Fig. 21 — Effect of spatial resolution on the appearance of plumes on Enceladus’ South Pole. Panel a: Cassini/ISS image taken on 21 Nov 2009 at 145° solar phase angle, with a pixel scale of about 0.8 km/px (published in Porco et al. 2014). Panel b: The same image of Panel A degraded in resolution to simulate a view at 5 km/px. Panel c: Enceladus plumes imaged by Cassini/VIMS at near-infrared wavelengths (about 1–2 μm), nearly simultaneously to the image in Panel A, but with a resolution of about 33 km/pixel. Panel d: Another near-infrared VIMS image of Enceladus plumes at a resolution of about 40 km/pixel along the vertical direction. In all panels, dashed orange lines indicate different tangent altitudes above the satellite limb (solid line)
