For centuries people have been studying the stars, searching for
answers as to their origin. It has only been in the last few decades
however that accurate data on the stars has been accessible. This has
come in the form of various telescopes and satellites which,
when combined, cover a good portion of the entire electromagnetic
spectrum of the radiation emitted from stars. As well as
traditional earth-based telescopes which study visible light and
radio telescopes which study radio waves, Some of the more
recent projects include:
- COBE: which stands for Cosmic Background Explorer,
studies microwave radiation.
- IRAS: which stands for Infrared Astronomical Satellite,
studies infrared radiation.
- HST: which stands for Hubble Space Telescope,
studies visible and ultraviolet light.
- ROSAT: which stands for Roentgen Satellite,
- GRO: which stands for Gamma Ray Observatory,
studies high-energy gamma rays.
