A Quote by Carolyn Porco

No matter how you measure it, whether you measure the amount of mass or you measure the number of bodies, most of our solar system exists out beyond the orbits of the asteroids. So we could not have claimed to know our own solar system until Voyager had toured the giant planets.
Small bodies in our solar system, like comets and asteroids, help us understand how the solar system formed and provide opportunities to advance exploration.
The Moon and Mars were the two most likely candidates for life in the solar system; what exists beyond our solar system is mere guesswork.
Most of the solar system resides beyond the orbits of the asteroids. There is more to learn there about general planetary processes than on Mars.
The gas-giant planets in our solar system all have large moons.
What do we measure when we measure time? The gloomy answer from Hawking, one of our most implacably cheerful scientists, is that we measure entropy. We measure changes and those changes are all for the worse. We measure increasing disorder. Life is hard, says science, and constancy is the greatest of miracles.
Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.
When I grew up as a kid, we didn't know there were any other planets outside of our own solar system. It was widely speculated that planet formation was an incredibly rare event and that it's possible that other planets just don't exist in our galaxy, and it's just this special situation where we happen to have planets around our sun.
How can I be secure? Through amassing wealth beyond all measure? No. And what's beyond measure? That's a sickness. That's a trap. There is no measure. Only greed.
Despite the immense distance between our own solar system (including the earth) and the nearest other solar systems, a journey from one system to another is theoretically possible, once an unlimited source of power is developed.
There's no doubt that the search for planets is motivated by the search for life. Humans are interested in whether or not life evolves on other planets. We'd especially like to find communicating, technological life, and we look around our own solar system, and we see that of all the planets, there's only one that's inhabited.
Racism itself is difficult to measure. We can measure hate crimes - which are absolutely an indicator. We can measure reports of discrimination. We can measure the number of times hateful words are being used across the Internet. Those things all help us measure racism, but it can sometimes be nebulous.
Proof of the black hole is a tremendous amount of mass inside a very small volume. There's 4 million times the mass of our sun within a region that's comparable to the size of our solar system.
We need to make sure that the Voyager probes carrying a record of human civilization speeding beyond our solar system remain an introduction to the world that sent them and not an epitaph for a civilization that caused its own ruin.
We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.
I used to be a strong believer that we would eventually colonize the solar system the way it's been done in science fiction many, many times: bases on the moon, Mars colonized, move out to the outer planets, then we go to the next solar system and build a colony there. I don't know now - I'm not as convinced that's the way it's going to pan out.
No one planet can tell us everything about the universe, but Neptune seems to hold more than its share of information about the formation of our own solar system - as well as the solar systems beyond.
