  1. 2. An object that orbits around a celestial body. Satellites can be natural, like moons, or artificial, which are human-made objects placed in space to perform specific tasks. Artificial satellites are used for communication, weather monitoring, navigation, and scientific research. They are launched into space by rockets and provide valuable data and services to people on Earth.
  2. 4. A natural satellite that orbits around a planet. Moons are smaller than planets and can have various shapes and sizes. Our planet Earth has one moon, which is an important celestial object that affects ocean tides and has been explored by astronauts. Moons can have diverse landscapes and provide opportunities for scientific research and space exploration.
  3. 5. A scientist who studies celestial objects, such as stars, planets, galaxies, and other phenomena in space. Astronomers use telescopes, satellites, and computer simulations to observe, analyze, and interpret data about the universe. They make important discoveries, develop theories, and deepen our understanding of the cosmos. Astronomers play a vital role in unraveling the mysteries of space and expanding our knowledge of the vastness beyond Earth.
  4. 7. Hole A region in space with an extremely strong gravitational pull that nothing, not even light, can escape from. Black holes are formed from the remnants of massive stars that have collapsed under their own gravity. They have a profound influence on their surroundings and play a crucial role in the structure and evolution of galaxies. While they cannot be directly observed, their effects can be detected and studied by scientists using specialized instruments and techniques.
  5. 9. A vehicle designed to travel and operate in space. Spacecraft can be manned or unmanned and are used for various purposes, such as scientific research, satellite deployment, and exploration missions. They are equipped with advanced technology to withstand the harsh conditions of space and carry out specific tasks. Spacecraft enable us to study distant objects, gather data, and expand our knowledge of the universe.
  6. 11. A small celestial object that enters Earth's atmosphere and burns up due to friction, resulting in a bright streak of light known as a shooting star. Meteors are often debris from comets or asteroids. They can be observed during meteor showers and provide a captivating display in the night sky. Studying meteors helps scientists understand the composition of celestial objects and their interaction with Earth's atmosphere.
  7. 13. Station A large structure or spacecraft designed to support human habitation and scientific research in space. Space stations orbit around the Earth and provide living quarters and workspaces for astronauts. They serve as bases for long-duration missions and enable scientists to conduct experiments in microgravity. Space stations are international collaborations and symbolize humanity's achievements in space exploration and cooperation.
  8. 14. A vast cloud of gas and dust in space. Nebulas are often regions where new stars are formed. They can have different shapes and colors, and some are visible from Earth. Nebulas are captivating subjects for astronomers and provide insights into the life cycle of stars and the dynamics of the universe.

  1. 1. An instrument used to observe distant objects in space. Telescopes can collect and magnify light, allowing astronomers to study celestial bodies that are far away. They come in different sizes and types, including optical telescopes and radio telescopes. Telescopes have revolutionized our understanding of the universe and continue to contribute to new discoveries and knowledge about galaxies, stars, and planets.
  2. 3. A large system of stars, gas, dust, and other celestial objects bound together by gravity. Galaxies can be spiral-shaped, elliptical, or irregular and contain billions or even trillions of stars. Our Milky Way galaxy is home to our solar system, and there are billions of other galaxies in the universe. Galaxies have diverse structures and play a crucial role in shaping the universe and providing a vast canvas for exploration and discovery.
  3. 6. A vehicle designed to travel through space. Rockets use propulsion systems to generate thrust and lift off from Earth's surface. They carry astronauts, satellites, and other cargo into space. Rockets have played a crucial role in space exploration and have allowed humans to reach the moon and send robotic missions to other planets. They are technological marvels and are essential for launching spacecraft beyond Earth's atmosphere.
  4. 8. A person who travels to space. Astronauts are highly trained individuals who conduct scientific research, perform experiments, and explore outer space. They travel in spacecraft and may spend time on space stations. Astronauts contribute to our understanding of space, help develop technologies, and inspire future generations to pursue careers in science and space exploration.
  5. 9. A luminous ball of hot gas that generates its own light and heat through nuclear fusion. Stars are present in galaxies and are incredibly far away from Earth. The Sun is the closest star to us and provides light and heat necessary for life on our planet. Stars come in different sizes, colors, and temperatures, and studying them helps scientists understand the universe's composition and evolution.
  6. 10. A celestial object composed of ice, dust, and rock that orbits around the Sun. Comets have distinct orbits and sometimes develop a visible coma (a glowing cloud) and a tail when they approach the Sun. They can be observed from Earth during certain periods and have fascinated people for centuries. Comets provide valuable information about the early solar system and its composition.
  7. 12. A celestial body that orbits around a star. Planets are large and spherical in shape and do not produce their own light but reflect the light of the star they orbit. There are eight known planets in our solar system, including Earth, which is the planet we live on. Planets can have unique features like atmospheres, moons, and different surface conditions. They are fascinating to study and provide insights into the vastness of the universe.
  8. 13. System The system consisting of the Sun, planets, moons, asteroids, comets, and other celestial objects that orbit around the Sun. Our solar system is just one among many in the universe. It formed approximately 4.6 billion years ago and provides a home for our planet, Earth. The study of the solar system helps us understand the dynamics of planetary systems, the conditions necessary for life, and the unique characteristics of our own celestial neighborhood.
