  Astrophysics \As`tro*phys"ics\, n. [Astro- + physics.] (Astron.)
     The science treating of the physical characteristics of the
     stars and other heavenly bodies, their chemical constitution,
     light, heat, atmospheres, etc. It is a branch of astronomy.
     [1913 Webster]
  
     Note: Its observations were traditionally made with the
           spectroscope, bolometer, etc., usually in connection
           with the telescope. In modern times, radiotelescopes,
           infrared telescopes, X-ray and gamma ray detectors and
           neutrino detection equipment located deep underground
           are all put into service to observe and test theories
           about astronomical phenomena.
           [Webster 1913 Suppl. +PJC]
