Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

16. An element of a highly efficient - two-dimensional electronic light detector






17. 10^2 nm 10^7 nm






18. Stars orvits do not define the spiral patterns - instead they are density waves that move at slower speeds (arms are defined by young O and B stars and gas clouds)

22. Small moons that maintain the shape of rings around Saturn and Uranus






23. The Big Bang was not an explosion of matter into empty space - like the explosion of a bomb. Instead - it was an emergence of space and time filled with pure energy where before none of this was present. The point from which is emerged is called the






24. A two-filter measure of the color - and hence temperature - of a star.






25. Matter so dense that even light cannot escape its gravity






26. Largest moon in solar system - two differenet types of terrain - darker terrain is older - NOT ACTIVE SURFACE






27. Disk dust grains are made of all the elements that are not in gaseous form in space which blocks starlight and causes interstellar extinction

35. A repeated - periodic push or pull capable of summing into a larger push or pull






36. A galaxy sending out a stream of material from its nucleus






37. Formed from slow rotating clouds - collapsed quicker - initial star formation rate is high but died out - older - little rotation - look redder






38. Sulfurous volcanoes - pools of liquid sulfur - surface resembles cheese pizza ACTIVE SURFACE






39. Small moons that maintain the shape of rings around Saturn and Uranus






40. Dying large-mass stars lose their outer layers in a violent explosion creating large - chaotic remnants. these brighten like nova but are so much brighter and only occur ONCE PER STAR






41. A particle of light.






42. Either Io -Europa - Ganymede - or Callisto






43. Ganymede and Titan






44. Elliptical orbits that come inside orbit of the Earth.






45. A change in the wavelength of light caused by a motion between the observer and light (or wave) source (blue shift if getting closer - red shift if moving away)






46. A cool collection of gas and dust silhouetted against a brighter background of stars and/or gas






47. Any change in the speed or direction of an object's motion






48. The crust of a meteorite caused by its entry into Earth's atmosphere






49. A very dense - highly populated cluster of galaxies






50. Collections of young - hot stars
