Understanding Red Giants: Stellar Evolution and the Future of Our Sun
A red giant is a luminous giant star of low to intermediate mass, representing a late phase in stellar evolution. As a star ages, the shell surrounding its core becomes hot enough to fuse protons into alpha particles, providing a new source of energy. This process causes the star to expand significantly, transitioning it into a red giant. In approximately four billion years, our Sun will undergo this transformation, showcasing the dynamic lifecycle of stars. Explore the fascinating journey of red giants and their importance in the cosmos.

Red giant • A Red giant is a luminous giant star of low or intermediate mass in a late phase of stellar evolution. • In a star the shell surrounding the central core becomes hot enough to fuse protons into alpha. So the star gains a new source of energy then soon after the heat causes the star to get bigger and then turn into a red giant. • The sun will turn into a red giant in about four billions years.
