Across
  1. 2. - A sudden brightening of a star, often resulting from a thermonuclear explosion on its surface.
  2. 5. - The study of the potential for life elsewhere in the universe and the conditions that support it.
  3. 6. Hole - A region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.
  4. 9. - An optical instrument that magnifies distant objects, allowing astronomers to observe celestial bodies.
  5. 11. System - The collection of the Sun and all celestial bodies that are gravitationally bound to it, including planets and asteroids.
  6. 13. - A unit of distance that represents how far light travels in one year, approximately 5.88 trillion miles.
  7. 16. - A large cloud of gas and dust in space, often the birthplace of stars.
  8. 18. - A vast system of stars, gas, dust, and dark matter bound together by gravity.
  9. 19. - A luminous celestial object made of plasma, producing energy through nuclear fusion.
  10. 21. Horizon - The boundary around a black hole beyond which nothing can escape the gravitational pull.
  11. 22. - The range of different colors produced when light is dispersed, often used to analyze the composition of stars.
  12. 25. - A small celestial body made of ice, dust, and rocky material that, when close to the Sun, develops a glowing coma and tail.
  13. 26. - A band of the sky divided into twelve signs, each associated with a particular constellation and used in astrology.
  14. 29. - A powerful and luminous explosion marking the death of a star, often outshining entire galaxies for a brief period.
Down
  1. 1. - The branch of astronomy that deals with the physical properties and processes of celestial objects and phenomena.
  2. 3. - The universe seen as a well-ordered whole, encompassing all celestial bodies and phenomena.
  3. 4. Bang - The leading scientific explanation for the origin of the universe, suggesting it began from a singular point and expanded rapidly.
  4. 7. - A small rocky body that orbits the Sun, primarily found in the asteroid belt between Mars and Jupiter.
  5. 8. - Pertaining to the Moon; often used to describe phenomena or features related to it.
  6. 10. - An event where one celestial body moves into the shadow of another, temporarily obscuring it.
  7. 12. - The phenomenon where light from an object moving away from an observer is shifted to longer wavelengths, indicating expansion of the universe.
  8. 14. - A planet that orbits a star outside our solar system.
  9. 15. - The curved path of a celestial body around a star, planet, or moon due to gravitational forces.
  10. 17. - A celestial body that orbits a star, is spherical in shape, and has cleared its orbit of other debris.
  11. 18. - The force of attraction between two masses, fundamental in shaping the structure and dynamics of the universe.
  12. 20. - A group of stars that form a recognizable pattern in the night sky, often named after mythological figures.
  13. 23. - A small rock or particle from space that burns up upon entering Earth’s atmosphere, creating a bright streak of light.
  14. 24. - A highly magnetized rotating neutron star that emits beams of radiation, observed as regular pulses.
  15. 27. - A natural or artificial body that orbits a planet or larger celestial body.
  16. 28. - A highly luminous and distant object powered by a supermassive black hole, emitting massive amounts of energy.
