Western University Astronomers Identify Cosmic Origin of Buckyballs Using JWST
Astronomers from Western University, led by Professor Jan Cami, have identified the cosmic birthplace of buckyballs, complex carbon molecules known as C60. Fifteen years after their initial discovery in space using the Spitzer Space Telescope, the team utilized the James Webb Space Telescope (JWST) to observe the planetary nebula Tc 1. Located 12,400 light-years away in the constellation Ara, Tc 1 surrounds a dying white dwarf star. The study, part of JWST Cycle 3, employed the Mid-Infrared Instrument (MIRI) to capture detailed images and rich spectral data. These findings reveal how these hollow, soccer-ball-shaped molecules form in extreme stellar environments. The research challenges traditional views on space chemistry and provides critical insights into carbon tracking and the potential origins of organic materials necessary for life. Supported by the Canadian Space Agency and NSERC, the project highlights the role of stellar remnants in synthesizing complex organic structures. The high-resolution images processed by the team offer unprecedented views of the nebula's gas shells and filaments, confirming theories about the abundance of fullerenes in the universe predicted by Nobel laureate Sir Harry Kroto.
