The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.
The longest stage in a star's life cycle is the main sequence stage, where the star fuses hydrogen into helium in its core. This stage can last for billions of years for stars like the Sun.
Suns
Main sequence
Smaller, cooler stars like red dwarfs have the longest life spans of up to trillions of years because they burn their fuel slowly. In contrast, massive stars like blue giants have much shorter life spans of only a few million years.
The 'main sequence' which is also a fusion of hydrogen atoms in the atmosphere.
Main sequence
Smaller stars, such as red dwarfs, have the longest life spans, on the order of tens to hundreds of billions of years. Larger stars, like blue giants, have much shorter life spans, typically only a few million years.
White dwarf stars are theorized to be the final evolutionary state of all stars that did not become neutron stars. This stage is the longest in a stars life outside of black dwarfs which are white dwarfs that have cooled dramatically.
Why don't you fly into space and ask one.
stars have life stages, but it takes millions of years to go to another life stage for the shortest lived stars and much longer for others.
The main sequence phase represents the longest period of time in a star's life cycle, during which the star fuses hydrogen into helium in its core. This phase can last billions of years, depending on the mass of the star.
Most stars are classified as main sequence stars, including our Sun. Main sequence stars are in a stable stage of nuclear fusion, converting hydrogen into helium in their cores. This is the longest stage in a star's life cycle, lasting for billions of years.
