Why Do Comets Sparkle When They Reach the Sun?

Imagine a snowball that gets all sparkly when it’s near the fire. Comets are like those snowballs, but they travel through space and get super bright when they get close to the sun. The sun heats up the comet, making its ice melt into gas, which then glows in different colors, like a cosmic fireworks show!
