A Quote by Carolyn Porco

When the Voyager 2 spacecraft sped through the Saturnian system more than a quarter of a century ago, it came within 90,000 kilometers of the moon Enceladus. Over the course of a few hours, its cameras returned a handful of images that confounded planetary scientists for years.

A century ago the Spanish flu confounded scientists and devastated whole regions, but while today's society has air travel and an enormous, heterogeneous population, we also have antibiotics, fantastic communication networks and, perhaps most crucially, more data than ever.

The earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.

A few years ago, they [Neandertals] were thought to be ancestral to anatomically modern humans, but now we know that modern humans appeared at least 100,000 years ago, much before the disappearance of the Neandertals. Moreover, in caves in the Middle East, fossils of modern humans have been found dated 120,000-100,000 years ago, as well as Neandertals dated at 60,000 and 70,000 years ago, followed again by modern humans dated at 40,000 years ago. It is unclear whether the two forms repeatedly replaced one another by migration from other regions, or whether they coexisted in some areas

We have all been brought up with an ethical system of 2,000 years ago, an industrial-managerial system of 200-300 years ago, a statecraft system of 200 years ago, and so on. None of this is working very well for the requirements of a time as complex and variegated as our own. So we stand shuttering at the threshold, with no clear map.

One time there was a student at Punjab University in Lahore who came down with cancer and his friend came to me for help. I stood outside on the street in Lahore and asked the people in that city for help. Within four or five hours, I received more than 40 million rupees [more than US $670,000].

...the debate among the scientists if over. There is no more debate. We face a planetary emergency. There is no more scientific debate among serious people who've looked at the science...Well, I guess in some quarters, there's still a debate over whether the moon landing was staged in a movie lot in Arizona, or whether the Earth is flat instead of round.

Al Gore

That hemisphere of the moon which faces us is better known than the earth itself; its vast desert plains have been surveyed to within a few acres; its mountains and craters have been measured to within a few yards; while on the earth's surface there are 30,000,000 square kilometres (sixty times the extent of France), upon which the foot of man has never trod, which the eye of man has never seen.

Camille Flammarion

Cassini was an international undertaking, led by NASA and the European Space Agency and designed to be, in every dimension, a dramatic advance over Voyager. At the size of a school bus, it was bigger than Voyager and outfitted with the most sophisticated scientific instruments ever carried into the outer solar system.

Carolyn Porco

The Moon is a ball of left-over debris from a cosmic collision that took place more than four billion years ago. A Mars-sized asteroid - one of the countless planetesimals that were frantically churning our solar system into existence - hit the infant Earth, bequeathing it a very large natural satellite.

Seth Shostak

It's amazing to me that not only can we put a probe around Saturn and get images of its moons, but our math and physics are so freaking accurate we can say, "Hey, you know what? On this date at this time if we turn Cassini that way we'll see a moon over 2 million kilometers away pass in front of another one nearly 3 million kilometers away." Every morning, I have a 50/50 chance of finding my keys. That kinda puts things in perspective.

Phil Plait

The school children of New York State planted more than 200,000 trees within ten years from the time Arbor Day was recognized. Few similar efforts in years have been more thoroughly commendable than the effort to get our people practically to show their appreciation of the beauty and usefulness of trees.

Andrew S. Draper

Since the tragedy at Sandy Hook Elementary School three years ago, we have lost over 90,000 Americans to gun violence. This is a manmade crisis that needs to be treated as the public health epidemic it has become.

The scientists I looked up to at the beginning were not Latino. They were famous scientists of many years ago, like Madame Curie. Later, I realized that there were also, but a very few, Latino scientists. There were good ones, but very few, because there wasn't as much a tradition to be a scientist in our culture. But this is changing.

Mario J. Molina

As far as Europa goes, Europa very likely has an ocean under its surface. In that regard, Europa and Enceladus are on equal par. But on Europa, the ocean is at least several kilometers under the surface, and the moon is bathed in an intense radiation field.

Carolyn Porco

If there's a God, and we have all this evidence that there's evolution, but He created the world only 6,000 years ago - what is the best and most logical explanation to reconcile those two things? I came up with - He came up with it, of course - that all things are fakeable.

David Javerbaum

The Cox Committee found that the Chinese military acquired many of the technologies over the past seven years, although many of them had been targeted for acquisition for more than a quarter century.
