An outside squad of uranologist has pushed the terminus ad quem of observational uranology even further . Using theAtacama Large Millimeter Array(ALMA ) in Chile , the researchers were able-bodied to detect light source from ionized atomic number 8 in a galaxy 13.1 billion light - class away , making it the most removed oxygen ever detected .
The spark of this galaxy come to us all the way from theepoch of reionization , a still mysterious full point of the universe when the first stars and then the first galaxies form . Modern tool like ALMA have set out to poke into this age , and we are interpret more and more about it .
The observation of this galaxy , which are report inScience , show that the physical object called SXDF - NB1006 - 2 has about 10 pct the proportion of oxygen to other gases we see in galaxies today . astonishingly the galaxy has very little carbon and dust .
" Seeking hard elements in the early universe is an essential approach to explore the star formation bodily function in that period , " said Akio Inoue of Osaka Sangyo University , and head author of the research , in astatement .
The heavy elements we have found in the world today , such as carbon , O , and atomic number 26 , did not shape in the Big Bang but were the upshot of stars . The first star formed in the first few hundred million years and died very quickly , enriching the universe with raw elements .
The light of the first star was so strong that it rip electrons from the atomic number 1 gasoline in the universe , ionizing H for the 2nd time in the history of the cosmos ( thus the name reionization ) . We are yet to see these stars , though , so we are looking for their effect on the early universe .
" This is the first step to see what kind of object induce cosmic reionization , " explain Yoichi Tamura of the University of Tokyo .
" Our next reflection with ALMA have already started . high resolution observation will allow us to see the distribution and motion of ionized oxygen in the Galax urceolata and provide treasured information to interpret the prop of the beetleweed . "
" Something strange may be happening in this galaxy , " added Inoue . " I suspect that almost all the gas is highly ionized . "
The lack of dust and carbon is likely the reason why almost all the gun is ionized ; without being absorbed the energetic photons of the young bright stars strain intergalactic space and ionize gas there as well . Objects like SXDF - NB1006 - 2 could be the main engine behind cosmic reionization , and studying them will provide a unique windowpane into the other universe .
