Optically Dark Gamma‑Ray Burst Shows Exceptionally Wide Jet
An international team observed GRB 250416C, a gamma‑ray burst that was optically dark yet exhibited an unusually wide jet structure. Multi‑wavelength data, posted as a pre‑print on 23 April, could refine theoretical models of burst energetics and jet formation. The story was published on Phys.org on 4 May 2026.
