The life cycle of a star

Another process is the CNO cycle where carbon is converted into nitrogen, then oxygen, which convert hydrogen into helium. What happens is that the pressure once stabilized by nuclear fusions will become weaker than the powerful force of gravity, which causes the star to start collapsing on itself.

The Sun will then shrink to around 10 times its current size and 50 times its luminosity, with a temperature a little lower than today. A New Beginning A nebula created from the life cycle of a star will continue to expand for millions or billions of years.

Planets in the Outer Solar System are likely to change dramatically, as more energy is absorbed from the Sun, causing their water ices to sublimate — perhaps forming dense atmosphere and surface oceans. A large enough star will continue further nuclear fusions and chain producing heavier elements, up to iron.

A star about 1. A supernova may occur.

Magnetic activity can also emit energetic bursts of particles called stellar flares. Every star produces a stellar wind of neutral and charged gas particles blowing into space. This is the beginning of a star, and the beginning of the phase called the main sequence.

In the meantime, we have plenty of days of sunshine to look forward to! Red giants also have low temperatures at the surface but have high luminosity because of their large size. Once it acquires critical mass it will be able to support nuclear fusion.

This process would continue, with the Sun consuming heavier and heavier fuel in concentric layers.

Game: The Life Cycle of a Star

Our solar system, for example, was born from a second or third generation nebula that had an overabundance of heavy elements. And just a few million years later, it settled down into its current form.

What is the Life Cycle Of The Sun?

Final Phase and Death: One could say that we are made of star stuff. Life Cycle of a Star A star will typically form from a nebula, a gaseous cloud with some combination hydrogen, helium, and dust. The life cycle of the Sun had begun. As always, God or the Devil, depending on who you ask is in the details!

For the next million years, it will continue to burn helium in its core until it is exhausted. Most stars are too small in angular size to be examined with current telescopes.

All that would remain of the Sun would be a rapidly spinning neutron star, or maybe even a stellar black hole. But with the advent of modern astronomy, humans have become aware of the fact that the Sun is merely one of countless stars in our Universe.A star is a large mass of plasma matter held together by gravitational forces.

Near the end of its life a star can also have a significant portion of degenerate matter. Sun is the star nearest Earth. At night other stars become visible when not obscured by the Sun’s light or atmospheric interference.

LOVE these frog life cycle models. I like that it shows 5 stages instead of merely 4. I love how the eggs are slight see-through just like the real translucent eggs.
