Whether it is planetary science, astronomy, meteorology, astrophysics, or life sciences, any study dealing with Earth’s atmosphere and the bounds beyond our planet is classified as space science. This broad area of study encompasses many disciplines and borrows theories and strategies of study from all scientific branches. Outstanding space scientists contribute to our understanding of the world, the solar system, and the true final frontier of space.
Perhaps most interesting about space science are those who participate in its progress. As a modern field that boomed in the second half of the 20th century and continues to grow today, space scientists come from all walks of life. Some of the work they do is theoretical, relying on mathematical models and space-age images of suns, moons, planets, and more. Others use vehicles, such as the Mars Rover, to conduct physical research wherein their primary responsibility is building and enhancing technology to conduct long-distance research. Ultimately, space scientists work to understand how the universe works.
Check out the stellar careers of these ten outstanding space scientists.
Famous Astrophysicist: Stephen Hawking
In discussing outstanding space scientists, Stephen Hawking cannot be forgotten. His research as a cosmologist fundamentally built contemporary understandings of the universe and its governing laws. Moreover, his immense stamina to publish despite amyotrophic lateral sclerosis (ALS) made his contribution to society memorable and motivational.
Hawking earned his bachelor’s degree at University College, Oxford (part of the University of Oxford). There, he studied physics and took a deep interest in the theoretical elements of the field. He went on to study at Cambridge, earning his Ph.D. in applied mathematics and theoretical physics with a specialization in cosmology and general relativity. In addition to his school-earned degrees, Hawking received more than a dozen honorary degrees.
While Hawking’s published works about String Theory and the Big Bang Theory are for what he is best remembered, his career as a professor was extensive. He began as a Professorial Fellow with Gonville and Caius College. After, he held the title of Lucasian Professor at his doctoral alma mater. He also served as the Director of Research at Cambridge’s Centre for Theoretical Cosmology.
Ultimately, Hawking’s contributions to space science as a cosmologist emphasized the role black holes play in the universe. He and collaborator Roger Penrose developed theorems on gravitational singularity, general relativity, and black hole radiation. Moreover, he is credited as the first scientist to identify a cosmological theory uniting quantum mechanics and the theory of relativity.
For his work, Hawking received numerous awards. Among these was the U.S. Presidential Medal of Freedom. Additionally, he was a member of several societies. He was a Fellow of the Royal Society, a member of the US National Academy of Sciences, and a lifetime member of the Pontifical Academy of Sciences.

Famous Space Scientist: Carl Sagan
Like the other big names in this list, Carl Sagan is an outstanding space scientist without whom much of today’s research would not be possible. His contribution to the field extends beyond hard data research or theoretical contributions; his work brought to the public clear, concrete understandings of the universe.
An alumnus of the University of Chicago, Sagan earned three degrees there. His bachelor’s and master’s degrees were both in physics. However, for his Ph.D., he switched to an emphasis in astrophysics and astronomy. Sagan completed his post-doctoral research at the University of California, Berkeley.
While Sagan’s initial research focused on planetary science, he quickly became interested in extraterrestrial life and intelligence. Although the field was controversial during Sagan’s life, much of the work he completed toward the end of his life was in astrobiology. Most of his fieldwork was with Cornell University’s Laboratory for Planetary Studies. Sagan later founded the Planetary Society and was also its first president.
Although he is famous in the scientific community, he is also generally popular. Sagan published science fiction novels and other books as well as hosted a television series called “Cosmos.” In that series, he taught the world about space science, particularly astronomy and astrophysics. However, the unique element in this production was taking abstract concepts and delivering them in understandable soundbites that could be used in a variety of settings from classrooms to households.
Ultimately, Sagan earned many awards for his contributions to the scientific community. Notably, from NASA, he received medals for Exceptional Scientific Achievement and Distinguished Public Service and the Apollo Achievement Award. He also received the John F. Kennedy Astronautics Award and the Explorers Club 75th Anniversary Award among others.
