how star make there own light explain in points
Answers
Answer:
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.
Answer:
We can say that the stars emit light on their own because of "burning" but this burning is not like the usual burning of a paper. A star is a huge ball of gas called hydrogen. When two hydrogen nuclei fuse togetehr to form a helium nucleus some energy is released. This process is called nuclear fusion. The energy released in a fusion reaction heats up the other materials (other hydrogen and helium atoms ) nearby. This heating eventually grows out from the core to the outside. The radiation coming out of the star's surface is in the form of heat and light. Note that the hydrogen nuclei do not really burn: they only fuse to form helium and the energy released in the process is in the form of heat and light.
