What Does It Take to Make a Star

A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas

What is needed to create a star?

Stars are born when pockets of gas and dust within interstellar molecular clouds exceed critical density and collapse under their own gravity. Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

What is a star made from?

Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Aside from our sun, the dots of light we see in the sky are all light-years from Earth.
