A Quote by David Grinspoon

Titan has rivers and lakes of liquid methane and ethane, methane weather systems of clouds and storms that mirror Earth's hydrologic cycle, and seasonal cycles that rival Earth's in complexity.

Water-based life is very much an Earth-centric view, and we can push the envelope on that here in our own solar system. We have the methane seas of Titan.

Ellen Stofan

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

Our solar system is fantastically bizarre. There are worlds with features we never imagined. Storms larger than planets, moons with under-surface oceans, lakes of methane, worldlets that swap places...and that's just at Saturn.

Phil Plait

Smile O voluptuous coolbreathed earth! Earth of the slumbering and liquid trees! Earth of departed sunset! Earth of the mountains misty-topt! Earth of the vitreous pour of the full moon just tinged with blue! Earth of shine and dark mottling the tide of the river! Earth of the limpid gray of clouds brighter and clearer for my sake! Far-swooping elbowed earth! Rich apple-blossomed earth! Smile, for your lover comes!

Walt Whitman

We're pretty sure there's plenty of organic material on Pluto. The atmosphere is largely methane, and in sunlight, methane builds organic molecules. We see reddish stuff on the surface that we think is organic material.

David Grinspoon

Of course methane is a fossil fuel, but as long as it is burned efficiently and fugitive emissions of methane gas are minimised, it is a less harmful fossil fuel than coal and oil and is an important way-station on the global journey towards low-carbon energy.

Mark Walport

Titan is the one place in our solar system whose geographical and atmospheric diversity and complexity are rivaled only by the Earth's. It's very Earth-like, but it's also very different, which means we have a lot to learn as well as a prayer of understanding what we find.

Carolyn Porco

All indications are that three and a half billion years ago, Mars looked like Earth. It had lakes. It had rivers. It had river deltas. It had snow-capped peaks and puffy clouds and blue sky. Three and a half billion years ago, it was a happening place. The same time on Earth, that's when life started. So did life start on Mars?

John M. Grunsfeld

There has been evidence throughout history of cycles when the earth gets warmer and cycles when the earth gets colder. We should always be wise stewards of the earth and all of our natural resources. But as a policymaker, I won't be guided by the global warming propaganda machine. Al Gore - we need you to return your Nobel Peace Prize!

Raul Labrador

There is a lot of science in bubbles. They are just like our weather system. The earth is, in effect, trapped inside a liquid sphere, the troposphere, where our weather forms. The bright colors on the outside of a bubble are just varying thicknesses of bubble, just like the varying thicknesses of clouds.

Tom Noddy

Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal.

Thomas Friedman

For a Westerner to trash Western culture is like criticizing our nitrogen/oxygen atmosphere on the grounds that it sometimes gets windy, and besides, Jupiter's is much prettier. You may not realize its advantages until you're trying to breathe liquid methane.

Neal Stephenson

Earth walks on Earth, Glittering in gold; Earth goes to Earth, Sooner than it wold; Earth builds on Earth, Palaces and towers; Earth says to Earth, Soon, all shall be ours.

Walter Scott

I am shocked, truly shocked. I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes are forming everywhere and methane is bubbling up out of them.

Katey Walter

Earth and sky, woods and fields, lakes and rivers, the mountain and the sea, are excellent schoolmasters, and teach some of us more than we can ever learn from books.

John Lubbock

In celebration of this Earth Day, I encourage all Members of the House to support legislation aimed at investing in the improvement of water quality in our Nation's lakes, rivers, streams and estuaries.
