A Quote by Sandra Faber

It's quite likely that planets and solar systems like ours could be forming in other galaxies in great numbers.

When I was a little kid, we only knew about our nine planets. Since then, we've downgraded Pluto but have discovered that other solar systems and stars are common. So life is probably quite prevalent.

Buzz Aldrin

Because of Hubble and other telescopes, we've now discovered that there are probably planets around every star, or virtually every star. There are solar systems around most stars. And the fact that we're here on a planet, Earth, means that it's likely there's lots of other Earths out there.

John M. Grunsfeld

There must be enormous numbers of planets around the stars in the many galaxies in our observable universe. We may be sure that wonderful things are happening on these planets that the human race never will observe.

Jim Peebles

The universe for me was other planets and other star systems and other galaxies. I enjoyed tracking it, but it had no specific influence on my ambitions for that reason. It wasn't really far enough away from Earth to matter to me.

Neil deGrasse Tyson

When authoritative reports of radical-design craft having spectacular performance are viewed in the light of a stream of astrobiological discoveries, the possibility that some UFOs are alien does not seem quite so farfetched. Serious-minded scientists in astronomy and other disciplines estimate there could be billions of planets in the universe, and millions that could harbor life. If even a few of those planets were occupied by technological civilizations, their ability (if not desire) to explore other worlds, such as ours, must be a possibility.

Don Berliner

Outside intelligences, exploring the Solar System with true impartiality, would be quite likely to enter the Sun in their records thus: Star X, spectral class G0, 4 planets plus debris.

Isaac

There's no doubt that the search for planets is motivated by the search for life. Humans are interested in whether or not life evolves on other planets. We'd especially like to find communicating, technological life, and we look around our own solar system, and we see that of all the planets, there's only one that's inhabited.

Debra Fischer

Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.

Seth Shostak

Every field of astrophysics - whether it's our local neighborhood of planets, nearby stars and their attendant planets, galaxies, clusters of galaxies, out to the edge of the universe - every field has questions that are awaiting the power of Hubble.

Heidi Hammel

When I grew up as a kid, we didn't know there were any other planets outside of our own solar system. It was widely speculated that planet formation was an incredibly rare event and that it's possible that other planets just don't exist in our galaxy, and it's just this special situation where we happen to have planets around our sun.

John M. Grunsfeld

As our sensitivity improves, we are finally seeing planets with longer orbital periods, planetary systems that look more like our solar system.

Debra Fischer

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.

Sunita Williams

Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.

David Grinspoon

When Hubble was launched, it became clear very shortly thereafter that there was a problem with the optics.The mirror was not quite the right shape. And the one program that I had really been looking forward to doing with Hubble was studying outer planets in our solar system, the planets Uranus and Neptune.

Heidi Hammel

We all live in our own world. But if you look up at the starry sky - you'll see that all the different worlds up there combine to form constellations, solar systems, galaxies.
