  1. 7. A tool that uses lenses or mirrors to gather and magnify light from distant objects.
  2. 10. The change in the frequency of sound or light as an object moves closer or farther away.
  3. 14. ______ Velocity The speed at which gas is expelled from a rocket, creating thrust.
  4. 15. A method of combining data from multiple telescopes to create a more detailed image of space.
  5. 16. ________ Satellites: Man-made objects orbiting Earth, like GPS satellites.
  6. 17. A large group of billions of stars, gas, and dust bound together by gravity.
  7. 18. The distance light travels in one year, about 9.46 trillion kilometers.
  8. 19. A meteoroid that burns up as it enters Earth's atmosphere, creating a 'shooting star'.

  12. 29. A device that splits light into its colors (spectrum) to study the composition and properties of stars or planets.
  13. 31. A change in the color of light from a star due to its motion: ____ shift means moving away.
  14. 32. An ancient tool used to measure the position of stars and planets for navigation.
  15. 34. A telescope that detects radio waves instead of visible light, helping scientists study faraway objects in space.

  19. 39. ______ Satellites: Celestial bodies like moons.
  20. 41. How high an object is in the sky, measured in degrees above the horizon.
  21. 42. A stream of charged particles released by the Sun, which can affect Earth's magnetic field.
  22. 43. An outdated model of the universe where Earth is at the center, and all other celestial objects orbit it.
  23. 44. Rockets with multiple sections that drop off when their fuel is used up to make the spacecraft lighter.
  24. 45. A change in the color of light from a star due to its motion: ____ shift means moving closer.
  25. 46. Small, rocky objects that orbit the Sun, mostly found in the asteroid belt.
  26. 47. A flight path that reaches space but does not complete an orbit around Earth.
  27. 48. Phenomena that happen in the sky, like eclipses, meteor showers, or supernovas.
