This animation illustrates one proposed explanation for GRB 250702B — the merger of a stellar-mass black hole with its stellar companion. As the black hole makes its last few orbits, it pulls large amounts of gas from the star. At some point in this process, the system begins to shine brightly in X-rays. Then, as the black hole enters the main body of the star, it rapidly consumes stellar matter, blasting gamma-ray jets (magenta) outward and causing the star to explode.
