All stars are born with Hydrogen making up 100% of their mass. As they spend their lives, the composition changes from star to star, depending on their masses.
Becuase nebulae tell us how stars get formed so the composition, density and size of a nebulae cloud says a lot about its age, likelihood of stars forming and the type of stars that might form.
hydrogen is what stars are mostly made Being the reservoir from which new stars are born in the Galaxy, interstellar matteris of fundamental importance in understanding both the processes leading to the formation of stars, including the solar system, and ultimately the origin of life in the universe. Stellar evolution stellar evolution is a necessary consequence of the physical theory of stellar-structure, which requires that the luminosity, temperature, and size of a star must change as its chemical composition changes because of thermonuclear reactions.ken mendozaPHIL.....
The way a massive star dies is determined by its mass. Stars with more than 8 times the mass of the Sun typically explode in a supernova, leaving behind a neutron star or black hole. Less massive stars, like the Sun, will eventually shed their outer layers to form a planetary nebula, leaving behind a white dwarf.
A diffuse mass of interstellar dust and gas is known as a nebula. Nebulae are often regions where new stars are forming, as the dust and gas are the raw materials from which stars are born. They can vary in size, shape, and composition.
They 'imprint' the chemical composition of the stretch of water where they hatch. Once they reach adulthood (after swimming in the oceans) they use this imprinted knowledge to 'home in' on the river where they hatched.
The first generation of stars is believed to have formed from pristine gas with fewer heavy elements compared to stars today, affecting their composition and behavior. Additionally, the first stars likely formed in different environments with higher densities and temperatures, influencing their size, mass, and lifespan. These differences may have led to the unique characteristics of the first generation stars compared to those born in the present universe.
New stars are being born all the time. The rate of star formation in the Milky Way is about 7 new stars a year.
jesus was not born from the stars he was born from the virgin mary
The stars throughout the disk.
Stars are born in a Nebula and die by burning out their energy.
Joseph Louis Proust was a chemist who was born in Angers, France in 1754. He is famous for showing that when a chemical reaction takes place, matter is not created, but it isn't destroyed either. This is referred to as the law of constant composition.
