Hoyle, Sir Fred (1915-2001), a British astronomer, noted for research on the development of stars.
Argelander, Friedrich Wilhelm August (1799-1875) was a Finnish-German astronomer and professor of astronomy who compiled the Banner Durchmusterung, a catalog which recorded the positions and magnitudes of 324,198 stars of the northern celestial hemisphere.
Bessel, Friedrich Wilhelm (1784-1846), a German astronomer, was the first to measure stellar parallax, an apparent change in a star's position as a result of the earth orbiting the sun.
Schiaparelli, Giovanni Virginia (1835-1910), was an Italian astronomer. He is best known for his studies of Mars, begun in 1877, in which he described in detail the Martian canals.
Bradley, James (1693-1762), an English astronomer, discovered the aberration of starlight that provided the first direct proof that the earth revolves around the sun, and the nutation, or nodding motion, of the earth's axis.
Bell Burnell, Jocelyn (1943-), a Northern Irish astronomer, discovered the first four pulsars, neutron stars that emit pulses of radiation with a high degree of regularity.
Adams, John Couch (1819-1892), was a British astronomer and one of the discoverers of the planet Neptune.

Lockyer, Sir Joseph Norman (1836-1920), an English astronomer. He was one of the first to study the sun and stars with a spectroscope.
Von Kármán, Theodore (1881-1963) was a Hungarian-born American physicist and engineer who made great contributions to the field of aerodynamics and rocket technology.
Sitter, Willem de (18721934), a Dutch astronomer. He was a pioneer in applying Albert Einstein's theory of relativity to astronomy and developed a model of an expanding, curved universe.
Campbell, William Wallace (1862-1938), an American astronomer, made important measurements of the motion of stars.
