Meet the AAS Keynote Speaker: Prof. Mario Jurić
In this article, we delve into the fascinating world of Professor Mario Jurić, a renowned astronomer and leader in one of the most ambitious surveys in the field. With a background in physics and a passion for data-intensive projects, Jurić is revolutionizing our understanding of the Solar System and the universe.
The Digital Revolution and Large Surveys
Jurić's journey began with a realization during his graduate studies. He discovered that his research involved estimating distances to an astonishing 48 million stars, a feat that was almost 700 times more than any previous paper on a similar topic. This sparked his interest in large surveys, which were made possible by the digital revolution in the early 2000s. The advent of software as a crucial component in astronomy, alongside telescopes and cameras, marked a turning point in his career.
The Sloan Digital Sky Survey (SDSS) played a pivotal role in this transformation. It was a groundbreaking project that counted gigabytes of data instead of photographic plates. Jurić's involvement with SDSS led him to work on exoplanet dynamics for his PhD at Princeton, where he became immersed in the world of large surveys.
The Vera C. Rubin Observatory and LSST
Today, Jurić is a key figure in the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). This ambitious project aims to map the entire Southern night sky every three nights over the next decade, creating one of the most versatile and accessible datasets in astronomy. Jurić's expertise lies in studying asteroids and comets within our Solar System, and he believes that LSST has the potential to revolutionize our understanding of these celestial bodies.
With LSST, Jurić expects to double the number of known asteroids within the next year and a half, and even triple them by the end of the survey. The project also aims to discover almost a factor of 7 more trans-Neptunian objects and a factor of 2 more potentially hazardous asteroids. These discoveries will provide valuable insights into the formation and composition of our Solar System, as well as the birth locations and migration patterns of our planets.
A Data-Driven Approach
Jurić's work is deeply intertwined with data-driven astronomy. He emphasizes the importance of open-source analysis code, making it freely available on Rubin's GitHub. This approach democratizes access to scientific data, allowing astronomers worldwide to contribute to the project and explore its vast dataset.
However, Jurić also advises students to be cautious when joining large projects. He believes that taking risks with smaller, novel projects can be more rewarding, as the field of astronomy is rapidly evolving. He encourages students to pursue ideas that can be evaluated within a few years, as the universe is constantly revealing new secrets.
Personal Insights and Future Endeavors
Despite his busy schedule working on a once-in-a-quarter-century project, Jurić finds time to spend with his family and engage in various hobbies, including astronomy outreach, rock climbing, and playing board games. His passion for the field and his dedication to sharing knowledge make him an invaluable contributor to the astronomical community.
As a keynote speaker at the AAS, Jurić will present some of the first Solar System discoveries and results with the Rubin Observatory. His talk, scheduled for June 15, 2026, promises exciting new announcements. Jurić's enthusiasm for unraveling the universe's mysteries is infectious, and his work continues to shape our understanding of the cosmos.
