Frequently Asked Questions
Why do stars twinkle at night?
Stars twinkle because their light travels through different layers of Earth's moving air, which bends the light before it reaches our eyes.
Why doesn't the Moon look the same every night?
The Moon does not make its own light; it reflects sunlight. As it moves around Earth, we see different amounts of its lit side, causing the phases.
Why can't we see stars during the day?
The Sun's light is so bright during the day that it scatters in Earth's atmosphere, hiding the much dimmer light of distant stars.
