The image is a <a href="https://en.wikipedia.org/wiki/Mollweide_projection" class="extiw" title="en:Mollweide projection">mollweide projection</a> of the temperature variations over the <a href="https://en.wikipedia.org/wiki/Celestial_sphere" class="extiw" title="en:Celestial sphere">celestial sphere</a>.The average temperature is 2.725 Kelvin degrees above absolute zero (absolute zero is equivalent to -273.15 ºC or -459 ºF), and the colors represent the tiny temperature fluctuations, as in a weather map. Red regions are warmer and blue regions are colder by about 0.0002 degrees.<br>This map is the ILC (Internal Linear Combination) map, which attempts to subtract out noise from the galaxy and other sources. The technique is of uncertain reliability, especially on smaller scales <a rel="nofollow" class="external autonumber" href="http://lambda.gsfc.nasa.gov/product/map/dr4/ilc_map_info.cfm">[1]</a>, so other maps are typically used for detailed scientific analysis
