An international group of researchers working with optical telescope Very Large Telescope and the ALMA radio telescope was able to calculate the distance to the galaxy MACS 1149-JD in the constellation Leo. As it turned out, this distance is 13.2 billion light years, making the galaxy the most distant object, the distance to which the date is known. A more interesting discovery was the fact that MACS1149-JD1, according to experts, contains a lot of oxygen.
Galaxy MACS 1149-JD – has a Cosmological (metagalactic) red shift with an index of 9.2
According to experts, the existence of this galaxy has been known since 2012 and it was initially studied with telescopes “Hubble” and “Spitzer”. However, to know the exact distance to MACS1149-JD1 galaxy and find out that it is possible to see the most distant from Earth, the oxygen was only now. It is worth noting that the age of the Universe is estimated at 13.81 billion years, scientists see the galaxy MACS1149-JD1 as it was when the known world was much younger.
Traces of oxygen in a distant galaxy, according to scientists, will help to answer many of the questions facing today’s astrophysics. In particular, the new data will be useful in order to clarify the early Universe when the first stars and when their bowels started to appear “heavy” elements (astronomers refer to this category all chemical elements except hydrogen and helium). Experts suggest that the first stars in the galaxy MACS1149-JD1 was formed approximately 240 million years after the Big Bang and it is likely that these stars were among the first in the world.
Experts hope to obtain even more information after about a year will start to work the new orbital telescope “James Webb”.
On the results obtained, scientists reported in the journal Nature.
Recently on the surface of the International space station was discovered holmium — substance, nearly no Strachowice on Earth, but is present in large quantities on the Przybylski star in the constellation of Centaurus.
