Space is the boundless, three-dimensional expanse that exists beyond Earth’s atmosphere and between celestial bodies. It operates as a near-perfect vacuum filled with plasma, electromagnetic radiation, cosmic rays, and dust, fundamentally serving as the stage where all physical objects and events occur.

Key Concepts and Exploration

• The Cosmos: The universe beyond Earth is heavily researched by organizations like NASA Science. It features galaxies, stars, exoplanets, and dark matter, which are continually studied using observatories like the James Webb Space Telescope.
• Spaceflight & Exploration: Launch operations and missions (such as NASA’s Artemis program) push human boundaries. Commercial entities and international space agencies track missions and space exploration milestones via Space.com.
• Mathematical & Physical Space: In physics, space is viewed as part of a four-dimensional continuum known as spacetime.
