Why is the sun yellow?Warning: To protect your eyes, do not look directly at the sun. What color is the sun? Is it the same color in the middle of the day as it is at morning and evening? To many people, the sun seems yellow in the day, and can be more red around sunrise and sunset. The sun is a star just like the rest of them, but it's close enough to look much larger and brighter, and to provide most of the energy for life on our planet. So if the sun is a star, and the stars look white, then why isn't the sun white too? Are stars really all white? You can find out for yourself. On a clear night, go to a dark place far from city lights. Look carefully at the stars with a pair of binoculars. You might see some stars that are red, yellow or even blue. The color is related to temperature. Medium temperature stars, like our sun, are mostly yellow. Is the sun only yellow? If so, then how can we see green, red and other colors here on earth? If you want to see all the colors of the sun, spray a garden hose in your lawn in the morning or afternoon. Hold your thumb over the end to get a wide spray. Can you see a rainbow? If you want to see all the colors that really come from the sun, look at this. Want to know more about the color of the sun and stars?
