36 JANUARY-FEBRUARY 2021 ASTRO PUBLISHING scarred with impact craters, al- though relatively few compared to other moons of Saturn. It is thought that erosion has obscured most of the craters on Titan, similar to what has happened on Earth. Not only does studying Titan’s craters reveal the geomorphological processes on the moon, but the craters give an in- sight into the subsurface composi- tion as they carve out a small pocket in the surface. Anezina Solomoni- dou and colleagues have recently published a paper in Astronomy & Astrophysics which performs a de- tailed analysis of nine prominent craters on Titan. Analysing craters is a key way to study Titan’s interior and the atmospheric influence on the surface. “When we study the astrobiological potential of an ocean-bearing world Craters reveal Titan is still a dynamic world U sing data from the interna- tional Cassini-Huygens mission to Saturn and Titan, scientists have found that there are two dis- tinct types of craters on Saturn’s largest moon Titan that are still being shaped by erosion. Titan has a dense atmosphere, a subsurface ocean, and a surface adorned with mountains, lakes, dunes, and many other Earth-like features. It is also by ESA
