1. the concerned with the physical and chemical properties of
celestial bodies.
[WordNet 1.5]


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]
