A Quote by Carl Sagan
A galaxy is composed of gas and dust and stars - billions upon billions of stars. Every star may be a sun to someone.

Listen my love, illumination is eternal. Now is always evolving. As there are billions of stars, there are billions of steps. As there are billions of souls, there are billions of ways to grow.
Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity.
The central region of the Milky Way, known as the bulge, is stuffed with literally tens of billions of stars. And most of these are old - considerably older than our Sun or its neighbors - because this part of the galaxy formed first. Consequently, bulge stars are generally deficient in heavy elements.
It is unlikely that we will ever see a star being born. Stars are like animals in the wild. We may see the very young, but never their actual birth, which is a veiled and secret event. Stars are born inside thick clouds of dust and gas in the spiral arms of the galaxy, so thick that visible light cannot penetrate them.
The reality is that we know that this universe, that our galaxy, has billions of stars. We know that stars have planets. So the likelihood that there is life somewhere else to me is just absolutely there.
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.
I never said it. Honest. Oh, I said there are maybe 100 billion galaxies and 10 billion trillion stars. It's hard to talk about the Cosmos without using big numbers. I said "billion" many times on the Cosmos television series, which was seen by a great many people. But I never said "billions and billions." For one thing, it's too imprecise. How many billions are "billions and billions"? A few billion? Twenty billion? A hundred billion? "Billions and billions" is pretty vague. When we reconfigured and updated the series, I checked-and sure enough, I never said it.
Whenever I saw the sun, I reminded myself that I was looking at a star. One of over a hundred billion in our galaxy. A galaxy that was just one of billions of other galaxies in the observable universe. This helped me keep things in perspective.
When the sun sets, beautiful though it may be, billions of stars appear. The ego is but one sun. When that sun sets, there are endless suns, endless horizons beyond it.
..because when we look up into the sky at night there will be no darkness, just the blazing light of billions and billions of stars, all falling.
There are more stars than there are people. Billions, Alan had said, and millions of them might have planets just as good as ours. Ever since I can remember, I’ve felt too big. But now I felt small. Too small. Too small to count. Every star is massive, but there are so many of them. How could anyone care about one star when there were so many spare? And what if stars were small? What if all the stars were just pixels? And earth was less than a pixel? What does that make us? And what does that make me? Not even dust. I felt tiny. For the first time in my life I felt too small.
A broad and ample road, whose dust is gold, And pavement stars,--as stars to thee appear Seen in the galaxy, that milky way Which nightly as a circling zone thou seest Powder'd with stars.
Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy.
Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.
We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering.
And when the universe has finished exploding all the stars will slow down, like a ball that has been thrown into the air, and they will come to a halt and they will all begin to fall towards the centre of the universe again. And then there will be nothing to stop us seeing all the stars in the world because they will all be moving towards us, gradually faster and faster, and we will know that the world is going to end soon because when we look up into the sky at night there will be no darkness, just the blazing light of billions and billions of stars, all falling.
