Why do stars only appear at night?

Answer: Sunlight overpowers starlight

Stars turn off during daytime — Wrong. Stars shine continuously. They're invisible during day because the sun's scattered light in our atmosphere is much brighter than distant starlight.

Stars move to night side of sky — Wrong. Stars don't move to the night side. The same stars are above us day and night—they're just overwhelmed by scattered sunlight during the day.

Sunlight overpowers starlight ✓ — Correct! Stars are always there, but during day, the sun illuminates Earth's atmosphere. Rayleigh scattering creates a bright blue sky that's far more intense than distant starlight (except the sun). Our eyes can't detect stars against this brightness. At night, no scattered sunlight—stars become visible!
