Space
Introduction to Space
Space is the vast, seemingly infinite expanse that exists beyond the Earth's atmosphere. It is home to stars, planets, galaxies, and other celestial bodies. The study of space, also known as astronomy, has fascinated humans for centuries and continues to be an area of active research and exploration.
Key Concepts in Space
- Galaxies: These are massive systems of stars, stellar remnants, interstellar gas, dust, dark matter, and other cosmic objects bound together by gravity.
- Planets: These are celestial bodies that orbit a star, are spherical in shape, and have cleared their orbit of other debris.
- Stars: These are luminous spheres of plasma held together by gravity. They produce energy through nuclear fusion reactions in their cores.
- Black Holes: These are regions of spacetime exhibiting gravitational acceleration so strong that nothing can escape from them, not even light.
- Space Exploration: This involves the use of astronomy and space technology to explore outer space.
Topics in Space Exploration
Space exploration encompasses a wide range of topics, including:
- Space telescopes
- Manned missions to space
- Robotic missions to other planets
- Study of exoplanets
- Search for extraterrestrial life
