| Detailed Caption | Gamma-Ray Bursts (GRBs) are flashes of gamma-rays from the explosions of the most massive stars. Their afterglows are extremely bright and span the entire electromagnetic spectrum. The X-ray afterglow of GRB090423 is shown here as detected by XMM-Newton only a few hours after the GRB exploded. At z ≈ 8.2, this GRB is the most distant known object, and lies during the epoch of reionisation, when the gas between galaxies was still partially neutral. | ||
