In the vast expanse of the cosmos, few individuals have dedicated their lives to the pursuit of knowledge as relentlessly as Mario Jurić. As a professor and Senior Data Science Fellow at the University of Washington, Jurić is at the forefront of one of the most ambitious surveys in astronomy: the Legacy Survey of Space and Time (LSST) at the Vera C. Rubin Observatory. This project, set in the pristine darkness of the Chilean desert, aims to map the entire Southern night sky every three nights over the next decade, offering a treasure trove of data for the astronomical community.
Jurić's journey into the world of survey astronomy began with a realization while writing one of his first papers. He discovered that he had estimated distances to 48 million stars, a feat that was almost 700 times more than any previous paper on a similar topic. This realization came at a pivotal time in the history of observational astronomy, when the digital revolution was transforming the field. The turn of the century saw software becoming as important as telescopes and cameras, propelling Jurić's career and the field of survey astronomy forward.
From his early work on exoplanet dynamics at Princeton to his current position at the University of Washington, Jurić has been a constant thread in the evolution of large, data-intensive surveys. He credits the digital revolution with propelling his career and the field forward, and he is particularly excited about the potential of the LSST to revolutionize our understanding of the Solar System. With the LSST, Jurić expects to double the number of known asteroids in the next year and a half, triple them by the end of the survey, and find almost a factor of 7 more trans-Neptunian objects.
However, Jurić's passion for survey astronomy is not solely driven by the potential for groundbreaking discoveries. He is also fascinated by the democratization of access to scientific data that the LSST offers. All of its analysis code is open-source and freely available on Rubin's Github, and access is not limited to any specific country or institution. This equal access is a key feature of the LSST, and Jurić encourages everyone to get involved in digging through its data goldmine.
Despite his excitement about the LSST, Jurić cautions students just starting out in research to be careful about joining large projects where the payoff is far in the future. He advises them to pursue novel or out-of-the-box projects where they can see immediate results and know if their big ideas have succeeded or not in the next few years. This advice is particularly relevant in the rapidly evolving field of astronomy, where knowledge of the universe is being rewritten faster than you might perceive in a day-to-day routine.
In the end, Jurić's work on the LSST is a testament to the power of human curiosity and the relentless pursuit of knowledge. As he prepares to give a Plenary Talk at the AAS248 meeting, he emphasizes the importance of not letting the universe keep secrets from us. With the LSST, he believes that we are on the cusp of making groundbreaking discoveries that will change our understanding of the cosmos. And as we look to the future, it is clear that Jurić's work will continue to shape the field of astronomy for years to come.
