For decades, science fiction authors have imagined scenarios in which life thrives on the harsh surfaces of Mars or our Moon, or in the oceans below the icy surfaces of Saturn’s moon Enceladus and Jupiter’s moon Europa.

![Fraction of different types of planets formed around stars in a grid with varying [Fe/H] and M∗. In order to form giant planets and super-Earths we require either a high metallicity or a high stellar mass. Further, water-rich planets are more common around stars with higher metallicities and stellar mass as these stars can sustain a high enough pebble flux outside the water ice line to form water-rich planets there. Earth-mass planets dominate for all metallicities and stellar masses as they do not require a high pebble flux in order to form. -- astro-ph.EP](https://astrobiology.newspackstaging.com/wp-content/uploads/2023/09/planetformation.png)
