Dust might not sound like the most interesting of topics, but to a certain set of astronomers, it’s thrilling. Researchers recently used the James Webb Space Telescope to identify grains of dust from the early universe, which could have been produced by the earliest supernovas.
Using the spectrograph, the researchers found evidence of carbon-rich grains in dust clouds. That appears to be similar to findings of compounds called polycyclic aromatic hydrocarbons , however, it wouldn’t have been possible for these complex compounds to have formed so early in the universe.
