Group One - Match the celestial body with its definition.
Celestial BodyDefinition
  1. rotating neutron star which generates regular bursts of radiation
  2. two stars that orbit around a common center of mass
  3. the imploded core of a massive star produced by a supernova explosion
  4. a component of the Universe made up of gas and a large number of stars held together by gravity
  5. an object whose gravity is so strong that even light can't escape
  6. a large ball of gas that creates and emits its own radiation


Group Two - Match the satellite with its definition.
SatelliteDefinition
  1. the third Small Astronomy Satellite that was used to determine the location of bright x-ray sources
  2. Roentgen Satellite, dedicated to the All Sky Survey, a joint German, British, and American venture
  3. the third Japenese x-ray mission in 1987-1991, carried the LAC (Large Area Counter)
  4. NASA's Small Astronomy Satellite launched from Kenya
  5. Compton Gamma Ray Observer in 1991-2000, it was NASA's Second Great Observatory to observe the EM spectrum
  6. Rossi X-ray Timing Explorer, studied time resolution of x-rays in combination with moderate spectral resolution to explore the variability of x-rays
  7. a British and American collaboration of an x-ray mission, monitored the x-ray sky from 1974-1980
