What else can I help you with?
Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
What type of star burns helium?
Helium burning stars are called red giant stars. These stars have exhausted their core hydrogen fuel and have transitioned to fusing helium into heavier elements like carbon and oxygen.
Nearly 90 percent of all-stars are at what point in their life cycles?
Nearly 90 percent of all-stars are in the main-sequence phase of their life cycle. This is when they are fusing hydrogen into helium in their cores, a stable phase that can last for billions of years.
What is the source of stars energy?
Nuclear fusion, usually by fusing hydrogen-1 to helium-4.
What type of star forms the majority of visible stars in the sky?
The majority of visible stars in the sky are main sequence stars, like our own Sun. These stars are in the stable phase of their life cycle where they are fusing hydrogen into helium in their cores.
Stars produce energy by fusing hydrogen into?
Helium atoms
What types of stars are main sequence stars?
Any star that it fusing hydrogen into helium is classed as a main sequence star.
Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
Is a star born when helium and oxygen combine?
No. A star is born when hydrogen stars fusing.
What are the stars and how they formed?
Balls of incandescent (fusing) hydrogen gas that was brought together by gravity.
Are stars in the main sequence when nuclear fusion of any element is taking place?
No. Stars are only in the main sequence when they are fusing hydrogen.
What stars have left the main sequence?
The main sequence stars are stars that fuse hydrogen, so the stars that have left the main sequence are the ones that have basically run out of hydrogen. They are the Red Giant stars, Supergiant stars and White Dwarf stars.
Is hydrogen found in the universe formed by stars?
No. The hydrogen in the universe was formed during the Big Bang. Stars consume hydrogen, fusing it into helium.

What is the main energy source of stars?
Nuclear fusion, usually by fusing hydrogen-1 to helium-4.
Why is a star on the main sequence?
Because that is the period in a stars life when it is fusing hydrogen into helium See related question
