starlight
The faint light that comes from stars in the night sky.
Starlight is the light that travels from distant stars through space to reach Earth. When you look up at the night sky and see those tiny points of light twinkling against the darkness, you're seeing starlight that has journeyed across unimaginable distances, sometimes for thousands or even millions of years.
Each star is actually a massive ball of burning gas, like our Sun, but so far away that we see only a faint glimmer of its light. The light from the nearest star beyond our Sun takes over four years to reach us, traveling at about 186,000 miles per second the entire way. Some of the starlight you see tonight left its star before you were born, before your parents were born, even before recorded history began.
Scientists study starlight carefully because it carries information about the stars themselves: their temperature, composition, age, and movement through space. By analyzing starlight through telescopes and special instruments, astronomers have mapped the universe and discovered planets orbiting distant stars.
The word also appears in poetry and songs to evoke beauty, romance, or wonder. When someone describes a starlit night, they mean one where the stars are clearly visible, their light illuminating the darkness in that particular way that makes you feel small and amazed at the same time.
