Big 9 Star life cycle
Text z Príbehu
- Stars are just like us made of elements and they are born and they die just like us. lets go through the life cycle of a star with a lot of mass. The star is made up of elements such as 98 percent hydrogen and helium. 1/3 of the hydrogen will turn into helium. A star does this for most of its life span
- A giant/supergiant star can make heavier items such as iron through there fusion. This is what the star does for only 10 percent of its life span. But that could be millions of years of less depending on the star.
- Got to take a picture.
- A star can die in three ways one is a supernova. A supernova happens when most of the outer layers of hydrogen and helium are ejected this also can included the heavier elements such as iron . Only 10 percent of its mass is left with the star.
- A second way is a black hole. A black hole happens when a stars core is so dense it collapses in on it self to make a hole so dense not even light can escape its gravitational pull. This Black hole can be three solar masses or larger.
- Come on flip back to right side up.
- The final way is personally my favorite way a neutron star. Its when the stars core collapses into a dense mass of neutrons. This can be one point four solar masses to three solar masses large.
- Who is he talking to?
- That's a stars life explained from birth just like us to death.
