A surprising fact about astronomical astronomy is that we know more about other galaxies than   our own . The Solar System is not in a great position to con all there is to know about the Milky Way . The origin of our galax is still very mysterious , but we might have found a way to learn more about it .

A team of Spanish and Italian astronomers were the first to study the globular cluster   called E 3   in detail . Globular clusters are spherical radical of star topology that tend to have formed together , so they have roughly the same age .   The squad   get wind a very erstwhile organization that formed at the very dawn of the Milky Way , with   a   chemical substance composition that is a passel rich than we expected .

The results have been published in a paper titled " Ghosts of Milky Way ’s yesteryear "   in the journalAstronomy & Astrophysics .

" This globular cluster , and a few interchangeable ones   –   such as Palomar 5 or Palomar 14   –   are ` ghosts ´ because they appear to be in the last stages of their beingness , and we say ´ from the past ´ because they are very former , "   said Carlos de la Fuente Marcos ,   one of the authors , in astatement .   " They were formed when our galaxy was virtually new - bear , 13,000 million days ago . "

" Unlike distinctive orbicular clusters , which contain hundreds of G and in some cases 1000000 of principal , the physical object canvass only has a few tens of thousands of them . "

The Sun belongs to thelatest generation of starsthat are draw as metal - robust , because a pocket-size pct of their mass is made up of ingredient heavier than hydrogen and helium . Older star run to be metal - pathetic , but the chemic opus of this globular clustering designate the headliner make 20 percent of the metallicity of the Sun . This uncovering suggests that the metal enrichment started very early in the history of the Milky Way .

This chemical theme is shared among all the stars that are members of the clustering . " This is characteristic of an aim that was created in block , in one single sequence , like what is hypothecate to have happened when our coltsfoot was born : very big star cluster ( containing million of maven ) were formed , but what remains of them today are object like E 3 , spectre from a aloof past , " say De la Fuente Marcos .

The team will proceed to study the cluster in 2016 in the Leslie Townes Hope   of answering more enquiry about the origin of this fascinating object .
