Neil deGrasse Tyson Quotes

As a planetary system, Saturn holds the greatest promise for answering questions that have a far broader scientific reach than Saturn itself.

I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.

In future, children won't perceive the stars as mere twinkling points of light: they'll learn that each is a 'Sun', orbited by planets fully as interesting as those in our Solar system.

My field is called planetary science.

We should be ready to reach out beyond our planet and beyond our solar system to find out what is really going on out there.

I am very excited to be supporting one of the world's most visionary efforts to seek basic answers to some of the fundamental question about our universe and what other civilisations may exist elsewhere.

This plucky NASA telescope is able to find planets en masse. If you compare planet hunting to prospecting for gold, then Kepler is equivalent to trading in your trusty pan for a diesel-powered sluice box.

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.

A time will come when men will stretch out their eyes. They should see planets like our Earth.

I was a science fiction geek from an early age, enthralled by the questions of life in the universe. As I got older, I learned that space exploration was real. I wanted to get involved in that. I knew I wanted to be a scientist.

You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.

Just speaking for myself, I think the return of people to the Moon has a lot to offer for understanding the formation and evolution of terrestrial worlds; so would the exploration of near-Earth asteroids by people.

We go to learn about our solar system, to search for life, and to understand what happened to Mars so we avoid it ourselves.

I look forward to working with the NASA team to help enable new discoveries in our quest to understand our home planet and unravel the mysteries of the universe.

There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.

We're going to find Marses and maybe Earths out in the solar system's attic of the Oort Cloud and the Kuiper Belt.

There is every reason to think that in the coming years Mars and its mysteries will become increasingly familiar to the inhabitants of the Planet Earth.

I think I set myself on a course to become a scientist around about the time that Carl Sagan's 'Cosmos' series was on television, and there really was no going back for me at that point, and then I went on to study space science and then get my Ph.D., then go aboard and work in the European Space Agency.

Everybody has busy lives, but you can tell people, 'Go outside and look at the night sky. We've been able to demonstrate that every star you see probably has a planet around it.'

The public has an incredible capacity for appreciating the wonder of our planet, our solar system, our universe.

Thinking about the universe has now been handed over to specialists. The rest of us merely read about it.

Spectroscopy can probably answer the question, 'Is there anybody out there?' Are we alone?

Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world.

Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect.

When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.
