An illustration depicting GRB21106A. The event itself is seen as a white jet in the center of the frame, stemming from the merger seen as a pale blue lighted disk on the bottom left, and the shockwave afterglow is seen as a larger, semi-circular lit-up region toward the middle right. This artist's conception shows the merger between a neutron star and another star (disk, lower left) which caused an explosion resulting in GRB 211106A (white jet, middle), and left behind one of the most luminous afterglows on record (semispherical shock wave midright).
