Listen to this lesson:

Imagine traveling through the vast expanse of space, where everything is dark and mysterious. But did you know that light behaves differently in space than it does on Earth? Light travels in waves, and in the universe, it splits into a fantastic array of colors, known as the light spectrum. Astronomers use special tools to view these cosmic colors to understand what stars and planets are made of. Each color tells a story about the temperature, size, and age of these celestial objects.

One of the most magical phenomena is when starlight passes through clouds of gas and dust, creating stunning rainbows that we call nebulae. Nebulae are like giant cosmic canvases painted with colors that range from deep reds to bright blues and greens. These colors aren't just beautiful; they also help scientists learn about the life cycle of stars and the materials found in the universe.

Next time you look at the night sky, think about the colors hidden in the stars' light that your eyes can't see. There’s a whole spectrum out there waiting to be discovered, and each hue is a clue to unlocking the mysteries of space.
