Reservoir of liquid water found deep in Martian rocks
Studies of quakes detected from the planet's surface found it in the planet's rocky outer crust.
Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet.
The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which touched down on the planet back in 2018.
The lander carried a seismometer, which recorded four years' of vibrations - Mars quakes - from deep inside the Red Planet.
Analysing those quakes - and exactly how the planet moves - revealed "seismic signals" of liquid water.

Is it really world news if it didn't happen on this world?
You're right. This belongs in Solar System News.
It happened on a world. 🤷🏻♂️
Mars is a world, it was never specified which world this community is about.
It is this world, just not this planet
That's generally what "world" means
I was in the impression that it's a much wider category
It's possible to use it to refer to a non-planet region (bigger or smaller) in a more general sense, but I wouldn't say that's the most common usage.
I guess it's like german "Realität"/"Wirklichkeit" (both meaning reality).
I understand "Realität" (reality) to mean something "real", like something touchable. Language, and literature are not "real" to me. They're "wirklich", but not "real".
