Infrared thermographic image taken from FLIR Tools, showing an aggressive encounter between two juvenile pheasants (middle right of the image). The scale at the top indicates the color coding of temperatures, while the red, upwards-pointing triangles automatically pinpoint the maximum temperature within a selection box drawn manually around each pheasant’s head. Here, the aggressor on the left (Bx1), with a maximum head temperature of 37.5 degrees Celsius, has just delivered an aggressive peck to the recipient on the right (Bx2), who has a maximum head temperature of 35.7 degrees Celsius. The background reference temperature is 26.5 degrees Celsius, taken from a white plastic drinker filled with water (Sp1), suspended above the pen floor (top left of image).

Jupiter is shown in visible light for context underneath an artistic impression of the Jovian upper atmosphere’s infrared glow. The brightness of this upper atmosphere layer corresponds to temperatures, from hot to cold, in this order: white, yellow, bright red and lastly, dark red. The aurorae are the hottest regions and the image shows how heat may be carried by winds away from the aurora and cause planet-wide heating. Image credit: J. O’Donoghue, JAXA / Hubble / NASA / ESA / A. Simon / J. Schmidt.
