5D Luke Donovan Why Stars are the Most Fascinating Part of S

Stars are cosmic energy engines that produce heat, light, ultraviolet rays, x-rays, and other forms of radiation.

They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles.

The nebula that was expelled from the star may continue to expand for millions of years. Eventually, the gravity of a passing star or the shock wave from a nearby supernova may cause it to contract, starting the entire process all over again. This process repeats itself throughout the universe in an endless cycle of birth, death, and rebirth. It is this cycle of stellar evolution that produces all of the heavy elements required for life. Our solar system formed from such a second or third generation nebula, leaving an abundance of heavy elements here on Earth and throughout the Solar System. This means that We are all made of star stuff. Every atom in our bodies was created either in the nuclear furnace of a star or in the cataclysmic explosion of a supernovas.

Polaris is always in the sky; it does not disappear depending on the season, which is one reason why it has been used for navigation for centuries. One of the brightest stars in the sky, Polaris is sometimes hard to see because it is 430 light years away. Polaris is also known as the North Star, the Northern Star, and the Lodestar, along with other titles. Some scientists think that throughout the centuries, Polaris has actually gotten brighter.
