Kelly LepoA neat interdisciplinary science story from Olivier Berne and the PDRs4All project.
They saw this forrest of emission lines in their observations of the Orion Bar, a star forming region. After talking with some chemists, they found it was from the Methyl-Cation (CH3+).
Chemists had been studying it for years, but didn't have a great spectrum. The JWST data is better than anything that could be measured on Earth. With the new data, they were able to make a much better model.
