The most pristine star yet found in the known universe

Interesting, ta.

>Deeper analysis of the Magellan spectra showed that it has less than 0.005% of the sun’s metal content. It is twice as metal-poor as the previous record holder for most-pristine star and has particularly low abundances of iron and carbon. In fact, it is 40 times more metal-poor than the most iron-poor known star.

By incorporating data from the European Space Agency’s Gaia mission, the students were also able to determine that SDSS J0715-7334—which exists about 80,000 light-years from Earth—was born elsewhere and got pulled into our Milky Way galaxy over time.
