Technical facts about this news release:

About the Object
Object Name: Jupiter
Object Description: Planet
Distance: The semi-major axis of Jupiter's orbit about the Sun is 5.2 Astronomical Units (778 million km or 483 million miles).
Dimensions: The planet has a diameter of roughly 88,789 miles (142,984 km) at the equator.
About the Data
IRTF Data: Other data used in this composite image were taken on April 5, 2007 with the NASA Infrared Telescope Facility (a 3.0 meter telescope at Mauna Kea, Hawaii). The image was taken through a medium-band filter centered at 2.3 microns; six exposures of 1 second each were taken with the NSFCam2 instrument.
HST Data: The Hubble data are taken from the HST proposal 10782: I. de Pater, M. Wong, P. Marcus, and X. Asay-Davis (University of California, Berkeley).
Instrument: WFPC2
Filters: 410 nm, 502 nm, and 673 nm
Exposure Date(s): May 11, 2007

These images are a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample various wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

410 nm blue
502 nm green
673 nm red
