Jupiter-Io Montage
This is a montage of New  Horizons images of Jupiter and its volcanic  moon Io, taken during the  spacecraft’s Jupiter flyby in early 2007.  The Jupiter image is an  infrared color composite taken by the  spacecraft’s near-infrared imaging  spectrometer, the Linear Etalon  Imaging Spectral Array (LEISA) at 1:40  UT on Feb. 28, 2007. The  infrared wavelengths used (red: 1.59 µm, green:  1.94 µm, blue: 1.85 µm)  highlight variations in the altitude of the  Jovian cloud tops, with  blue denoting high-altitude clouds and hazes,  and red indicating deeper  clouds. The prominent bluish-white oval is the  Great Red Spot. The  observation was made at a solar phase angle of 75  degrees but has been  projected onto a crescent to remove distortion  caused by Jupiter’s  rotation during the scan. The Io image, taken at  00:25 UT on March 1st  2007, is an approximately true-color composite  taken by the  panchromatic Long-Range Reconnaissance Imager (LORRI), with  color  information provided by the 0.5 µm (“blue”) and 0.9 µm  (“methane”)  channels of the Multispectral Visible Imaging Camera (MVIC).  The image  shows a major eruption in progress on Io’s night side, at the  northern  volcano Tvashtar. Incandescent lava glows red beneath a  330-kilometer  high volcanic plume, whose uppermost portions are  illuminated by  sunlight. The plume appears blue due to scattering of  light by small  particles in the plume.
