Many other stars are visible to the naked eye at night Their immense distances from earth make them appear as fixed points of light. The meaning of star is a natural luminous body visible in the sky especially at night How to use star in a sentence. At the beginning of the end of a star’s life, its core runs out of hydrogen to convert into helium The energy produced by fusion creates pressure inside the star that balances gravity’s tendency to pull matter together, so the core starts to collapse.
Throughout the milky way galaxy (and even near the sun itself), astronomers have discovered stars that are well evolved or even approaching extinction, or both, as well as occasional stars that must be very young or still in the process of formation. These large, swelling stars are known as red giants But there are different ways a star’s life can end, and its fate depends on how massive the star is. In a very broad sense, a star is simply one of those twinkling points of light you can see in the night sky But that’s not terribly satisfying in either lexicological or physical terms. A star is a huge sphere of very hot, glowing gas
Fusion happens when lighter elements are forced to become heavier elements When this happens, a tremendous amount of energy is created causing the star to heat up and shine Stars come in a variety of sizes and colors.
