Earth Space Science Quotes & Sayings

Earth is not the only planet where there is life,' Sandra began.

I frowned. 'Well, yeah, the NASA thinks there are aliens in outer space, right? Or maybe in other planets. You into science?'

Sandra exchanged a confused glance with Janis. 'No,' she said slowly. 'I'm not particularly a science geek and I'm not talking about aliens or planets, Nashira, I'm talking about a star. — Deepika Kumaaraguru

A man that is of Copernicus' Opinion, that this Earth of ours is a Planet, carry'd round and enlightn'd by the Sun, like the rest of them, cannot but sometimes have a fancy ... that the rest of the Planets have their Dress and Furniture, nay and their Inhabitants too as well as this Earth of ours. ... But we were always apt to conclude, that 'twas in vain to enquire after what Nature had been pleased to do there, seeing there was no likelihood of ever coming to an end of the Enquiry ... but a while ago, thinking somewhat seriously on this matter (not that I count my self quicker sighted than those great Men [of the past], but that I had the happiness to live after most of them) me thoughts the Enquiry was not so impracticable nor the way so stopt up with Difficulties, but that there was very good room left for probable Conjectures. — Christiaan Huygens

The story of evolution is more dramatic, more compelling, more intricate than any creation myth. Yet like any creation myth, it is a tale of transformations, of sudden and spectacular changes, eruptions of innovation that transfigured our planet, overwriting past revolutions with new layers of complexity. The tranquil beauty of our planet from space belies the real history of this place, full of strife and ingenuity and change. How ironic that our own petty squabbles reflect our planet's turbulent past, and that we alone, despoilers of the Earth, can rise above it to see the beautiful unity of the whole. — Nick Lane

National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars. — Carl Sagan

It was killing him, seeing her this way. She was not meant to be uncertain, timid or fearful; the woman he knew exuded confidence so fiercely it might as well be a damn spiritual aura. He needed to fix this.

"It's time to adjust your perspective. You want to show the politicians on Earth they don't rule the galaxy? Well, let's show them. — G.S. Jennsen

Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science. The early warnings about technological dangers also come from science. — Carl Sagan

How controversial is for one to deny that men aren't from space while the Earth itself is in space? — Marcus L. Lukusa

Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future. — Clifford A. Pickover

Hypothesis The science Mermaids are related to aliens from outer space who settled areas of Earth deep under the ocean and eventually mated with fish. This hypothesis is "out there." No evidence exists to support it. Creatures that closely resembled mermaids once existed but are now extinct or rare. For instance, a now-extinct species of sea cows might have been mistaken for mermaids. If true, this hypothesis would only prove the existence of a different type of sea cow, not mermaids. Plus, it would not explain recent mermaid sightings. Mermaids once existed but are now extinct. No "mermaid" fossils have yet been found. Mermaid — Lori Hile

We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects. — Laurel Clark

The apologists for space science always seem over-impressed by engineering trivia and make far too much of non-stick frying pans and perfect ball-bearings. To my mind, the outstanding spin-off from space research is not new technology. The real bonus has been that for the first time in human history we have had a chance to look at the Earth from space, and the information gained from seeing from the outside our azure-green planet in all its global beauty has given rise to a whole new set of questions and answers. — James Lovelock

The science and technology which have advanced man safely into space have brought about startling medical advances for man on earth. Out of space research have come new knowledge, techniques and instruments which have enabled some bedridden invalids to walk, the totally deaf to hear, the voiceless to talk, and, in the foreseeable future, may even make it possible for the blind to "see." — Hubertus Strughold

Now, more than ever, we need people in space ... The events of September 11 show us how vulnerable we and our civilization are down here on Earth ... So let us use our strength, our awareness of mortality as a civilization, to do something truly lasting and earth-shaking for humanity. Let us join with the peoples and cultures of this planet, the diversities of its perspectives and religions and science, so we can leave it-not behind, but as a springboard to something better. — Paul Levinson

Another glorious feature of many modern science museums is a movie theater showing IMAX or OMNIMAX films. In some cases the screen is ten stories tall and wraps around you. The Smithsonian's National Air & Space Museu, the popular museum on Earth, has premiered in its Langley Theater some of the best of these films. 'To Fly' brings a catch to my throat even after five or six viewings. I've seen religious leaders of many denominations witness 'Blue Planet' and be converted on the spot to the need to protect the Earth's environment — Carl Sagan

The cosmic perspective not only embraces our genetic kinship with all life on Earth but also values our chemical kinship with any yet-to-be discovered life in the universe, as well as our atomic kinship with the universe itself. — Neil DeGrasse Tyson

I am merely an insignificant creature on a microscopic blue dot in the vastness of space. — Abhijit Naskar

Rocket Fever Grips Nation's Teenagers' cheers on enthusiastic newsreel, reflecting the nation's sudden reversal in attitude following the successful launch of Explorer-I into Earth orbit. Rather than being strange and threatening, outer space looks set to become the next big distraction after Elvis Presley and Davy Crockett hats. 'More and more teenagers are passing up rock and roll for a rocket role,' commentator Michael Fitzmaurice blithely remarks before very probably wishing he hadn't. — Ken Hollings

Geologists search for the meaning to be read into the piled-up strata of the earth much as a historian might turn the pages of an ancient, damaged manuscript. The astronomer seeks the answer to his questions in the depths of space. Still other men concentrate on the scriptures alone. The wise man searches all these and other sources, knowing that all are communications from the same divine source and certain that, if followed far enough, all will guide him back to the Divine Presence. — Henry B. Eyring

A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being? — Carl Sagan

A human life
Is the time that happens
while
The Earth takes a break
For you to live
between
Inhaling and exhaling your soul
from the un-endless space
Named infinity — Haidji

I saw the Earth, yes. I saw the colors so magnificent, so vivid, so real. It was hope so large and round, green and blue. — Hafsah Faizal

We do a lot of science on the space station. Over the course of the year, there'll be 400 to 500 different investigations in all different kinds of disciplines. Some are related to improving life on earth in material science, physics, combustion science, earth sciences, medicine. — Scott Kelly

When I was little, I had this science book. There was a section on 'What would happen to the world if there was no friction?' Answer: 'Everything on earth would fly into space from the centrifugal force of revolution.' That was my mood. — Haruki Murakami

The Apollo pictures of the whole Earth conveyed to multitudes something well known to astronomers: On the scale of the worlds - to say nothing of stars or galaxies - humans are inconsequential, a thin film of life on an obscure and solitary lump of rock and metal — Carl Sagan

This is a really big space station. We do a lot of various kinds of work here, different kinds of science experiments; we have over 400 different experiments going on at any one time in different areas, from basic science research to medical technology, that hopefully will benefit more people on Earth. — Scott Kelly

Lyn, this was the "Aha!" moment when Desta found another astonishing skeleton. Remarkably, it appeared utterly human but existed before humans walked the Earth. Clutched in its hand a small sphere attached to an elaborate gold necklace. The sphere was not like any material on Earth. Remember when I told you our origins might lie in the stars? Well, I think we found the answer in the Afar desert
Max — Linden Morningstar

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

The law of computers is the same as the law of the marketplace. The earth's atmosphere was divided up into a network of cubes, each reducible to a collection of points, and each point the product of a set of calculations. As far as science was concerned, this was the end of clouds, which were but a series of coordinates simulated in a space of greater than three dimensions. — Stephane Audeguy

Science is not a boy's game, it's not a girl's game. It's everyone's game. It's about where we are and where we're going. Space travel benefits us here on Earth. And we ain't stopped yet. There's more exploration to come. — Nichelle Nichols

On Titan the molecules that have been raining down like manna from heaven for the last 4 billion years might still be there largely unaltered deep-frozen awaiting the chemists from Earth — Carl Sagan

We will eventually build space science labs and hotels, prodding the capability for missions beyond the orbit of the Earth. Our space-hotel guests will be able to take breath-taking excursions, flying a couple of hundred feet above the Moon's surface in small two-man spaceships. In time, we will launch missions to Mars and beyond. — Richard Branson

How strange it was, I thought, that when the tiny though thousandfold beauties of the Earth disappeared and the immeasurable beauty of outer space rose in the distant quiet splendor of light, man and the greatest number of other creatures were supposed to be asleep! Was it because we were only permitted to catch a fleeting glimpse of those great bodies and then only in the mysterious time of a dream world, those great bodies about which man had only the slightest knowledge but perhaps one day would be permitted to examine more closely? Or was it permitted for the great majority of people to gaze at the starry firmament only in brief, sleepless moments so that the splendor wouldn't become mundane, so that the greatness wouldn't be diminished? — Adalbert Stifter

The views of the Earth are really beautiful. If you've ever seen a space IMAX movie, that's really what it looks like. I wish I'd had more time just to sit and look out the window with a map, but our science program kept us very busy in the lab most of the time. — David M. Brown

Moving in space, the atoms originally were individual units, but inevitable they began to collide with each other, and in cases where their shapes were such as to permit them to interlock, they began to form clusters. Water, air, fire, and earth, these are simply different clusters of the changeless atoms. — Democritus

There is good science you can do in space. There is stuff there you cannot do on Earth and we can gain understanding from it. — Helen Sharman

Science literacy is being plugged into the forces that power the universe. There is no excuse for thinking that the Sun, which is a million times the size of Earth, orbits Earth. — Neil DeGrasse Tyson

I have looked further into space than ever human being did before me. I have observed stars of which the light, it can be proved, must take two million years to reach the earth.
[Having identified Uranus (1781), the first planet discovered since antiquity.] — William Herschel

You know that song, 'Woodstock.' It says 'We are stardust.' And we are. We come from stardust. Everything on earth is just ashes. — Priscille Sibley

I myself have dreamed up a structure intermediate between Dyson spheres and planets. Build a ring 93 million miles in radius - one Earth orbit - around the sun. If we have the mass of Jupiter to work with, and if we make it a thousand miles wide, we get a thickness of about a thousand feet for the base.
And it has advantages. The Ringworld will be much sturdier than a Dyson sphere. We can spin it on its axis for gravity. A rotation speed of 770 m/s will give us a gravity of one Earth normal. We wouldn't even need to roof it over. Place walls one thousand miles high at each edge, facing the sun. Very little air will leak over the edges.
Lord knows the thing is roomy enough. With three million times the surface area of the Earth, it will be some time before anyone complains of the crowding. — Larry Niven

Looking out on the second day of our mission, I became aware that in the far distance, there was a distinctive-looking star. It stood out because, while all the other stars stayed exactly the same size and shape, this one got bigger and bigger as we got closer to it. At some point it stopped being a point of light and started becoming something three-dimensional, morphing into a strange bug-like thing with all kinds of appendages. And then, isolated against this inky background, it started to look like a small town.
Which is in fact what it is: an outpost that humans have built, far from Earth. The International Space Station. It's every science fiction book come true, every little kid's dream realized: a large, capable, fully human creation orbiting up in the universe.
And it felt miraculous that soon we'd be docked there, and the next phase of our expedition would begin. — Chris Hadfield

After a duration of a thousand years, the power of astrology broke down when, with Copernicus, Kepler, and Galileo, the progress of astronomy overthrew the false hypothesis upon which the entire structure rested, namely the geocentric system of the universe. The fact that the earth revolves in space intervened to upset the complicated play of planetary influences, and the silent stars, related to the unfathomable depths of the sky, no longer made their prophetic voices audible to mankind. Celestial mechanics and spectrum analysis finally robbed them of their mysterious prestige. — Franz Cumont

Once upon a time, people thought earth was flat-shaped.
Now I'm ready to perceive universe won't be as we think. — Toba Beta

You can't show me the Earth from space and fly right past the moon, entice me into this magical machine and invite me to come with you, and then ask me to stay behind! — Elizabeth Newton

Nobody can tell you about that sword all that there is to be told of it; for those that know of those paths of Space on which its metals once floated, till Earth caught them one by one as she sailed past on her orbit, have little time to waste on such things as magic and so cannot tell you how the sword was made, and those who know whence poetry is, and the need that man has for song, or know any one of the fifty branches of magic, have little time to waste on such things as science, and so cannot tell you whence its ingredients came. Enough that it was once beyond our Earth and was now here amongst our mundane stones; that it was once but as those stones, and now had something in it such as soft music has; let those that can define it. — Lord Dunsany

I do not personally want to believe that we already know the equations that determine the evolution and fate of the universe; it would make life too dull for me as a scientist ... I hope, and believe, that the Space Telescope might make the Big Bang cosmology appear incorrect to future generations, perhaps somewhat analogous to the way that Galileo's telescope showed that the earth-centered, Ptolemaic system was inadequate. — John N. Bahcall

Don't you see what's at stake here? The ultimate aim of all science to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet. — Walter Reisch

A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time. — Carl Sagan

He (Comings) has in the past performed successful energy-converting experiments, creating a ringing resonance by injecting certain frequencies into piezo-electric crystals. When the crystal was in resonance with the plenum of space, the power output rose significantly higher than the input. He concluded that, if allowed politically, such discoveries could guide humankind in building a completely clean energy infrastructure -- resonant technologies that allow us to live in harmony with the universal energy field and the Earth. — Jeane Manning

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more. — Martin Rees

Modern science says: 'The sun is the past, the earth is the present, the moon is the future.' From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom. — Nikola Tesla

The Earth is cylindrical, three times as wide as it is deep, and only the upper part is inhabited. But this Earth is isolated in space, and the sky is a complete sphere in the center of which is located, unsupported, our cylinder, the Earth, situated at an equal distance from all the points of the sky. — Anaximander

People say- 'NASA lies.' I say- 'the moon knows it all. Look at the moon and forget the spinning flat world. — Munia Khan

We're doing it wrong, absolutely wrong! Miss Universe should be about Space Exploration, Miss World about Science and Miss Earth about Going Green! — Manasa Rao

Why travel to the Moon or Mars if we only continue our wars there with Russia or China or Africa? Why build rockets at all? For fun? For adventure? Or is this the same process that sends the salmons back upstream year after year to spawn and die - a subliminal urge in mankind to spread, in self-preservation, to the stars? Are we then secretly fearful that one day the sun might freeze and the the earth grow cold or the sun explode in a terrific thermal cataclysm and burn down our house of cards? — Ray Bradbury

Earth was the winner of the ultimate lotto, with 500 million to one odds, this one planet, of comparable, size to its other 17 billion siblings, became the life force of the universe itself. But the inhabitants of earth did not just inherit life, they inherited all that life has to offer a sentient species. It offers them - as a gift - love, joy, surprise, wonder, friendship, as well as spirituality, art, literature, music, and most importantly morality. A morality that is capable of reaching beyond its species to that of other living creatures on this shared fishbowl called Earth. — Leviak B. Kelly
