Alien Planets
Are Other Earths Lurking in Our Galaxy?
Antígona Segura Peralta
Professor of Astrobiology
National Autonomous University of Mexico
Professor Segura loved stars and was amazed with all living beings as a child, and as a result, she became an astrobiologist. She earned a B.S. in physics, an M.S. in astronomy and a Ph.D. in earth sciences before becoming a postdoctoral researcher in the Penn State Astrobiology Research Center and the NASA Jet Propulsion Laboratory in Pasadena, where she worked at the Virtual Planetary Laboratory. Now she is a researcher in Mexico City at the Instituto de Ciencias Nucleares at the Universidad Nacional Autónoma de México. She works on planetary habitability, remote detection of life, and early conditions of our solar system.
