Imagine you're an astronaut, lost in the vast emptiness of space. But with just two stars and the knowledge of stellar parallax, you can find your way!

Stellar parallax occurs when the position of a star seems to shift in relation to other stars as you orbit around it. This phenomenon happens because every six months, our Earth is on opposite sides of the sun, giving us two distinct viewpoints. To experience this for yourself, try looking at a candle from different angles, first with only your left eye, then with only your right.

This cosmic trick can help you navigate in space where traditional compasses and landmarks are no help at all. So, if you find yourself lost among the stars, remember to use your own two eyes, and the power of parallax, to guide your way back to safety.

Just remember, when navigating in space, it's essential to have a sturdy ship, a sturdy stomach, and a boatload of curiosity!
