Space is the vast, seemingly infinite expanse beyond Earth’s atmosphere, where celestial bodies like
stars, planets, moons, and galaxies exist. It begins at the Kármán line, approximately 100 kilometers
above Earth's surface. Space is a vacuum, devoid of air and matter, allowing light and electromagnetic
radiation to travel freely. The study of space, known as astronomy, has expanded our understanding of
the universe, revealing the origins of galaxies, black holes, and the possibility of life beyond Earth.
Human exploration, through missions to the Moon and Mars, continues to push the boundaries of
knowledge, offering insights into the mysteries of the cosmos.
