The first images of black-hole environments. Their colours are brightness scales for radio light, not the colour of a surface.

    Supermassive black hole · Messier 87

    The first image of a black hole’s surroundings: radio light from hot gas around M87*, shown on an orange brightness scale.

Colours belong to the images and models they were sampled from, not permanently to an object. Positions in the colour atlas are colours, not places in space.
