José V. Siles is a radio frequency engineer at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. His research area is known as plantary science, i.e. the study of the celestial bodies that orbit stars, with a particular focus on our own solar system. José and his colleagues are trying to understand the life cycle of stars, how they form, how they die... because stars may hold the answer to the question: where do we come from?
