When the gases reach the radiative zone, things heat up and the whole process starts all over again. Sunspots are slightly cooler than the rest of the sun's surface, which makes them look darker. The photosphere is the layer that holds sunspots. Sunspots have a dark center called the Umbra and a lighter ring around the outside called the Penumbra. It takes 50 million years for the energy formed deep inside the sun to reach Earth.
Earth only gets one-billionth of the total energy produced by the sun.
One million Earths could fit inside the sun. Apollo was both the Greek and Roman god of the sun. He brought life-giving heat and light to Earth and was the patron god of musicians and poets. Kalmbach Publishing Co.
