Could there possibly be life on another planet?

Answer 1

There are approx 5x1022 stars in the Universe. (see a previous Wiki question)

Say only 1 in a million has a planetary system.

Say only 1 in a million of these has a planet capable of supporting life.

There are therefore approx 5x1022 / 1012 = 5x1010 'earth like' planets.

Suppose only 1 in a million of these actually evolved intelligent life.

There are at least 1010 / 106 = 10,000 intelligent races out there!!

At least one individual from one of these (apart from me) is probably sitting at their computer working out this very fact.

_______________________

As appealing as it is to imagine that there are thousands of earth-like planets, there is not yet any evidence that any exist outside of earth itself. The numbers are compelling, but they are not proof. Rather than getting caught up in the wildly exciting prospect of finding planets that harbor forms of life that we would recognize as such, it is more important right now for us to continue refining our abilities to accurately detect smaller and smaller planets that have even a chance of being earth-like.

The answer is unknown.

Scientists have been puzzling over that question for years and they still haven't found an answer.

Humans are only able to land on a few planets due to the time it takes to travel so cannot fully explore each planet.

ANOTHER ANSWER: By the way it would be very egotistical of us to think that we are the only life in the universe .... (that would be a lot of wasted space if we were!)

Answer 2

Sorry but the current research has not proved anything in that line. So that means we only know of life on planet Earth as for now.

But we have only begun to search, and several Jupiter-like planets have been discovered orbiting reasonably close suns. As our technology improves, we will be able to detect more planets, and we will be able to detect smaller planets. We don't yet know whether or not other planets harbor life as we know it, but there is nothing that rules it out.

There are many other planets in the universe but not to support life that we have discovered but in such a big universe there probably are many planets similar to ours and capable of supporting life. Whether or not we will ever be capable of discovering any of them is another matter.

Answer 3

We have not much of a chance, though a star nearby called Vega has a doughnut shaped cloud around it, and we're hoping that cloud becomes lumpy, and the lumps become clumps and the clumps become chunks and the chunks become rocks and that all ends up as planets. And if we find a planet with a similar distance from a star around the same heat as our sun, well, there's a 60% chance of finding life on that planet. so yeah Vega could have planets if that cloud becomes lumpy, and if Vega gets planets the formation of planets will take a few million years and then the sun will be dying, and not much chance of getting to that other planet with life (if there is any) in time to survive.

Answer 4

Yes, they have found a planet quite recently that has the same kind of climate as Earth and consequently scientists and astronomers think there is life on the planet.

Edit: I try to keep up-to-date on this question. I must say this answer is news to me. Are you sure? I heard that "Kepler" found a planet in the

"habitable zone", but that's not quite the same thing.

Answer 5

In view of the discovery of liquid water in several place in the solar system the existence of primitive forms of life is likely, but the chances of anything as complex as a bacterium are small.

Answer 6

Absolutely, at least in bacterial form.
