Name	Country	Born	Died	Notable for
Marc Aaronson	United States	1950	1987	His work concentrated on three fields: the determination of the Hubble constant (H₀) using the Tully–Fisher relation, the study of carbon rich stars, and the velocity distribution of those stars in dwarf spheroidal galaxies. Aaronson was one of the first astronomers to attempt to image dark matter using infrared imaging. He imaged infrared halos of unknown matter around galaxies that could be dark matter.
Hiroshi Abe	Japan	1958
George Ogden Abell	United States	1927	1983
Antonio Abetti	Italy	1847	1928	Abetti mainly worked in positional astronomy and made many observations of minor planets, comets, and star occultations. He computed the orbit of 170 Maria, a Main belt asteroid.
Giorgio Abetti	Italy	1882	1982
Charles Greeley Abbot	United States	1872	1973
Charles Hitchcock Adams	United States	1868	1951
John Couch Adams	United Kingdom	1819	1892	His most famous achievement was predicting the existence and position of Neptune, using only mathematics. The calculations were made to explain discrepancies with Uranus's orbit and the laws of Kepler and Newton.
Walter Sydney Adams	United States	1876	1956
Saul Adelman	United States	1944
Petrus Alphonsi	Spain	1062	1110
Agrippa	Greece	fl. c. 92 CE		Agrippa observed the occultation of a part of the Pleiades by the southernmost part of the Moon.
Paul Oswald Ahnert	Germany	1897	1989
Eva Ahnert-Rohlfs	Germany	1912	1954
George Biddell Airy	United Kingdom	1801	1892
Robert Aitken	United States	1864	1951
Makio Akiyama	Japan	1950
Abd Al-Rahman Al Sufi	Persia	903	986
Albategnius (see Al-Batani)	Syria	c. 858	929	Al-Battānī's observations of the Sun led him to understand the nature of annular solar eclipses. He accurately calculated the Earth's obliquity (the angle between the planes of the equator and the ecliptic)
Vladimir Aleksandrovich Albitzky	Russia	1891	1952
Albumasar	Persia	787	886
George Alcock	United Kingdom	1913	2000	Discovered comets C/1959 Q1, C/1959 Q2, C/1963 F1 and C/1965 S2.
Harold Alden	United States	1890	1964
Hannes Alfvén	Sweden	1908	1995
Lawrence H. Aller	United States	1913	2003
Viktor Amazaspovich Ambartsumian	Armenia	1912	1996	One of the 20th century's top astronomers, he is widely regarded as the founder of theoretical astrophysics in the Soviet Union.
John August Anderson	United States	1876	1959
Wilhelm Anderson	Estonia	1880	1940	Best known for his work on the mass limit for a white dwarf
Marie Henri Andoyer	France	1862	1929
Andronicus of Cyrrhus	Greece	fl. c. 100 BC
Anders Jonas Ångström	Sweden	1814	1874
Eugène Michel Antoniadi	Greece/France	1870	1944	He made the first map of Mercury (although his maps were flawed due to incorrectly assuming that Mercury had synchronous rotation with the Sun)
Masakatsu Aoki	Japan	1957
Petrus Apianus	Germany	1495	1557
François Arago	France	1786	1853
Masaru Arai	Japan	1952
Hiroshi Araki	Japan
Sylvain Arend	Belgium	1902	1992
Friedrich Wilhelm Argelander	Germany	1799	1875
Aristarchus of Samos	Greece	c. 310 BC	c. 230 BC	He presented the first known heliocentric model that placed the Sun at the center of the known universe, with the Earth revolving around the Sun once a year and rotating about its axis once a day.
