   The star collapses by its own gravity and the iron core heats up. The core becomes so tightly packed that protons and electrons merge to form neutrons. In less than a second, the iron core, which is about the size of Earth, shrinks to a neutron core with a radius of about 6 miles (10 kilometers). The outer layers of the star fall inward on the ...

   Sep 16, 2020 · A visualization flying into the nebula Gum 29 and the star cluster Westerlund 2 at its core. All stars are born in clouds of dust and gas like the Pillars of Creation in the Eagle Nebula pictured below. In these stellar nurseries, clumps of gas form, pulling in more and more mass as time passes. As they grow, these clumps start to spin and heat up.

   What happens if a star dies?

   • Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upper layers. As the core contracts, it heats up.

   Why does a low-mass star collapse?

   • A low-mass star has a mass eight times the Sun’s or less and can burn steadily for billions of years. As it reaches the end of its life, its core runs out of hydrogen to convert into helium. Because the energy produced by fusion is the only force fighting gravity’s tendency to pull matter together, the core starts to collapse.

   What happens if the outer layers of a star expand?

   • As the outer layers expand, the radius of the star will increase and it will become a red giant. The radius of the red giant sun will be just beyond Earth's orbit. At some point after this, the core will become hot enough to cause the helium to fuse into carbon. When the helium fuel runs out, the core will expand and cool.

   What happens when a star explodes?

   • The star’s iron core collapses until forces between the nuclei push the brakes, and then it rebounds back to its original size. This change creates a shock wave that travels through the star’s outer layers. The result is a huge explosion called a supernova.

   What happens if a star squeezes its core?

   • But squeezing the core also increases its temperature and pressure, so much so that its helium starts to fuse into carbon, which also releases energy. The core rebounds a little, but the star’s atmosphere expands a lot, eventually turning into a red giant star and destroying any nearby planets.

    Mar 6, 2023 · Once gravity causes a star to collapse on itself, it will take another 100 million years for a star to deflate and form a persistent red cloud. Eventually, around 10 million years later, all that is left is a hot core of carbon and gasses that form a "planetary nebula." As the star further burns out, it will diminish into a white dwarf planet.
