Detailed explanation-1: -Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space.
Detailed explanation-2: -What is a star? A star is a big ball of gas. It is not star-shaped. Stars give off heat and light.
Detailed explanation-3: -A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova.
Detailed explanation-4: -Most stars are made up of mainly two gases, which are hydrogen and helium.
Detailed explanation-5: -A star is a massive, luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun, which is the source of most of the energy on the planet.
