A group of researchers working with the space telescope “Hubble” discovered the most distant star is not a supernova known to date. The Orb is located at a distance of about 9 billion light-years from Earth and hundreds of thousands of times greater than the brightness of the Sun.
The star was the official designation of MACS J1149 Lensed Star 1 (LS1), and the name Icarus in honor of the popular character in Greek mythology. Its light reaching the Earth earth now began its journey when the universe was younger than about three times since the Big Bang a little more than four and a half billion years before the Solar system was still about the same amount of time.
Although the star refers to the blue supergiants, i.e. it is very large, the opportunity to see her was for the scientists to be a great success — usually at a great distance from Earth, scientists can only distinguish light of entire galaxies together or supernova. Known to date “normal” single stars are placed, at least a hundred times closer to the Earth. The new discovery helped to make the effect of gravitational lensing — galaxy cluster MACS J1149+2223, located at a distance of about five billion light-years from Earth, caught between Land and the open star, on the orders of amplifying its light. Thanks Ikar was able to detect with a telescope.
Scientists hope that Icarus will allow you to answer many questions about the evolution of blue giants and other bright stars. Moreover, according to the researchers, it is no exaggeration to assume that the opening marks the transition of astronomy into a new phase of exploring remote single stars.
The study was published in the scientific journal Nature Astronomy.
Recently, studying a young star RZ Piscium in the constellation Pisces, the experts at the American space Agency NASA came to the conclusion that she destroyed several planets and absorbs remaining from which clouds of dust and gas.
