Mercury: The Desolate Planet

[@JohnSmith-gn9cn]

What a fantastic video! In addition to being crammed with fascinating information (with no time wasted for irrelevant nonsense, like most KZbin videos these days...), the delivery was excellent: clear, to the point and detailed. I also really like the background sounds and music, which gives it a welcome nostalgic feeling I can't really explain (similar to Sagan's Cosmos series). It was a genuine pleasure to watch this video - thank you! Subscribed, and I will enjoy watching your other videos.

I did enjoy watching it, learnt so many things. One questions though : why couldn't there be liquid water at he intersection of the light side and the dark side ? I doubt the temperature goes strait from 427°C to -175°C... could there be a 0-100 interval where it could exist ?

Bonjour! That's good thinking, however it looks like liquid water cannot exist on the surface at any temperature. This is because there is no air pressure on Mercury, and as the phase diagram for water shows, at 0 pressure it sublimates and never enters the liquid phase. astronomy.swin.edu.au/cosmos/s/sublimation If there is liquid water on Mercury, it has to exist below the surface, where it experiences pressure from overlying rock. We would probably need to land a robot on the surface to detect it. I hope this makes sense! :)
