Artwork of a pulsar emitting beams of energy as it orbits a white dwarf; the warping of spacetime is depicted as the change in an imaginary grid around them. The pulsar is not to scale; the white dwarf is hundreds of times larger. ESO/L. Calçada

A computer simulation shows the light emitted from dust swirling at 30% the speed of light around a black hole. Incredibly strong gravity affects the path the light takes, creating the warped structure. Credit: ESO/Gravity Consortium/L. Calçada
