Personally, I believe that the discovery of liquid water is so important is because all forms of life need water to survive. :-), Ri
The discovery of liquid water on another planet would be important as it is a key ingredient for life as we know it. It could indicate the potential for past or present microbial life, and could provide insights into the planet's habitability and potential for supporting life in the future. Studying liquid water on another planet could also advance our understanding of planetary formation and evolution.
Neptune was confirmed as a planet close to its discovery in September 23, 1846. Mathematicians knew there was another planet there somewhere, it was found by mathematical prediction.
He was the first person to discovery another planet (Uranus) since ancient times.
Surface liquids indicate that there can be a gaseous atmosphere, as surface liquids and volatile ices are heated. Liquid hydrocarbons such as ethane show a very cold planet. Liquid sulfur shows a very hot interior. Liquid water shows a warm temperature, an indicator of possible lifeforms (on the surface or in the interior, under an ice shell).
It was the discovery of "Eris" (originally nicknamed "Xena").
An astronomical discovery is the discovery of anything outside of the planet earth and its atmosphere.

The discovery of Gliese d a habitable planet
The Miranda Rights and the Tree Ring Dating are some of the Arizona inventions. The discovery of the planet Pluto is another invention of Arizona.
The question seems poorly worded, but Earth is the planet with liquid water on its surface.
