Michael E. Brown (born June 5, 1965) is an American astronomer and planetary scientist known for his significant contributions to the study of the outer Solar System, particularly his discovery of Eris, which led to the reclassification of Pluto from a planet to a dwarf planet. Here is a detailed biography of Michael E. Brown:
Early Life and Education (1965–1987):
- Birth and Family: Michael E. Brown was born on June 5, 1965, in Huntsville, Alabama, USA.
- Educational Background: Brown developed an early interest in astronomy. He earned his Bachelor of Science degree in Physics from Princeton University in 1987.
- Doctoral Studies: Brown continued his education at the University of California, Berkeley, where he pursued a Ph.D. in astronomy. He completed his doctoral studies in 1990.
Academic Career and Research (1990–Present):
- Postdoctoral Research: After completing his Ph.D., Brown conducted postdoctoral research at the University of California, Berkeley, and at the California Institute of Technology (Caltech).
- Faculty Appointment at Caltech: Brown joined the faculty at Caltech in 1996, where he is currently a Professor of Planetary Astronomy.
- Research Focus: Michael E. Brown has focused his research on the outer Solar System, particularly the Kuiper Belt—a region of the Solar System beyond Neptune that contains numerous small, icy bodies.
- Discovery of Eris: In 2005, Brown and his team discovered Eris, a trans-Neptunian object that was initially thought to be larger than Pluto. This discovery prompted the International Astronomical Union (IAU) to reconsider the definition of a planet and ultimately led to the reclassification of Pluto as a dwarf planet.
- Other Discoveries: Brown and his team have been involved in the discovery of numerous other trans-Neptunian objects, including Haumea, Makemake, and Sedna.
- Sedna Discovery Controversy: Brown’s team was involved in the discovery of Sedna, an object with an unusually elongated orbit. The discovery led to debates about the existence of a hypothetical distant giant planet in the outer Solar System.
Publications and Outreach:
- Scientific Publications: Brown has authored or co-authored numerous scientific papers and publications in the field of astronomy, planetary science, and astrophysics.
- Popular Science Writing: In addition to his academic work, Brown has written popular science articles and books, making complex astronomical concepts accessible to a broader audience.
Honors and Recognition:
- Awards: Brown has received various awards for his contributions to astronomy, including the Urey Prize from the American Astronomical Society.
- Eponymous Asteroid: The asteroid 11714 Mikebrown, discovered in 1998, is named in his honor.
- Popular Media Appearances: Brown’s work has gained significant attention in the media, and he has appeared in documentaries, interviews, and popular science programs.
Personal Life:
- Family: Information about Michael E. Brown’s personal life, including his family, is not extensively publicized.
Michael E. Brown’s research has had a profound impact on our understanding of the outer Solar System. His contributions to the discovery of Eris and other trans-Neptunian objects have reshaped the way scientists classify and understand celestial bodies in our cosmic neighborhood.
