Across
  1. 3. – This kind of system is mostly planets, moons, and asteroids. The Sun is the center of ours.
  2. 4. – all of space and time and everyhing in it
  3. 5. – This cluster of galaxies named after a Zodiac constellation approximately 53,000,000 light years from Earth.
  4. 6. – short for Transiting Exoplanet Survey Satellite
  5. 7. – Light travels in this form, but you can't surf them
  6. 8. what you do with math
  7. 11. – the distance that light can travel when it buzzes through space at 186,000 miles per second. It's about 5.88 trillion miles.
  8. 14. – the part of the spectrum of light we can see
  9. 16. – An object that follows 3 rules: 1) Go around the sun 2) have enough mass that gravity makes you spherical 3) no other space junk can be in your path
  10. 17. planet outside our solar system
  11. 20. – a rainbow-like band of colors.
  12. 21. the Space Telescope named after this astronomer launched in 1990 and is still teaching us about distant objects
  13. 22. – A giant ball of helium and other gases, held together by gravity, where nuclear fusion makes it shine brightly in the night sky
  14. 24. building blocks of molecules
  15. 25. a moon that orbits an exoplanet
  16. 27. a planet has to be located in this kind of zone to be habitable. Not too hot, not too cold
Down
  1. 1. – You have to have a telescope to call yourself this kind of building
  2. 2. – we measure this from one crest to the next, whether it's a unit of sound or light
  3. 3. – an apparatus for photographing or recording spectra.
  4. 9. – plural form of nebula, interstellar clouds of gas and dust where stars are born

  6. 12. Mars' atmosphere is made of this carbon gas we breathe out
  7. 13. a group of millions of stars plus gas, dust, and other objects
  8. 15. – an instrument that uses lenses and/or mirrors to gather and focus light for observation
  9. 18. the field we study at Griffith
  10. 19. NASA's new flagship space telescope, named after NASA's chief during the Apollo missions
  11. 23. – water, but in the air instead of a glass
  12. 26. – The you take when you're caught in a planet's gravity
