3. Understanding Planetary Nebulae

Planetary nebulae represent a critical stage in stellar evolution, marking the end of a star’s life cycle. When stars similar in mass to our Sun exhaust their nuclear fuel, they shed outer layers of gas and dust, leaving behind a dense stellar core known as a white dwarf. The expelled material expands outward, illuminated by radiation from the central star, creating a luminous, colorful nebula. The Southern Ring Nebula exemplifies this phenomenon, showcasing vibrant layers of expelled material and a clearly visible central star, offering astronomers valuable insights into stellar death and regeneration.
