Across
  1. 4. A Terrestrial Planet with the largest volcanoes in the Solar System
  2. 5. A type of condition of a planet that inhibits the ability for life on that planet
  3. 7. The model of the Solar System where the Earth is the center point
  4. 9. The result of giving a black hole enough fuel
  5. 12. A part of the sun with very low density and with little light emission its not detectable under usual conditions
  6. 15. The method we use to detect the presence of various gases or material on a planet
  7. 18. What happens when the Earth, Sun and Moon are perfectly aligned
  8. 20. Bouncing Light off of mirrors to a sensor or eyepiece to capture what the telescope is looking at
  9. 21. A force that is responsible for the acceleration of the Universe causing it to Expand
  10. 24. The phenomenon where the galactic disk rotates about the center, with objects farther out orbiting slower and vice versa
  11. 28. A Type of low density planet that is mainly made of Gases with a solid core that is commonly made up of ice
  12. 29. The Point in which a star leaves the main sequence and starts to fuse a material into carbon
  13. 32. An equation named after an astrophysicist used to estimate the number of active "alien" civilizations
  14. 33. A Jovian Planet known for its "Great Red Spot"
  15. 34. How describe the phenomenon of objects emitting heat
  16. 35. The result of a hyper nova imploding upon its self into a "single point"
  17. 36. The point in which the star in its early stages starts to shrink and its density and temperature increase as a result
  18. 37. The final stage of a low-mass star where it becomes about the size of Earth and its only emission of light is from stored heat
Down
  1. 1. The first stage of the formation of Stars
  2. 2. How describe a galaxies shape that is not the traditional Elliptical or Spiral
  3. 3. A Jovian Planet best known for its rings
