In addition to its use as a portable observatory, SOFIA flies high enough above nearly all the atmosphere’s water vapor, making it an ideal observer of infrared radiation (hence the “I” in its name). During its first-light flight on May 25–26, 2010, SOFIA captured a composite image of Jupiter at wavelengths of 5.4, 24, and 37 microns (colored blue, green, and red, respectively). The white stripe in the infrared image is a region of relatively transparent clouds through which the warm interior of Jupiter shines. A visual image of approximately the same side of Jupiter appears for comparison.
