![Global map of Enceladus with color and contours indicating the estimated heat flux (in mWm−2 ) calculated from maps of shell thickness [Hemingway and Mittal, 2019]. Our results (Table 1) are plotted as lines using the same color scale as the background. Green labeled boxes show other estimates [Giese et al., 2008; Bland et al., 2012, 2007; Leonard et al., 2021] of paleo-heat fluxes using similar methods.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Paleoheat.png?resize=1200%2C721&ssl=1)
[astro-ph.EP] Saturn’s moon Enceladus has active plumes suggestive of locally high heat fluxes at present, and the present-day heating is reasonably well characterized. However, the moon’s thermal history is not […]
