There is the extreme of hopelessness and the inevitability of doom, a deep despair that comes from the sense that our industrial, consuming society is jeopardizing the planet.
We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
I'd like to jump a couple hundred years into the future and work with the scientists who are getting back the first information from our probes to planets orbiting nearby stars.
Let's be clear. The planet is not in jeopardy. We are in jeopardy. We haven't got the power to destroy the planet - or to save it. But we might have the power to save ourselves.
I do hope there are other wonderful planets living and thriving out there, but ours is special because it is ours and ours to take care of. We really can't take that too lightly.

The discovery and investigation of life on other planets is likely to change many of our ideas about how life arose on the Earth and even what is life and its natural development.
It can be very hard to know the history of a particular star, but once in a while, we get lucky and find stars with chemical compositions that likely came from in-falling planets.
We treat a planet at crisis point as an externality that can be shunted into a future generation. We continue to act as if we had the natural resources of several planets, not one.
I just keep trying to explain what's going on with our planet - and now, to explain what's going on with our politics, which explains why we're not doing anything about the former.
I decided five years ago that I wanted to truly understand, for myself, what the state of the planet was, and when I dug into it, what I found was quite different than I'd imagined.
I'm really fascinated with anything that takes place between the 1920s up through the 1960s. In some ways it feels familiar, and in other ways it feels like it's from another planet.
Go to a place and just send out emails. That's my entire life. I go to countries and I ask, "Who would I know who lives here?" Not even do I know, but who exists and is on the planet.
The universe has told us the most common types of planets are small planets, and our study shows these are exactly the ones that are most likely to be orbiting Alpha Centauri A and B.
Man is a microcosm, or a little world, because he is an extract from all the stars and planets of the whole firmament, from the earth and the elements; and so he is their quintessence.
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.
For a long time, we've worked on detecting planets with whatever was at hand, making use of existing small telescopes or even amateur telescopes. It's time to move on to the next stage.
Earth is going to lose its oceans in the future, just as Venus did in the past. How long planets retain their oceans is a function of distance from the sun, all other things being equal.
I simply haven't the nerve to imagine a being, a force, a cause which keeps the planets revolving in their orbits and then suddenly stops in order to give me a bicycle with three speeds.
I would like to see an agreement that recognizes that we live on the same planet and that some interests, such as human rights, must be universal and that all religions must be respected.

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.

It is astonishing to realise that the human species survived hundreds of thousands of years, more than 99 percent of its time on this planet, with a life expectancy of only eighteen years.
I would like to see us get this place right first before we have the arrogance to put significantly flawed civilizations out onto other planets, even though they may be utterly uninhabited.
Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.
Why would you envy a man who doesn't know the names of all the planets, is a 'high functioning' sociopath, and has no friends? Because Sherlock Holmes thinks in all the ways we wish we could.
We are the laws of chemistry and physics as they have played out here on Earth, and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets.
Planets are the big bullies of the planetary system that are, that basically ignore everybody else around them. And everybody else has to deal with the planets. Those are what the planets are.

The day is not far off when we will be able to send a robotically controlled genome-sequencing unit in a probe to other planets to read the DNA sequence of any alien microbe life that may be there.
It's in every person's life, around 27 to 29 years old, the stars and the planets align themselves to exactly the way they were when you were born. You're faced with yourself. There's no running away.
