Carl Sagan Quotes

We're just one rock surrounded by this immense universe.

I put up my thumb and it blotted out the planet Earth.

There are more stars known to exist right now than the total number of all the grains of sand on every beach in the entire world. With those kinds of odds, it would seem downright naive for someone to go to a beach in, say, some out-of-the-way inlet in Baffin Bay, stoop to pick up only one tiny grain of sand, and declare that that grain alone was the only place where life could exist.

It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.

Space is almost infinite. As a matter of fact, we think it is infinite.

I want Carl Sagan to explain the sky to me.

The universe is a big place, perhaps the biggest.

I am very interested in the Universe - I am specialising in the Universe and all that surrounds it.

Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

I study the universe. It's the second oldest profession. People have been looking up for a long time.

Do not look at stars as bright spots only. Try to take in the vastness of the universe.

You cannot look up at the night sky on the Planet Earth and not wonder what it's like to be up there amongst the stars. And I always look up at the moon and see it as the single most romantic place within the cosmos.

I am an astronomer, and my job is to look to the heavens to better understand the universe and our place in it.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

There are 100 Billion starts in the galaxy. That used to be an astronomical number. It's less than the national deficit. Now we should calm them economical numbers.

I'm interested in the cosmos. I want to know what's out there and how connected we are.

I'm not really into sci-fi movies, but I'm into the science of space a lot. I love astronomy and thinking about the nothingness of the everythingness of space.

Space is a laboratory, an experiment in all forms of all things, an infinity of possibilities, properties, and places that cry out for investigation and exploration.

I've always been consumed by things that are out of this world, like space and moons.

Here we were, the only seven humans in space, repairing a telescope whose only purpose is to enrich the minds of people on planet Earth and increase our understanding of the workings of the universe. I can think of no better peaceful use of space for all humankind.

I don't know why. I'm fascinated with stars and space. I just love them.

We are discovering what the universe is really like, and it is totally magnificent, and one can only be inspired and awestruck by what we find.

The Hubble Space Telescope is more than remarkable. It has answered just so many of those fundamental questions that people have been asking about the cosmos since people were able to ask questions.

There is no stronger case for the motivational power of real science than the discoveries that come from the Hubble Space Telescope as it unravels the mysteries of the universe.

The stars are so far, far away!
