Astrophysicists

Public Welfare Medal-winning astrophysicist and academic Neil deGrasse Tyson hosted shows such as NOVA ScienceNow, Cosmos: A Spacetime Odyssey, and Star Talk. He is the director of Hayden Planetarium and contributed to the dismissal of Pluto’s status as the ninth planet. He has also written a monthly column as "Merlin.”

When the American government, baffled by unexplained sightings of flying objects, assigned J. Allen Hynek the task of solving the mystery, Hynek was sceptical. However, he later became the first person to scientifically analyze such sightings. He also established the "Close Encounter" classification system to study UFOs.

Jocelyn Bell Burnell is an astrophysicist from Northern Ireland. As a postgraduate student, she discovered the first radio pulsars. She graduated from the University of Glasgow and pursued an academic career. In 2018, she received the Special Breakthrough Prize in Fundamental Physics for her discovery of radio pulsars. She donated the three million dollars she received as prize money.  

Born to math professor Harold S. Shapiro, Max Tegmark grew up to co-establish the Future of Life Institute, with funding from Elon Musk. The MIT professor is a specialist in cosmology, physics, and machine learning and had also penned a book on artificial intelligence, titled Life 3.0.

Karl Schwarzschild was a German astronomer and physicist. He is remembered for his contributions to the general theory of relativity; Schwarzschild came up with the first exact solution to the Albert Einstein field equations. He also contributed immensely to the theory of black holes.

Born to a math professor father and a Sanskrit scholar mother, Astrophysicist and IUCAA professor Jayant Narlikar grew up to collaborate with Sir Fred Hoyle, leading to the conformal gravity theory, also known as the Hoyle-Narlikar theory. He has won the Padma Bhushan and Padma Vibhushan and penned sci-fi novels, too.

American-Canadian theoretical physicist Lawrence M. Krauss has taught at institutes such as ASU and Yale and also penned several bestselling books. Known for his research on dark energy and zero-energy states, he was later accused of sexual misconduct and thus lost the directorship of the ASU’s Origins Project.

Indian astrophysicist Meghnad Saha is best remembered for developing the thermal ionization equation. A grocer’s son, he relied on merit alone to excel in academics and eventually became a professor at the universities of Allahabad and Calcutta. He was also a Lok Sabha MP and a Fellow of the Royal Society.

Astronomer Amy Mainzer has been associated with NASA's NEOWISE mission and specializes in asteroid detection. The Stanford and Caltech alumna now teaches at the Lunar and Planetary Laboratory of the University of Arizona and has also appeared on the History Channel series The Universe and in several documentaries.

The first British astronaut to perform a space-walk, Michael Foale was also the only NASA astronaut to be on missions aboard both the Mir and the International Space Station. Born to a Royal Air Force pilot father, he was well-traveled. He was the only survivor of a car accident in Yugoslavia.

Dennis W. Sciama was a British physicist credited to have played a major role in the development of British physics following World War II. He is considered a co-father of modern cosmology and supervised the doctoral works of many famous cosmologists, including Martin Rees and Stephen Hawking.  He was elected a Fellow of the Royal Society (FRS) in 1983. 

Nobel Prize-winning astrophysicist Saul Perlmutter has been associated with the Lawrence Berkeley National Laboratory and teaches at the University of California, Berkeley. Born to a chemical engineering professor, Perlmutter grew up to co-discover the accelerating expansion of the Universe and later introduced innovative Berkeley courses such as Physics & Music.

Known as “The Poet of the Stars,” Canadian astrophysicist Hubert Reeves has been a NASA advisor. His research covers neutrinos and thermonuclear reactions in stars. Having penned numerous science and astronomy books such as Soleil, he is known as a popularizer of science and has an asteroid named after him.

Nobel Prize-winning physicist Robert Hofstadter is remembered for his path-breaking research on the structures of the particles of the atomic nuclei, such as protons and neutrons. The Princeton alumnus initially worked with the National Bureau of Standards, where he developed the proximity fuse, and then taught at Princeton and Stanford.

Adam Guy Riess is an American astrophysicist, known for his work on Type Ia supernovae. Teaming up with Saul Perlmutter and Brian Schmidt, he started working on the supernovae, using it as cosmological probe, eventually discovering that the expansion rate of the universe is accelerating. He received the 2011 Nobel Prize in Physics for his work.

Lyman Spitzer was an American theoretical physicist, mountaineer, and astronomer. He was known for his research into star formation and plasma physics. He is credited with the invention of the stellarator plasma device and he was the one who first conceived the idea of telescopes operating in outer space. He was a founding member of the World Cultural Council. 

Margaret Burbidge was a British-American observational astronomer and astrophysicist. She was the first author of the influential B2FH paper and one of the founders of stellar nucleosynthesis. She held several leadership and administrative posts and was well known for her work opposing discrimination against women in astronomy. In 1988, she was awarded the Albert Einstein World Award of Science. 

Renowned astrophysicist Alexei Filippenko, who teaches at the University of California, Berkeley, is primarily focused on supernovae and galaxies. Apart from writing 900 research papers, he has also penned a bestselling book and appeared on programs such as The Universe. He loves tennis and often travels to view solar eclipses.
