About
Mike DiVittorio is a dedicated astronomer whose work centers on astrometry—the precise measurement of celestial positions—and the development of robotic telescopes for large-scale sky surveys. His most notable contribution is his involvement in the creation of the U.S. Naval Observatory Robotic Astrometric Telescope 1st Catalog (URAT1), a foundational dataset that provides highly accurate positions and proper motions for millions of stars. This catalog, published in 2015, has been cited twice, reflecting its specialized but critical role in supporting subsequent astrometric research, including the calibration of space-based missions like Gaia. DiVittorio’s expertise in telescope automation and data reduction has been instrumental in advancing the field of ground-based astrometry, enabling more precise mapping of the Milky Way. His work exemplifies the meticulous, behind-the-scenes effort required to build the reference frames that underpin modern astrophysics, from exoplanet detection to studies of stellar dynamics. For students and researchers, DiVittorio’s contributions highlight the enduring value of careful observational astronomy and the importance of robust cataloging in an era of big data.
