Starlight is the light that comes from faraway stars, just like how a lamp shines light into your room.
Imagine you're in a dark room with a flashlight. When you turn it on, the room gets bright because the light travels from the flashlight to your eyes. Stars work the same way, they are like super-distant flashlights in space that are constantly shining light towards us.
How does starlight get here?
Stars are very far away, sometimes hundreds of thousands of miles (or even billions of miles) away! But even though they're so far, their light still makes it to Earth. It's like when you throw a ball across the room, no matter how far away your friend is, they can still catch it.
Why do we see starlight at night?
During the day, the Sun is shining brightly, and its light covers up the stars’ light. But when it gets dark, the Sun’s light goes away, and then we can see the stars, like tiny lights in the sky, because their light has finally reached our eyes.
So starlight is just light from a faraway star, traveling all that way to shine on us!
