Quotes About Habitability

The moon's closeness is a huge advantage: To make it habitable, we would first have to bombard it with water-ice comets, a tricky endeavor best attempted with the many resources waiting on and near Earth.
~ Gregory Benford
furniture n. habitability improvements (U.S. Navy) The U.S. Navy paid $31,672 for a couch, 20 dining room chairs, and a loveseat for the destroyer USS Kidd. The furniture was called "habitability improvements.
~ William D. Lutz
Data from orbiting telescopes like NASA's Kepler Mission hint that the tally of habitable planets in our galaxy is many billion. If E.T.'s not out there, then Earth is more than merely special - it's some sort of miracle.
~ Seth Shostak
As chief scientist, it's sort of my job to look at bridges between what we do and to see the connections. But when we try to understand how are planets around other stars habitable... to looking back at the Earth - how are the changes that are taking place, how are they going to affect humanity?
~ Ellen Stofan
Habitability is the characteristic of source code that enables programmers, coders, bug-fixers, and people coming to the code later in its life to understand its construction and intentions and to change it comfortably and confidently.
~ Richard P. Gabriel
NASA, and all the other spacefaring nations of the world, have agreed to a set of 'planetary-protection' principles, aimed at preventing the accidental contamination of another habitable world with organisms from Earth.
~ David Grinspoon
Man, n. An animal so lost in rapturous contemplation of what he thinks he is as to overlook what he indubitably out to be. His chief occupation is the extermination of other animals and his own species, which, however, multiplies with such insistent rapidity as to infest the whole habitable earth and Canada.
~ Ambrose Bierce
It is those who have compassion for all life who will best safeguard the life of man. Those who become aroused only when man is endangered become aroused too late. We cannot make the world uninhabitable for other forms of life and have it habitable for ourselves. It is the conservationist who is concerned with the welfare of all the land and life of the country, who, in the end, will do most to maintain the world as a fit place for human existence.
~ Edwin Way Teale
It had been impressed on Rien all through her childhood how fragile the habitable sphere was, and how much functionality had been lost through accident, negligence, malice, and the simple gnawing of entropy.
~ Elizabeth Bear
My perspective is the Earth will be here. It just may not be habitable to our life form. We get confused. We think we're the center of everything.
~ Mae Jemison
The usual metric for whether a planet is habitable or not is to ascertain whether liquid water could exist on its surface. Most worlds will either be too cold, too hot or of a type (like Jupiter) that may have no solid surface and be swaddled in noxious gases.
~ Seth Shostak
Here on Earth, we've found organisms that thrive in environmental conditions we would have once thought uninhabitable. The presence of these extremophiles suggests that life could potentially take hold on worlds other than our own.
~ Nick Sagan
Give consideration to the fact that alien astronomers could have scrutinized Earth for more than 4 billion years without detecting any radio signals, despite the fact that our world is the poster child for habitability.
~ Seth Shostak
Bruno believed that the universe is infinite and filled with an infinite number of habitable worlds. He also believed that although each world exists for a brief moment when compared to the life of the universe, space itself is neither created nor destroyed; the universe is eternal.
~ Brian Cox
Life is rich, always changing, always challenging, and we architects have the task of transmitting into wood, concrete, glass and steel, of transforming human aspirations into habitable and meaningful space.
~ Arthur Erickson
Had Earth been much closer to the Sun, the oceans would have evaporated. Had Earth been much farther away, the oceans would have frozen.
~ Neil deGrasse Tyson
Had Earth been much closer to the Sun, the oceans would have evaporated. Had Earth been much farther away, the oceans would have frozen. In either case, life as we know it would not have evolved.
~ Neil deGrasse Tyson
To All the World: I declare the earth is hollow and habitable within; containing a number of solid, concentric spheres; one within the other, and that it is open at the poles twelve or sixteen degrees. —J. Cleves Symmes of Ohio, late Captain of Infantry, April 10, 1818; quoted in Sprague de Camp and Ley, Lands Beyond, New York, Rinehart, 1952, x
~ Umberto Eco
Iceland, though it lies so far to the north that it is partly within the Arctic Circle, is, like Norway, Scotland, and Ireland, affected by the Gulf Stream, so that considerable portions of it are quite habitable.
~ Harry Johnston
Planets that don't currently sport plate tectonics, such as Venus and Mars, are scarcely habitable. Tectonics might be a requirement of any world that aspires to a rich diversity of life.
~ Seth Shostak
I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.
~ David Grinspoon
God is dead,' Nick said. 'They found his carcass in 2019. Floating in space near Alpha.' 'They found the remains of an organism advanced several thousand times over what we are,' Charley said. 'And evidently could create habitable worlds and populate them with living organisms, derived from itself. But that doesn't prove it was God.
~ Philip K. Dick
No other planet in the solar system is a suitable home for human beings; it's this world or nothing. That's a very powerful perception.
~ Carl Sagan
There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history.
~ John D. Barrow
