Scientist Quotes

The most exciting thing that we have found with Cassini is the geological activity, the geysering activity at the south pole of Enceladus.
The need for a detailed, comprehensive examination of the Saturn system became clear during the early 1980s, after the two Voyager spacecraft made flybys of the planet. These celebrated events were the opening acts in the story of humanity's exploration of Saturn.
The questions that we scientist have about Saturn's rings are the questions that an ordinary person might be moved to ask when first seeing them, you know. What caused them? How did they get there? How long have they been around? How long are they going to last?
The reasons why images are so primal and people immediately relate to it is that we are exquisitely engineered to interpret information that is arrayed in two dimensions. That's our eyesight. That's how our eye-brain system works. So it immediately feels to us when we look at an image like we have extended our senses.
The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.
There's nothing in this world like being the first to discover some fundamental fact of nature. It's profoundly satisfying.
Those of us engaged in the practice of science come to feel a certain reverence for it, engendered by its demonstrable power to dissect, clarify, and explain what previously was unexplainable, and thus to improve the human condition.
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.
Titan is Saturn's largest moon, and, until Cassini had arrived, there was the largest single expanse of unexplored terrain that we had remaining in our solar system.
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.
To my mind, most people go through life recoiling from its best parts. They miss the enrichment that just a basic knowledge of the physical world can bring to the most ordinary experiences.
Voyager found Saturn to be a planet with a complex interior, atmosphere, and magnetosphere. In its rings - a vast, gleaming disk of icy rubble - the mission recorded signs of the same physical mechanisms that were key in configuring the early solar system and similar disks of material around other stars.
Voyager's passage through Saturn's inner system exposed diverse moons with dynamic forces at work. Titan, Saturn's largest moon, whose surface remained invisible through its thick, ubiquitous haze, nonetheless teased observers with hints of a possible ocean of liquid hydrocarbons.
We can have fun speculating about why things are the way they are but don't look to science to provide any answers.
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.
Whenever we humans think that we might be approaching something that is vaguely similar to Earth, we get very excited about it. The prospect of something familiar but yet so distant and so strange is a very exciting combination.
An asteroid impact in the worst case scenario is a terrifying thing. It seems very uncontrollable: in popular culture, it's often a metaphor for human powerlessness over the world.
An asteroid impact is a preventable natural disaster. It's in part preventable because we have the technology, and it's in part preventable because it's predictable.
Asteroids are our oldest and most numerous cosmic neighbors.
Astronomers are using every technique at their disposal to discover and study asteroids.
