Debra Fischer Quotes

What we expect to find, certainly in our own solar system, are probably simple single or multiple-cell forms of life. To get to intelligent life takes stability of conditions over huge, long periods of time.

We're going to understand that there is life on other bodies in the solar system.

Water-based life is very much an Earth-centric view, and we can push the envelope on that here in our own solar system. We have the methane seas of Titan.

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

Theoretically, there are planets with an environment that can support life. As yet there is no evidence that there indeed is life on other planets. It's only a matter of time before we get to know.

People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.

Life outside of Earth is probably going to be really hard to find.

I think Pluto has to be considered among the places in the solar system that are possible homes for life.

As far as I'm concerned, Enceladus has become the go-to place in our solar system for issues bearing on extraterrestrial life. It's a great place to examine extraterrestrial organic chemistry that is water-based and, therefore, like biotic chemistry on Earth.

Astrobiology is the science of life in the universe. It's an attempt to scientifically deal with the question of whether or not we're alone in the universe, looking at the past of life, the present of life, and the future of life. It's an interdisciplinary study incorporating astronomy, biology, and the Earth sciences.

Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.

I am absolutely certain that life can exist in outer space, move around, find a new aqueous environment.

I think there must be some other life forms, even if they're microscopic.

The overwhelming bulk of the cosmos is deathly quiet. But here and there - on worlds where matter is thick and conditions are right - noises are commonplace. And in some cases, these noisy worlds may ring with the sounds of life - the bleats and bellows of creatures we have never seen, but may someday discover.

There's life all over this universe, but the only life in the solar system is on earth, and in the whole universe we are the only men.

Once we become a multiplanet species, our chances to live long and prosper will take a huge leap skyward.

If few worlds have microbial life, it dramatically reduces the chances that more complex organisms exist.

Among the plausible niches for extraterrestrial life in our solar system, the clouds of Venus are among the most accessible and the least well explained.

We don't know how many planets we're going to have to examine before we find life, and not finding it on 10 or 100 doesn't mean it's not there. This may be very tricky.

Where there's water on Earth, you find life as we know it. So if you find water somewhere else, it becomes a remarkable draw to look closer to see if life of any kind is there, even if it's bacterial, which would be extraordinary for the field of biology.

Perhaps, as some wit remarked, the best proof that there is Intelligent Life in Outer Space is the fact it hasn't come here. Well, it can't hide forever - one day we will overhear it.

I believe that there may be intelligent life on other planets.

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.

No astrophysicist would deny the possibility of life. I think we're not creative enough to imagine what life would be like on another planet. Show me a dead alien. Better yet, show me a live one!

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.
