Welcome to the realm of red giants! These enormous stars exhibit fascinating characteristics and play a crucial role in the lifecycle of a star.
Red giants are stars that have exhausted the hydrogen in their cores and have started to burn helium. This phase causes the star to expand and cool, bringing about a red coloration. The transformation is a fascinating aspect of stellar evolution.
Did you know they can shine 1,000 to 10,000 times more luminous than the Sun? That's truly a spectacle!
Red giants are a part of a star's evolution when it moves off the main sequence. During this stage, stars increase in size significantly. Sometimes they become so massive that their outer layers are ejected, creating beautiful planetary nebulae. Check out our section on Planetary Nebulae for more spectacular insights!
