Geronimo L. Villanueva (born April 9, 1978) is a planetary astronomer at NASA Goddard Space Flight Center[1]. His work on high-resolution molecular spectroscopy of planetary and cometary atmospheres led the International Astronomical Union to name minor planet 9724 after Villanueva[2], while the American Astronomical Society awarded him the Urey Prize (young planetary scientist of the year) in 2015[3]. His research ranges from instrument design and development of the highest resolution spectrometer for the airborne SOFIA (Stratospheric Observatory for Infrared Astronomy)[4], to quantum mechanical molecular modeling, to observational astronomy and data analysis. Some of his contributions include the identification of an ancient ocean on Mars[5][6][7][8], sensitive searches of primordial water in comets,[9] and the search and possible discovery of organics on Mars[10][11][12][13][14].
Early life
Villanueva is a Mendoza, Argentina native, having lived in several provinces of Argentina (Mendoza, Córdoba, Santiago del Estero, Buenos Aires) and in Asunción, Paraguay. His heritage is Italian, Spanish and French. He earned his undergrad studies and Master degree at Universidad de Mendoza. He conducted his Ph.D. research in Germany at the Max Planck Institute for Solar System Research from 2001 to 2004, graduating in November 2004 at the Freiburg University. He was awarded a National Research Council (United States) fellowship in 2005 to conduct planetary research at NASA Goddard Space Flight Center.
Career
Villanueva is known in the scientific community for his planetary spectroscopy work and spectral databases / models applicable to planets, comets and small icy bodies. He obtained the first mapping of water D/H on Mars, revealing an ancient ocean on Mars and unexpected strong isototopic anomalies across the planet;[5][6] obtained the first astronomical measurement of water D/H of a periodic comet;[9] acquired a deep search for organics in the Martian atmosphere,[10] and discovered multiple isotopic carbon dioxide bands on Mars at infrared wavelengths. He develops non-LTE radiative transfer models and quantum molecular models at GSFC resulting in billions of spectral lines suitable for cometary, planetary and astrophysical sciences, including exoplanets.[15] During his Ph.D thesis, he was the lead designer and developer of the high resolution spectrometer onboard SOFIA,[4] and developed a full non-linear dynamical General Circulation Model (GCM) for Mars.[4]
Honors, awards and accolades
In 2015 the American Astronomical Society awarded Villanueva with the Harold C. Urey Prize (Young planetary scientist of the year),[3] while in 2014 the International Astronomical Union named minor planet 1981EW17 “(9724) Villanueva”, in honor to Dr. Villanueva’s research contributions in the area of high-resolution molecular spectroscopy of planetary and cometary atmospheres.[2] Some recent highlights include: article of the day (Astrophysics Data System, Oct/12/2011), lead author and co-author of three Astronomy Picture of the Day (Dec/22/2014, Jan/19/2009, Feb/21/2009), and lead author of one of the most popular planetary articles of 2013.[16]
Social activism
He is an advocate for Space Exploration and Astronomy to under-privileged communities, frequently participating public outreach activities, and has served as a science communicator for the U.S. State Department and Shakira's Barefoot Foundation to promote science in developing regions.
