  1. 1. "An extremely luminous and distant celestial object that emits massive amounts of energy, believed to be powered by accretion onto a supermassive black hole"
  2. 4. Star, "Incredibly dense celestial object composed mainly of neutrons, formed from the remnants of a massive star after a supernova explosion"
  3. 8. "Force of attraction between objects with mass, responsible for holding planets in orbit around the Sun"
  4. 9. "Group of stars forming a recognizable pattern in the sky"
  5. 13. Hole, "Region in space with gravitational forces so strong that nothing, not even light, can escape its gravitational pull"
  6. 14. Magnitude, "Measure of the brightness of a celestial object as observed from Earth, taking into account its distance and intrinsic luminosity"
  7. 16. Giant, "Late-stage of a star's life cycle characterized by its expanded size and reddish color"
  8. 17. "Celestial object consisting of ice, dust, and gas, characterized by a bright coma and often a tail when near the Sun"
  9. 19. Galaxy, "A type of galaxy characterized by its spiral arms, containing stars, gas, and dust arranged in a spiral pattern around a central bulge"
  10. 20. Dwarf, "Remnant of a low- to medium-mass star after it has exhausted its nuclear fuel, characterized by its small size and high density"
  11. 21. "Early stage in the formation of a star, where a dense region of gas and dust begins to contract under its gravitational pull"
  12. 22. "The brightest star in the night sky"
  13. 23. "Rocky object that orbits the Sun, typically found in the asteroid belt between Mars and Jupiter"
  14. 25. "Relating to the interaction of electric and magnetic fields, encompassing a broad range of phenomena and waves, including light and radio waves"
  15. 26. "A small celestial body that enters the Earth's atmosphere, producing a streak of light due to friction with the atmosphere; often called a shooting star"
Down
  1. 2. "Explosive event marking the death of a massive star, resulting in a brilliant burst of light and the release of vast amounts of energy"
  2. 3. "Highly magnetized rotating neutron stars that emit beams of electromagnetic radiation, observed as periodic pulses of radiation"
  3. 5. Spectrum, "Range of all possible wavelengths of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays"
  4. 6. "Nuclear reaction that powers the Sun and stars"
  5. 7. "Apparent shift or change in the position of an object when viewed from different perspectives, used to measure distances in astronomy"
  6. 10. Star, "Pair of stars orbiting around their common center of mass"
  7. 11. Diagram, "Graph that plots the luminosity and temperature of stars, revealing their evolutionary stages"
  8. 12. "The tendency of an object to resist changes in its motion or rest"
  9. 15. Magnitude, "Measure of the intrinsic brightness of a celestial object, indicating its brightness as if it were located at a standard distance of 10 parsecs (32.6 light-years)"
  10. 18. "A measure of the amount of matter in an object or celestial body"
  11. 24. nebula, "Cosmic cloud from which our solar system formed"
