Infrared radiation
Infrared radiation is energy transfer via electromagnetic waves. These waves do not require particles to transfer energy thus they can travel through a vacuum, such as through space.
All objects emit infrared radiation. The hotter an object is, the more infrared radiation it emits within a given time.
Dark and matt surfaces are the best absorbers of infrared radiation however they are also very good emitters of infrared radiation. Light, shiny surfaces are good reflectors of it.
Therefore, a dark, matt surface will absorb heat energy at a faster rate than the same object that is light and shiny, yet it will also cool down more quickly because it is emitting heat energy at a faster rate.
