Exploring the Cosmos
Space and astronomy address some of humanity's oldest questions: Where did we come from? Are we alone? What lies beyond our planet? The study of stars, planets, galaxies, and the fabric of spacetime combines observation, theory, and increasingly, direct exploration. From ancient sky-watchers to modern telescopes like Hubble and James Webb, we have steadily expanded our view of the universe. The field draws on maths and logic, physics, and engineering, with coding and programming playing a crucial role in data analysis and simulation.
From Our Solar System to the Edge of the Observable Universe
Our solar system contains eight planets, dwarf planets like Pluto, moons, asteroids, and comets. Beyond it, we find exoplanets orbiting distant stars, many in habitable zones where liquid water might exist. Galaxies hold billions of stars, and the observable universe contains billions of galaxies. Dark matter and dark energy dominate the cosmos by mass and energy, yet remain poorly understood. Exploring these frontiers requires collaboration across technology and science, with missions like Mars rovers and deep-space probes pushing the boundaries of human engineering.
Space has inspired literature and books, movies and TV, and gaming for generations. Sci-fi often drives public interest in real space exploration. The connection to mythology and folklore runs deep: many cultures have told stories about the stars, and constellations carry ancient names and narratives. For those drawn to big questions about existence, philosophy and astronomy have long informed each other.

Whether you follow launches, stargaze with binoculars, or dive into theoretical cosmology, space and astronomy offer a perspective that is both humbling and exhilarating. The universe is vast, ancient, and still full of mysteries waiting to be uncovered.
