| IRS990/Desc | 0 | CONTINUING A 130+-YEAR-LONG LEGACY OF ASTRONOMICAL DISCOVERY, LOWELL OBSERVATORY ASTRONOMERS, PLANETARY SCIENTISTS, AND OTHER RESEARCHERS CONDUCTED FOREFRONT RESEARCH IN MANY AREAS OF ASTRONOMY FROM THE SUN AND OUR SOLAR SYSTEM TO EXOPLANETS, STARS, GALAXIES, AND COSMOLOGY. IN 2024, LOWELL SCIENTISTS PUBLISHED OVER 120 PEER-REVIEWED PAPERS IN LEADING SCIENTIFIC JOURNALS, ALONG WITH ANOTHER 69 PAPERS IN OTHER VENUES. LOWELL SCIENTISTS ALSO GAVE NUMEROUS PRESENTATIONS AT SCIENTIFIC CONFERENCES AND PUBLIC OUTREACH EVENTS AND PARTICIPATED IN MAJOR SCIENTIFIC MISSIONS USING WORLD-LEADING TELESCOPES ACROSS THE GLOBE AND IN SPACE. LOWELL SCIENTIFIC STAFF CONTINUE TO BE VERY SUCCESSFUL AT OBTAINING GRANTS IN SUPPORT OF THEIR RESEARCH FROM NASA, THE NATIONAL SCIENCE FOUNDATION, AND OTHER AGENCIES.THE 4.3-METER LOWELL DISCOVERY TELESCOPE (LDT) DELIVERED APPROXIMATELY 257 SCIENCE NIGHTS USED BY ASTRONOMERS ON THE STAFF AT LOWELL, AND OUR PARTNER INSTITUTIONS: BOSTON UNIVERSITY, NORTHERN ARIZONA UNIVERSITY, THE UNIVERSITY OF MARYLAND, THE UNIVERSITY OF TOLEDO, AND YALE UNIVERSITY. IN TOTAL, THE LDT FEATURED PROMINENTLY IN MORE THAN 45 SCIENTIFIC OR TECHNICAL PUBLICATIONS. THE LDT'S GROWING SUITE OF STATE-OF-THE-ART INSTRUMENTS, SUCH AS THE HIGH-PRECISION SPECTROGRAPH EXPRES, ENABLE CUTTING EDGE RESEARCH ACROSS MULTIPLE FIELDS, INCLUDING THE SEARCH FOR EXOPLANETS. LOWELL OBSERVATORY ALSO CONTINUED TO OPERATE OTHER SMALLER RESEARCH TELESCOPES AT ITS ANDERSON MESA AND MARS HILL SITES; AT THE MESA THEY ARE OPERATING A MODERN 1-METER TELESCOPE EQUIPPED WITH BOTH IMAGING AND SPECTROSCOPIC CAPABILITIES. ACCESS TO LOCAL TELESCOPES EQUIPPED WITH WORLD-CLASS INSTRUMENTS HAS ENABLED SCIENCE THAT COULD NOT BE DONE ELSEWHERE. IN 2024, LOWELL OBSERVATORY LAUNCHED ITS SCIENCE VISION, A LONG-TERM PLAN TO ADVANCE OBSERVATIONAL AND TECHNICAL EXCELLENCE. THIS STRATEGIC INITIATIVE OUTLINES MAJOR NEW GOALS, INCLUDING SIGNIFICANT UPGRADES TO THE LDT, THE DEVELOPMENT OF NEXT-GENERATION INSTRUMENTATION, NEW PATHWAYS FOR PUBLIC ENGAGEMENT WITH SCIENTIFIC DISCOVERY, AND EXPANDED OPPORTUNITIES FOR THE NEXT GENERATION OF ASTRONOMERS AND ENGINEERS. EARLY IMPLEMENTATION EFFORTS BEGAN IN 2024, INCLUDING PLANNING FOR AN UPGRADED ADAPTIVE OPTICS SYSTEM AND FEASIBILITY STUDIES FOR FUTURE LARGE-APERTURE FACILITIES.LOWELL OBSERVATORY REMAINS COMMITTED TO PIONEERING RESEARCH, TECHNOLOGICAL INNOVATION, AND SHARING DISCOVERY WITH THE BROADER COMMUNITY. |

THE BIG CHANGE IN 2024 WAS THAT AFTER FOUR YEARS OF CONSTRUCTION AND RAISING $53.6 MILLION DOLLARS FOR THE NEW FACILITY, LOWELL OBSERVATORY CELEBRATED THE GRAND OPENING OF THE MARLEY FOUNDATION ASTRONOMY DISCOVERY CENTER (ADC) IN NOVEMBER 2024. THE ADC IS A PLACE THAT SPARKS CURIOSITY AND DISCOVERY FOR VISITORS FROM AROUND THE GLOBE. THE THREE-STORY, 40,200-SQUARE-FOOT ADC FEATURES A STATE-OF-THE-ART THEATER, EXHIBIT GALLERIES, AND A ROOFTOP AMPHITHEATER FOR EXPLORING FLAGSTAFF'S FAMOUSLY DARK SKIES.
