Astronomy is humanity’s oldest science. Long before the invention of telescopes, people looked up at the night sky and wondered about the Sun, the Moon, the stars and the wandering planets. Those first observations inspired questions that eventually transformed our understanding of the Universe.
Today, astronomy allows us to explore objects across unimaginable distances. From our own Solar System to distant galaxies billions of light-years away, every observation reveals new wonders and deepens our understanding of the cosmos.
The essays in this section explore the fascinating objects and phenomena that fill the night sky. They examine the lives of stars, the structure of galaxies, the nature of nebulae, the search for planets around other stars and the remarkable instruments that allow us to observe the Universe in ever greater detail.
Astronomy reminds us that the Universe is both vast and interconnected. Every star we see, every galaxy we discover and every new observation adds another chapter to the story of the cosmos—and to our own place within it.
Whether you are taking your first steps beneath the stars or have spent a lifetime exploring them, the night sky still has countless stories waiting to be discovered.
