Could there be life sustaining planets wihtin our own galaxy?

Answer 1

You're on one.

Yes.

Answer 2

This is the big question, you'll need to take a look at the famous Drake equation. It goes a little something like this.

The Drake equation states that:

N = R* × fp × ne × fl × fi × fc × L

where:

N is the number of civilizations in our galaxy, with which we might hope to be able to communicate;

and

R* is the rate of star formation in our galaxy
fp is the fraction of those stars that have planets
ne is the average number of planets that can potentially support life per star that has planets
fl is the fraction of the above that actually go on to develop life at some point
fi is the fraction of the above that actually go on to develop intelligent life
fc is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L is the length of time such civilizations release detectable signals into space.

This equation does not only help us figure out if there is life in the milky way galaxy but weather of not there is intelligent life int he milky way galaxy.

The only problem with the equation is that we do not know all the values of the formula. As scientists discover more and more planets around nearby stars we an expand that to the rest of the milky way and get a better idea of what the real answer is.

Answer 3

If you are refering to planets that could sustain any type of life, surely there is. Among the billions of stars in the milky way, there must be at least thousands that could sustain some type of life.

If you are refering to planets similar to Earth, with similar gravitational field, oxygen/nitrogen atmosphere, containing water, approximately 1 AU from a sun-type star where the atmospheric pressureand temperature is tolerable and harmful radiation is blocked out, that could sustain terrestrial life, the odds are less, but still possible.

Answer 4

There are around 200 Billion stars in our galaxy... if a fraction of them have planets around them, and of those a fraction have terrestrial planets (or moons) around them, then the possible number of "M" class planets (to borrow a term from Star Trek) is still amazingly high. Whether any of those actually have life or not is a matter for speculation, as it is unlikely that we (humans) will ever be able to visit them.

Answer 5

There could, insofar as we have been unable to investigate more than a miniscule fraction of the stars and potential planetary systems in this galaxy. Without more information, we can't say if there are or there aren't. Certainly there is no physical reason why not.

Answer 6

It would seem to me that the posibility of no life would be so great, it would be an endless number to one. The Drake formula(look it up) states that with billions of stars in our own galaxy alone there would have to be millions of possible planets with life. Now with an endless universe, with billions of galaxies. well, do the math, has to be life out there, but it don`t have to be as we know it.

Answer 7

Yes. It's actually a good chance that there is. I'm not saying there is a good chance that there is life on one of those planets, but it may develop or we can move there after we use up all of Earth's resources (Lol).

Answer 8

There is absolutely no intelligent life in the entire universe.

Answer 9

More than likely.

Answer 10

yes totally remeber we are one solar system there prbably is more life out there
