Deep inside the morning sun, hydrogen is being fused into helium at temperatures of millions of degrees. X rays and gamma rays of incredible violence are pouring out of the core into the surrounding layers of the sun. If the sun were transparent, these rays would blast their way to the surface in a few searing seconds. Days, weeks, centuries, pass. Thousands of years later, that once deadly radiation finally emerges from the sun's surface as a gentle shower of yellow light-no longer a menace but just right for bathing earth with its warmth.
Every night is a miracle too.
Other suns twinkle at us across the vast expanse of our galaxy. They are a riot of colors, sizes, temperatures, and densities. Some are supergiants so large that if one were centered in the position of our sun, what remained of our planet would be inside the surface of that superstar. Other suns are tiny, white dwarfs-smaller than our earth, yet as heavy as our sun. Some will peacefully drone along for billions of years.
