Olof Gösta Alfvén
Hannes Olof Gösta Alfvén (born 30 May 1908 in Norrköping, Sweden; died 2 April 1995 in Djursholm, Sweden) was a Swedish electrical engineer, plasma physicist and winner of the 1970 Nobel
Prize in Physics for his work on magnetohydrodynamics
(MHD). He described the class of MHD waves now known as Alfvén waves. He was originally trained as an electrical power engineer and later moved to research and teaching in the fields of plasma physics and electrical engineering. Alfvén made many contributions to plasma physics, including theories describing the behavior of aurorae, the Van Allen radiation belts, the effect of magnetic storms on the Earth's
magnetic field, the terrestrial magnetosphere, and the dynamics of plasmas in the
Milky Way galaxy

Terence Dickinson
Terence Dickinson, CM (born 1943) is a leading amateur astronomer and science writer who lives near the rural town of Yarker, Ontario, Canada. He is the editor of SkyNews magazine and an astronomy commentator for Discovery Channel Canada. He has written fourteen books, which are widely regarded as some of the best resources available for beginners in astronomy. Dickinson teaches part-time at St. Lawrence College and the asteroid 5272 Dickinson is named after him. He has also made appearances at places such as the Ontario Science Centre.
Carl Edward Sagan
Carl Edward Sagan ( /ˈseɪɡɪn/; November 9, 1934 – December 20,
1996) was an American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator in astronomy and natural sciences. He published more than 600 scientific papers and
articles and was author, co-author or editor of more than 20 books. He advocated scientifically skeptical inquiry and the scientific method,
pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI).
Sagan is known for his popular science books and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote. The book Cosmos was published to accompany the series. Sagan wrote the novel Contact, the basis for a 1997 film
of the same name.
