Miranda’s Unlikely Ocean Has Us Asking If There’s Life Clinging On Around Uranus

If you’re interested in extraterrestrial life, these past few years have given an embarrassment of places to look, even in our own solar system. Mars has been an obvious choice since before the Space Age; in the orbit of Jupiter, Europa’s oceans have been of interest since Voyager’s day; the geysers of Enceladus give Saturn two moons of interest, if you count the possibility of a methane-based chemistry on Titan. Even faraway Neptune’s giant moon Triton probably has an ocean layer deep inside. Now the planet Uranus is getting in on the act, offering its moon Miranda for consideration in a kinda-recent study in the Planetary Science Journal.

Possible Discovery Of Liquid Water In Mars’ Mid-Crust By The Insight Lander

One of the most sought after substances in the Universe is water – especially in its liquid form – as its presence on a planet makes the presence of life (as we know it) significantly more likely. While there are potentially oceans worth of liquid water on e.g. Jupiter’s moon Europa, for now Mars is significantly easier to explore as evidenced by the many probes which we got onto its surface so far. One of these was the InSight probe, which was capable of a unique feat: looking inside the planet’s crust with its seismometer to perform geophysical measurements. These measurements have now led to the fascinating prospect that liquid water may in fact exist on Mars right now, according to a paper published by [Vashan Wright] and colleagues in PNAS (with easy-read BBC coverage).
