Galaxies like the Milky Way, may not be the best, "the cradle of life" in our Universe - in giant galaxies poor "newborn" stars and at least two times more massive than the Milky Way, may be 10,000 times more habitable planets than in our galaxy, according to new research. In this research work, astronomers studied more than 140,000 galaxies closest to us in an attempt to answer the question: what type of galaxy is best suited for habitable planets? To their surprise, the scientists concluded that the large spiral galaxy similar to our own galaxy, are not the most suitable for habitable planets, galaxies of the Universe as explained study co-author Anupam Mazumdar, cosmologist particles from Lancaster University, UK, in an interview online edition Space.com. Scientists have studied the galaxies observed with the help of Apache Point Observatory, USA, is part of the Sloan Digital Sky Survey. The study found that the most suitable for habitable planets type galaxy is rich in "metals" (elements heavier than helium) galaxy whose mass is not less than twice the mass of the Milky Way, and the rate of star formation is more than ten times lower than that of our Galaxy A total of 140,000 galaxies acting as the objects of the study, 200 galaxies, best meet the developed criteria, have been recognized by researchers as the standard of "habitable" galaxies. The nearest galaxy to us in this group, which bears the name of the Maffei 1, located 9.5 million light-years from the Milky Way.
