00:03the universe is old around 13.8 billion years old to be exact but while many cosmic objects
00:09like stars come and go they can live for a long time and now researchers believe they have just
00:14discovered one of the oldest living stars in the universe its technical name is s plus j210428.01
00:22dash 004934.2 and it's 16 000 light years away so how do astronomers from the national science
00:29foundation know it's so old experts analyzed the chemical makeup using cosmic spectrometers
00:34finding that it contained elements produced only from first generation stars but also it's extremely
00:39low in later generation materials like carbon iron oxygen magnesium and lithium as early universe
00:45composition was less stars and planets and more clouds of helium and hydrogen this discovery not
00:50only means this is the first second generation star we've ever identified but it could also point us in
00:55the direction of even older stars perhaps even ones that were created in the first moments of the
01:00universe
