Rob Ivison is a British astronomer and ESO director who has made major contributions to submillimeter astronomy and the study of galaxy formation.

Harold Irving Ewen was an American physicist recognized for his contribution to early radio astronomy. While a graduate student at Harvard University in 1951, he partnered with his advisor, Edward Mills Purcell, to detect the 21-centimeter hydrogen line. Using a custom-built horn antenna, they obser...

Karl Jansky was an American engineer and astronomer whose work fundamentally changed our understanding of the universe. In 1932, he detected naturally occurring radio waves emanating from space, originating beyond our solar system. This discovery established radio astronomy as a distinct field. Jans...

Jocelyn Bell Burnell is a pioneering British astrophysicist renowned for her discovery of the first radio pulsars in 1967 while a graduate student at Cambridge University. Her meticulous observations revolutionized our understanding of these rapidly rotating neutron stars and dramatically advanced t...

Jacqueline van Gorkom is a Dutch radio astronomer and professor at Columbia University, known for her extensive research using the Very Large Array to study neutral hydrogen (HI) in and around galaxies. Her work has provided key insights into gas accretion, gas stripping in clusters, and the role of...

Grote Reber was an American pioneer of radio astronomy who built the world's first purpose-built parabolic radio telescope in 1937. Constructed in his backyard in Wheaton, Illinois, the 31.4-foot dish allowed him to systematically survey the sky for cosmic radio frequencies. Reber spent years mappin...

Iosif Shklovsky (1916–1985) was a Soviet astronomer and astrophysicist who made significant contributions to theoretical astrophysics and radio astronomy. He is best known for demonstrating that the radio emission from the Crab Nebula is synchrotron radiation generated by electrons moving at near-li...

Yervant Terzian was an Armenian-American astronomer who served as a professor and department chair at Cornell University. His academic research focused extensively on radio astronomy and planetary nebulae, contributing to the understanding of stellar evolution and the interstellar medium. He also me...

George Smoot is an American astrophysicist renowned for his pivotal role in detecting subtle temperature fluctuations within the cosmic microwave background radiation. His work, utilizing precise radio astronomy measurements and drawing on principles of quantum mechanics, provided critical evidence...

Nikolai Kardashev was a Soviet and Russian astrophysicist who made foundational contributions to the fields of experimental and theoretical radio astronomy. He is best known for proposing the Kardashev scale in 1964, a theoretical method of classifying extraterrestrial civilizations based on the amo...

Frank Drake was a pioneering American astronomer instrumental in the quest to discover life beyond Earth. He established the SETI program, focused on searching for intelligent extraterrestrial signals. Drake’s work is notable for developing the Drake Equation, a mathematical framework used to estima...
