NASA and the European Space Agency to explore new stars in 2015
A group of Australian astronomers pinpointed a sector of the Milky Way where life probably exists. This is unfortunately a remote area which will not be reached by men in the nearest time.
There are four components that are required for life to begin: a "feeding" star (the Sun for our planet), enough heavy elements (carbon, oxygen and hydrogen) for a planet to form, enough time for adequate evolution (at least 4 billion years) and no super-new stars in close vicinity that could cause an explosion and death to everything living around.
As based on the four components and employing a program developed by student astrophysicist Yeshe Fenner, scientist Charles Lineweaver and his colleague Brad Gibson have managed to calculate the so-called "inhabited galaxy zone". The scientists say that the Solar system belongs to the "inhabited zone", but it is too young and too remote from the center of the galaxy to have adequate development of life.
Professor Gibson says that similar researches were held several years ago when scientists wanted to find out if life existed on Mars. This time, the scientists have developed a similar program for the entire of the galaxy.
None of the stars mentioned in the research of the Australian scientists has ever been thoroughly studied. NASA and the European Space Agency are to launch a new space device in 2015 to explore the stars.
