Catching distant gamma-ray explosions with precisely aligned X-ray optics

Gamma-ray bursts (GRBs) rank among the most powerful explosions in the universe, releasing immense energy in intense flashes of gamma rays. The most distant GRBs originate from the era when the first stars and galaxies formed. Detecting them allows astronomers to probe the early universe and understand how the first heavy elements formed and how the earliest stellar populations lived and died. Missions like HiZ-GUNDAM, a satellite planned for launch in the 2030s by the Japan Aerospace Exploratio...
