Regarding the Revision (647397895) Undid 
 Hello, I would like to let you know that I am a new-born in the Wikipedia family and I do rely on the nurture from adult members like you!  I was, in fact, watching the Documentary & simultaneously looking if the article on Wikipedia needed any update/citation. In my contribution, the scientific analysis of the photographs from the Hubble leading to the best evidence yet of liquid water on Europa was my intended subject. I agree that the geysers were described with greater detail (& less drama!?) in the previous paragraph. Now I see that my mentioning of the height (twice as in Kilometer & Miles!!) has overshadowed the intended subject, huh!  Repetition was never the intention. If you've felt  that my contribution did not make any sense, then I am accepting it just in a way that a kid would accept decisions of elders in the family!  I hope to evolve in a better way with these experiences  -
