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.
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
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”.
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.
