A Quote by Seth Shostak

The usual metric for whether a planet is habitable or not is to ascertain whether liquid water could exist on its surface. Most worlds will either be too cold, too hot or of a type (like Jupiter) that may have no solid surface and be swaddled in noxious gases.

In his eyes shone the reflection of the most beautiful planet in the Universe---a planet that is not too hot and not too cold; that has liquid water on the surface and where the gravity is just right for human beings and the atmosphere is perfect for them to breathe; where there are mountains and deserts and oceans and islands and forests and trees and birds and plants and animals and insects and people---lots and lots of people. Where there is life. Some of it, possibly, intelligent.

Stephen Hawking

In days gone by, scientists would speak solemnly about our solar system's 'habitable zone' - a theoretical region extending from Venus to Mars, but perhaps not encompassing either, where a planet would be the right temperature to have liquid water on its surface.

Titan has no liquid water on its surface, and any liquid water beneath its surface is inaccessible to us, as far as we know. It has hydrocarbon lakes, but we don't know of any organisms that could live in those, not at the temperatures that we find on Titan. Any reference to possible life in lakes on the surface of Titan is pure speculation.

Carolyn Porco

I would like to start by emphasizing the importance of surfaces. It is at a surface where many of our most interesting and useful phenomena occur. We live for example on the surface of a planet. It is at a surface where the catalysis of chemical reactions occur. It is essentially at a surface of a plant that sunlight is converted to a sugar. In electronics, most if not all active circuit elements involve non-equilibrium phenomena occurring at surfaces. Much of biology is concerned with reactions at a surface.

Walter Houser Brattain

Our best shot at finding life in our solar system might be to look at the moons of Jupiter and Saturn. Mars, increasingly, looks like a dead planet. But the oceans beneath the ice cover of the moons of Jupiter and Saturn may actually have more liquid water than the oceans of Earth.

Michio Kaku

If you have a glass full of liquid you can discourse forever on its qualities, discuss whether it is cold, warm, whether it is really and truly composed of H-2-O, or even mineral water, or saki. Meditation is Drinking it!

Taisen Deshimaru

Video looks like reality, it's more immediate, it has a verite surface to it. Film has this liquid kind of surface, feels like something made up.

Michael Mann

Jupiter is so big and its gravitational pull so strong that man would find it difficult to move about on the surface. The answer is to whittle it down to proper size with terrajets and nuclear power, using the debris to increase the size of Jupiter's moons so they, too, can be colonized.

Fritz Zwicky

It’s a marvelous thing, the ocean. For some reason when two people sit together looking out at it, they stop caring whether they talk or stay silent. You never get tired of watching it. And no matter how rough the waves get, you’re never bothered by the noise the water makes by the commotion of the surface - it never seems too loud, or too wild.

Banana Yoshimoto

There was no person, whether they thought I was too fat, too black, too country, too ghetto, too New York, too thug or too whatever! Nobody ultimately had the say over whether or not I was going to make it.

Kelly Price

If you keep at it long enough, one day you may witness some greater disturbance, some rushing breach of the water's surface so startling and violent and exhilarating that you too will suddenly, and always thereafter, believe in monsters.

Paul Schullery

Those who practice know whether realization is attained or not, just as those who drink water know whether it is hot or cold

Dogen

And then it gets so hot that they keep the supermarkets too cold. Hot, cold. Hot, cold. It gives me the runs." Mr. Landowsky

Janet Evanovich

Love, whether it's friendship or more, is like a cup. It fills up drop by drop, until one last drop and the cup is full. The liquid hangs there almost above the rim, hangs there on surface tension alone and you know that one more drop and it will spill over.

Laurell K. Hamilton

There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.

Bill Nye

If one's conscious life is too rigid, too regimented, then the surface may crack at times, and we are unprepared for the strange emotions or sensations we experience.

Anais Nin
