Story summary

Scientists studied supernova SN2021yfj, uncovering silicon and sulfur layers, which challenge existing stellar evolution models.
The star shed its outer layers prior to the explosion, indicating possible pair-instability processes.
Ongoing research will seek similar supernovae to enhance understanding of these events.
The findings were published in Nature on August 20, 2025.
