Molecular hydrogen in the extremely metal- and dust-poor galaxy Leo P
Nature, Published online: 11 June 2025; doi:10.1038/s41586-025-09115-7Observations from the JWST MIRI-MRS instrument reveal the detection of rotational emission from molecular hydrogen near the only O-type star in the 3% solar metallicity galaxy Leo P, providing confirmation that significant quantities of molecular gas can form in such metal- and dust-poor environments.
