Can reach the reconstruction of some people to about 90 years, while the Ages some if over the age of fifty years, and according to our experience became possible to know the reasons why people are aging before others and perhaps, according to their lifestyle, and the amount of effort and energy they are making in their lives Feachekhoun early or long young people have.
Recently, he became able to astronomers predict the age of "clusters stellar" star clusters and stars in our galaxy, "Milky Way" based on this technique almost, so depending on the study, conducted on clusters astrocytes by Space Telescope U.S. European "Hubble" Hubble Space Telescope.
Spherical stellar clusters Globular clusters is a large group of stars take spherical shape spherical and cohere with each other by gravity, stellar clusters arose in the early stages of the age of the universe where build it ranges between 12-13 billion a year, noting that "major blow" Big Bang or as it is also called "big bang" a moment of emergence of the universe was before about 13.7 billion years, and there are in our galaxy "Milky Way" is about 150 spherically stellar clusters consisting of big stars age.
But a recent study conducted by a team of astronomers who used the space telescope "Hubble" and Telescope "ISO" ISO with a diameter 2.2 meters in the area "to Wasilla" La Silla is located on the heights of Chile in South America have shown that it is not necessarily the presence of big stars Age in this globular clusters of stars, where it was noted the presence of star young and middle-aged belong to this stellar clusters, has published the results of this research during a scientific paper in the journal "Nature" Nature in its issue on December 20, 2012 year.
Chairman of the Scientific researcher, "Francisco Veareraaro" Francesco Ferraro from the University of "Bologna" University of Bologna said that we uncovered the presence of star blue young and hot in these clusters, and asked the team about the reasons that make the stars aging before the other, where studies indicate the primary that some stars evolve very quickly and rapidly aging seems an elderly relative to those of the stars, and we worked to develop a method for measuring the rate of aging.
Formed stars in the clusters stellar career during a relatively short time, and the old tight also because it is formed in the same period as well, and the age of the shining stars be short also because they consume energy quickly due to heat high and shining intense, and then transformed into clusters of spherical great age, But the strange thing is that there are some stars are still young, as if it did not consume energy implemented.
Explains scientists and a blue stars young clusters stellar career-star big Age that some of the stars withdraw their energy from a nearby star or star facilities, long life and looked like a newborn and appear blue in color, or as it is called by some astronomers, "Blue Stars extremist" blue stragglers and interpretation The other is that some stars collided with the other stars in the cluster Vantage for this collision Nujoma newborn with the first stars was a great age.
Concentrated star heavy in the center of the cluster stellar because of the significant weight, a process similar to a phenomenon called "sedimentation" Sedimentation, a process which is the transmission of particulate solids deposition in another place, and "Blue Stars extremist" is responsible for the occurrence of this process, as the gloss These stars facilitates the process of monitoring of astronomical Mrasdna.
In order to understand the scientists how aging stars in the clusters are spherical better, drew a map that identifies the location 21, a star of Blue Stars extremist in clusters, spherical, according to what was seen through the space telescope "Hubble" and Telescope "ISO" in Wasilla in Chile, where the pictures showed Place of twenty stellar clusters spherically high resolution.
After analysis of astronomical observations, astronomers found that a few star clusters spherical young and middle-aged and most of their stars from extreme blue stars, while most large spherical stellar clusters age, and blue stars are concentrated in the center of this extremist clusters because of the high mass.
Vice-Chairman of the Scientific researcher "Barbara Lanzoni" Barbara Lanzoni from the University of "Napoli" Italian University of Bologna said that in the case of clusters "fast aging" fast-aging believe that the process of "deposition" will be completed within a few hundreds of millions of years, but For the slowest process, it takes several times for the current age of the universe, and the heavy concentration of stars at the center of the cluster, cluster in the end exposed to a process called "major meltdown" core collapse, where stationed a large mass of stellar material in the center of the star cluster.
