The ability to routinely put such observatories in orbit has led to entirely
new fields of astronomy devoted to observations at wavelengths other than
visible. The following table summarizes some of the characteristic phenomena
that are studied at various wavelengths.
| Wavelength | Characteristic Object
|
| Gamma-Ray | Compact
object which collapsed
|
| X-Rays | Neutron
stars
|
| Ultraviolet | Hot
stars, quasars
|
| Visible | Stars
|
| Infrared | Red giant
stars, galactic nuclei
|
| Far-IR | Protostars,
dust, planets
|
| Millimeter | Cold
dust, molecular clouds
|
| cm Radio | HI 21-cm
line, pulsars

SkyView, which allows you to obtain views of different parts of the sky at
different wavelenghts.
