On the 18th of April the astronomers led by Mr. Borucki announced the location of the most similar worlds to our planet, in which there could be life without any problem. They are located in the constellation Lyra. This is not big but it is easily identifiable for its star Vega, which is the apex of the “Summer Triangle”. Another star of this constellation is Kepler-62, which is circle by five planets, Kepler-62b, c, d, e, f, with the size of 1.31, 0.54, 1.95, 1.61 and 1.41 terrestrial radios, respectively. Compared to our enormous sphere of hot gas, the Sun, this is smaller and less bright.
The two Earth-like worlds mentioned before were discovered by the Kepler project, which the NASA started in March 2009. Its aim is to hunt planets observing 150,000 stars in a region of the sky of our galaxy. These are half the size of our planet, and they probably have oceans with humidity and cloudy skies. However, this is an assumption. There is little chance of somebody knowing if life exists or not in them, we can only see it in our dreams.
It is noteworthy that the director of the Kepler project said that one of these planets, specifically the Kepler62f with 267.3 days every year, may be the ideal place for life. The system Kepler 62 is very similar to our solar system, since it also consists two planets in the habitable region, like the Earth and Mars. As it has already been mentioned, these aren’t so big as the Earth. Therefore, they aren’t replicas of this, although the astronomers soon will discover the Earth 2.0. The most important thing is that they are located in the “Goldilocks“ zone, where temperatures are suitable for liquid water, the crucial ingredient for life. Therefore, any aquatic life would be possible. However, Kepler was not designed to tell us where we can go to live, but to study the common characteristics between the Earth and them.
In my opinion, although the Kepler project has been originally created to determine the existence of Earth-like planets in or near the habitable zone only for scientific purposes, it can be very useful. I believe that people are destroying the Earth and finishing the natural resources, so we will soon need a place with similar characteristics. In this case, the Kepler-62f is 1,200 light-years from here, so it is almost science-fiction considering going there, but with this type of projects we may find a nearest one.
