Have you ever wondered why stars come in so many colors? It all boils down to heat! Just like a hot object glows red before turning orange and then white-hot, stars radiate different colors depending on their surface temperature. The hottest stars burn with an intense blue or white light, while cooler stars appear dimmer and reddish. By analyzing a star's color, astronomers can actually estimate its scorching temperature, giving us a glimpse into the fiery heart of these celestial wonders.
