The world where we live today is just a small
Ask: The world where we live today is just a small part of our universe. In your
previous years, you have learned about the different theories of the origin of
the universe that eventually led to the formation of galaxies, solar system
and other heavenly bodies. This lesson will focus on one of those wonderful
things present in outer space, the stars. Although stars are millions of light
years away from us, we can still see them twinkling in the night sky. Let’s
find out how they emit light and what keeps them shining for a long time.
please help me po
Answer:
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
