earthlike exoplanets part 2

Are there extrasolar planets beyond our solar system ? This was once a question that had seemed very far fetched to most scientists that there would be planets out of our solar system and even if there were extrasolar planets out there how the hell would we be able to find them seeing that they barely emit ant light at all ?
Approximately 50 lights years away from Earth in the constellation Pegasus is a gas giant exoplanet. Just about the same size as Jupiter and it orbits its parent star about once every four days. This planet is known as a hot Jupiter and the exoplanets name 51 Pegasi B, the first extrasolar planet to be detected orbiting a star out of our solar system. This discovery was a break though but really jsut a stepping stone to finding a exoplanet similar to our very own Earth. Even by chance if there is just 1% of the stars out there have a earthlike planet in there solar system that still leaves the number of earthlike exoplanets over a billion. So if we can find just one earthlike world then we will definitly know that they are very common. And if earthlike planets are common then guess what else is? Life and that is our ultimate goal. We are getting closer to finding earthlike planets like Gliese 436B. Which was found to have a density of 2.2 grams per cubic centimeter. Which means that this planet is mostly made of rock and water. But unlike earth this planet is completely covered with water but it is very different from our Earths water, the water is basically solid from so much pressure just like ice except it is not cold. So still not very earthlike but this is one of the smaller extrasolar planets we have discovered yet.
A good place to start looking for earthlike planets would be around smaller stars or dwarf stars, like Gliese 876, which we have found three exoplanets orbiting around it two are like jupiter and the other one Gliese 876D has a mass of just about 5 times that of Earth. All three of these planets are thought to be orbiting in a "habitable" zone and the smaller extrasolar planet may even have liquid water on it. The Gas Giants inside the stars habitable zone surely wont be a good place for water and life but it is almost certain that these gas giants have many many moons which may be full of life. Just 15 light years away will we be able to ever get a good look at these exoplanets ? Yes. AS soon as the Giant Magellan Super Telescope is complete we will be able to view Extrasolar Planets.
