Okay now what is an Extrasolar Planet? Or briefly, a exoplanet? A exoplanet is a planet that is beyond our solar syatem orbiting some other sunlike or non sunlike star(s).
1st discovery of the exoplanet was in the early 1990's.
Since the beginning finding of a exoplanet beyond our solar system scientists have discovered guessingly 30 exoplanets from 1990 the the beginning of the millennium aka 2000.
From the start of the year 2000 until now more than 200 exoplanets have been spotted and confirmed.
The number will keep growing, day by day, and we will eventually discover another exoplanet that has all the right things to support life.
As of June 2008 there approximately 294 exoplanets confirmed.
We are strongly guessing there's about ten times the amount of exoplanets out there then stars considering we have found many stars that have definitely many exoplanets in their solar system.
I'm willing to bet that a star 5 times the size of our sun could have about 35 exoplanets orbiting it, maybe a thousand satellites, now, nearby in our milky way galaxy we are estimating theres a couple hundreds of billions of stars..

half of these stars or more is highly capable of having planets and moons orbiting it.
So the question is "does life exist beyond earth"? Most certainly just not proven YET.
Fact, there's over a hundred billion sunlike stars in our milky way galaxy, just a galaxy, normal sized, out of how many galaxies? Add another hundred billion just to be somewhat in the accurate zone...
Now how many exoplanets to you think could be orbiting out there? I am pretty sure the number doesn't exist unless you are a super math geek that knows number amounts beyond jatrizzillions? lolerz.
So is life out there on a distant exoplanet in a different galaxy? Probable.
Will we ever discover this in our life time? Not certain.
Will we discover some exoplanet that has the ingredients that could support extraterrestrial life in our milky way? With our newest technology in our lifetime we will...
but communicating with them is another fairytale..

for now...
lets just keep our eyes peeled for any new exoplanets.
