Welcome to the Astronomical Society of South Australia

Looks at the Hertzsprung Russell (HR) Diagram which explains the relationship between luminosity, mass and temperature in stars during their various phases of evolution from a protostar and the main sequence through to red giants and white dwarfs.

The stars have fascinated humanity since the beginning of civilisation, from using them to track the different seasons, to relying on them to navigate thousands of kilometres on the open ocean. Our ancestors looked up in wonder at the night sky, the stars their constant celestial companions, and yet, nothing has captured the attention of mankind in history the way Stellar Death has. From the earliest Supernova in recorded history to present day, the life and death of stars continue to intrigue us. This session focuses on the birth of stars, how they differ in life, and their colossal, spectacular death.
