Faint X-ray shock breakout reveals a new path for massive-star deaths (SN 2026gzf)

Astronomers tracked SN 2026gzf from its faint X-ray shock breakout to its early light across multiple wavelengths, revealing a broad-lined Type Ic explosion from a Wolf‑Rayet star about 500 million light-years away that did not produce a gamma-ray burst. The rapid, multi-instrument follow-up mapped the explosion and its interaction with surrounding material, suggesting diverse pathways to such energetic deaths beyond GRB jets and shedding light on the star’s final years.
