SN 2023xgo, a rare supernova with a helium-rich atmosphere, produced at least 0.03 solar masses of cool dust within a year of explosion—far more than typical supernovae. Infrared observations from JWST and other telescopes show the shockwave is still plowing into material the star shed before exploding, triggering rapid dust formation. This suggests certain types of supernovae are prolific dust factories.
