Welcome back to Cosmos in a Pod! I’m your host, Amitesh, and today we’re unravelling one of the most awe-inspiring phenomena in the universe: the life cycle of stars. These cosmic creation engines shape galaxies and forge the elements that make up everything around us.

Episode Highlights:

The Birth of a Star

• Stars begin in stellar nurseries, dense clouds of gas and dust called nebulae.
• Gravity collapses regions of the nebula into protostars, where nuclear fusion ignites, giving birth to a star.

Main Sequence Stars

• The longest and most stable phase of a star’s life, fueled by hydrogen fusion.
• Smaller stars like red dwarfs burn for billions of years, while massive stars burn hotter and faster.
