WebIn this lesson plan from WorldWide Telescope Ambassadors, students explore objects representing various stages of the stellar life cycle and uncover how these stages fit together into two related sequences: one for Sun-like stars (similar in mass to our Sun) and one for massive stars (more than 8 to 10 times the mass of our Sun). This resource was … WebMain Sequence Stars A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood. Our Sun will stay in this mature phase (on the main sequence as shown in the Hertzsprung-Russell Diagram) for approximately 10 …

WebThe life of a typical star starts when a giant gas cloud begins to collapse under its own gravitational attraction. As the particles and atoms fall towards each other, they speed up and their temperature rises. Eventually, the temperature becomes sufficient for the forming star to begin radiating visible light at the red end of the spectrum ... During this stable phase in the life of a star, the force of gravity holding the star together is balanced by higher pressure due to the high temperatures. The Sun is at this stable phase in its life. Pogledajte više A star forms from massive clouds of dust and gas in space, also known as a nebula. Nebulae are mostly composed of hydrogen. Gravity begins to pull the dust and gas together. Pogledajte više When all the hydrogen has been used up in the fusion process, larger nuclei begin to form and the star may expand to become a red giant. Pogledajte više As the mass falls together it gets hot. A star is formed when it is hot enough for the hydrogen nuclei to fuse together to make helium. The fusion process releases energy, which … Pogledajte više When all the nuclear reactions are over, a small star like the Sun may begin to contract under the pull of gravity. In this instance, the … Pogledajte više tidewater community college employment
