INTEGRAL's IBIS instrument captured the gamma-ray burst (GRB) of 19 December 2004 that Philippe Laurent and colleagues have now analysed in detail. It was so bright that INTEGRAL could also measure its polarisation, allowing Laurent and colleagues to look for differences in the signal from different energies. The GRB shown here, on 25 November 2002, was the first captured using such a powerful gamma-ray camera as INTEGRAL's. When they occur, GRBs shine as brightly as hundreds of galaxies each containing millions upon millions of stars.
