emit light

It’s intellectually interesting to know that the faint gray smudge barely visible on the horizon is the result of literal pieces of the sun that have been blasted toward you at hundreds of miles a second, funneled into our atmosphere by Earth’s magnetic field and induced to emit light via graduate school physics concepts.

Many objects in space, including distant galaxies and planets, emit light on the electromagnetic spectrum.

Black holes do not emit light.

These defects can absorb and emit light in the visible range with well-defined optical transitions, and they can act as local traps for electrons.

Those headlights, on the ends of two of its arms, are more properly called photophores - organs that react a mix of substances with oxygen to emit light.
