Queen's University Belfast students find Neptune's elusive Trojan asteroids
An international team led by researchers at Queen's University Belfast has made a discovery that has eluded astronomers for decades. Beginning in 1906, telescope observations revealed a population of asteroids leading and trailing Jupiter, which came to be known as the "Trojan" and "Greek" populations. Since then, astronomers have discovered similar "families" orbiting Saturn and Uranus, but not…
An international team from Queen's University Belfast has discovered Neptune's elusive Trojan asteroids, a discovery that had eluded astronomers for decades. The research, published in The Astrophysical Journal Letters, involved analyzing data from the Vera C. Rubin Observatory, a next-generation telescope situated in Chile. The team, led by Dr. Meg Schwamb, identified two confirmed asteroids and a candidate as permanent members of Neptune's trailing Trojans.
The discovery was made possible by the Rubin Observatory's advanced capabilities, which include high-resolution optics and the ability to rapidly survey the night sky. The team's findings, which were made possible by analyzing Rubin's early test observations, reveal that the trailing cloud of Neptune's Trojan asteroids has begun to move out of an obstructive region of the sky, allowing for more accurate detection.
This breakthrough will pave the way for future discoveries as the Rubin Observatory continues its large-scale survey of the southern sky, with the potential to uncover tens to hundreds of Neptune Trojans and thousands of other celestial bodies in the solar system.
