Berlin, 16 mar ( EFE).-the Hubble Space Telescope has managed to capture the image more detailed and sharp until the time of Messier 9, a globular cluster of stars located near the center of our Galaxy, said today the European Space Agency (ESA) from their central German of Garching, to the South of the country.
Barely perceptible to the human eye, the Hubble space telescope can be seen more than 250,000 stars in this cluster, approximately 25,000 light years from Earth, near the center of the milky way and such proximity that the Galactic Center gravitational forces deform it slightly.
It is estimated that the globular clusters contain some of the oldest stars in our Galaxy, born when the universe had no more than a small fraction of its present age.
The stars of Messier 9, as well as double the age of the Sun, have a markedly different composition and are enriched with significantly less heavy than the Sun elements.
In particular, the crucial elements for life on Earth, such as oxygen and carbon, as well as the iron that makes up the Earth’s crust, are particularly scarce in Messier 9 and in such clusters.
This is due to the heavier elements in the universe were formed gradually in the center of the stars and the explosion of the supernova.
During the formation of the stars of Messier 9 fewer of those elements existed with difference.
In addition to showing the stars individually, the image of the Hubble allows to clearly see the different colors of the stars, which are directly related to its temperature.
Well, against what could be expected, as more red more cold and blue the more hottest.
The broad spectrum of stellar temperatures is here clearly deployed due to the huge palette of colors visible in the image of Messier 9 captured by the Hubble.
The environment of Messier 9 is equally interesting and consists of two nebulae extensive and dark known as Bernard 259, South-East of the globular cluster, and Bernard 64, to the West, clearly visible in the panoramic image of the telescope. EFE
