It includes ''imaging'', where a picture of some sort is made of the object; ''[[photometry (astronomy)|photometry]]'', where the amount of light coming from an object is measured, ''[[spectroscopy]]'', where the distribution of that light with respect to its [[wavelength]] is measured, and ''[[polarimetry]]'' where the [[polarisation]] state of that light is measured. An example of [[spectroscopy]] is the study of [[spectral line]]s to understand of what kind of [[matter]] light is going through. Visible astronomy also includes looking up at night ([[skygazing]]). Visible-light astronomy is part of [[optical astronomy]].
