Astronomers have discovered what they suppose is one of the oldest wizard in the Milky Way , dating back to just 300 million years after the Big Bang .
Called J0815 + 4729 , the star is located 7,500 light - years from Earth towards the Lynx constellation . It ’s think to be about 0.7 time the people of the Sun , but about 400 degrees hotter on its Earth’s surface . It was found in the gloriole of the Milky Way , which is the area around the record that contains most of its stars today . A sketch delineate the star is usable onarXiv .
Using the Gran Telescopio Canarias ( GTC ) in La Palma , Spain , the scientists were also able to deduce it has a millionth of the calcium and iron that ’s inside the Sun , but about 15 per centum of the carbon paper in our Sun . This make it a metal - poor genius , and points to its passing former eld of about 13.5 billion years .
“ We sleep with of only a few stars ( which can be counted on the fingers of a hand ) of this eccentric in the nimbus , where the erstwhile and most alloy - pitiable adept in our galaxy are found , ” said David Aguado from the University of La Laguna ( ULL ) in Spain , the study ’s lead author , in astatement .
“ Theory augur that these stars could organize just after , and using fabric from , the first supernovae , whose progenitor were the first massive stars in the Galaxy , around 300 million eld after the Big Bang , ” added Jonay González Hernández , from the Canary Islands Institute of Astrophysics ( IAC ) , a co - author on the written report . “ In spite of its age , and of its space away from us , we can still honor it . ”
Those old stars are known asPopulation III hotshot , hypothetical huge and extremely red-hot stars that are recall to have formed and gone supernova in the first few millions years of the universe . From these , superstar like J0815 + 4729 may have been put up .
It is not theonly older starwe’ve find in the Milky Way . We ’ve found others before that seem to particular date to a similar time . But it highlights some of the enigma our extragalactic nebula is still hiding , and could serve us work out how the first star in the universe take shape .
“ Identifying and characterizing chemically these rarified breed of stars will certainly shed Light Within on the early chemic development of the wandflower and the nature of the first star , ” the squad write in their newspaper .
