#2It's around 100 light years away from Earth for anyone interested.

#3Based on those observations, the exoplanet appears to be about 70% larger than Earth with just five times its mass. That means it’s less dense than Earth
Seems like a rather large leap to go from that to "it's a water world", at least in these days where we get a "this new exoplanet may be covered in water!" headline every few months.

#4Is there a better source? “Freethink” seems to be confusingly mixing terms.
FWIW, we don’t have telescopes to resolve the surface of planets like this so they’re using inferences to approximate composition and extrapolating surface characteristics. Ie by these methods at a similar distance the statements are roughly equivalent to what we’d say of earth if we were seeing it at this distance. The crucial takeaway seems to be it might have a proper water cycle with or without surface rock.

#6A potentially worthy target for some atmospheric spectroscopy from JWST?

Let's gooo!

Programming machines to make the trip and then seeding with human life seems to be the best answer to distance.

That would be so interesting - could be many a sci-fi stories created on that premise.
Some mechanical robot/starship storing frozen embryos for 100 years to be released on a far-away exoplanet, the starship taking care of them while they grow up and learn how to live on this new world - the beginnings of a new civilization - a technological adam and eve of sorts.
