What are streaks of light moving across the sky?

Streaks of light moving across the sky are often meteors, commonly referred to as "shooting stars," which occur when small particles from space burn up upon entering Earth's atmosphere. These bright trails are the result of friction between the meteoroids and the air, causing them to glow. Additionally, some streaks may be man-made, such as satellites or space debris re-entering the atmosphere. In certain cases, they can also be related to atmospheric phenomena like auroras or lightning.
