A New Perspective on the Solar System
Our understanding of the Solar System has never been static. Every new observation, mission, and discovery helps us refine our knowledge, challenge old ideas, and reveal a richer and more dynamic picture of our cosmic neighbourhood.
Throughout history, our view of the Solar System has transformed dramatically, from an Earth-centred universe to a heliocentric system filled with planets, moons, asteroids, comets, and countless other worlds. More recently, space missions have reshaped our understanding of the origins of water and the building blocks of life, the nature and diversity of Solar System bodies, and humanity’s place within the cosmos.
This year’s 100 Hours of Astronomy celebrates the excitement of scientific discovery and invites everyone to explore the Solar System through a fresh perspective. Science is not a collection of fixed answers, it is an ongoing journey of curiosity, evidence, and discovery.
