One thing I remember very clearly and was taught: You called your parents friends Mr. or Mrs. not by their first names like kids do now. It was a sign of respect.
Oxygen is the third most abundant element on the sun. The sun is, by mass, 73.4% hydrogen, 25% helium, 0.8% oxygen, and 0.8% various other metals. In astrophysics, the term "metal" refers to any element that is neither hydrogen nor helium
The Sun is basically a thermonuclear bomb with a built-in thermostat. Just as in a hydrogen bomb, hydrogen atoms are fusing together to make helium atoms and this nuclear reaction produces heat (along with the light that we see). If the reactions go on too fast, the Sun expands slightly (just like a balloon expands when you heat up the air in it). This slows down the reactions and then the Sun cools and contracts. If it contracts too much, the nuclear reactions speed up, and then the Sun heats up and expands again. So the Sun stays at the same temperature, burning its nuclear fuel at a steady rate. At the rate it is going, we have about 4 billion years left until the Sun burns out
