NOIRLab put together a really cool interactive experience that lets you compare simultaneous Jupiter images at multiple wavelengths. The data were obtained at Hubble and Gemini North observatories.
CREDITS: I'm grateful to NOIRLab staff for producing the release, with special appreciation to Vanessa Thomas for patiently meticulous writing, Lars Christensen for the idea of doing an image comparison, and Mahdi Zamani for giving the Jupiter data his special touch of vitality and glamour. The Gemini data are from program GN-2016B-FT-18 (PI Wong) and the Hubble data are from program GO-14839 (PI de Pater). Observations and processing were described in Wong et al. (2020) and de Pater et al. (2019). This work was enabled by the location of the Gemini North telescope within the Maunakea Science Reserve, adjacent to the summit of Maunakea. I am grateful for the privilege of observing Ka'āwela (Jupiter) from a place that is unique in both its astronomical quality and its cultural significance.
I'm fascinated with the 2020 Great Conjunction, because (1) there is an entire word ("great conjunction") specifically reserved for when Jupiter and Saturn are in the same place in the sky, and (2) Hubble would be able to capture images of both of them in a single pointing. But this is just a dream, because the relative positions of the Earth, Jupiter, and Saturn means that the grand giants appear too close to the Sun for Hubble to target. Otherwise, a parallel exposure using HST's ACS and WFC3 cameras could have imaged both planets at the same time!
Friends have been asking me about this event, so here is some more info:
CREDITS: Timing and distance information comes from JPL Horizons, where geocentric observer position was selected. The simulated sky image was generated by the JPL Solar System Simulator, and the instrument footprints themselves were taken from the WFC3 Instrument Handbook. Gordy Bjoraker generated the solar system perspective view using the open-source Cosmographia visualization tool.
