Astronomers have identified SDSS J0715-7334 as the most elementally pure star ever observed. Discovered using data from the Sloan Digital Sky Survey and telescopes in Chile, this ancient second-generation star contains less than 0.005% of the metals found in the Sun.

Evidence suggests it originated near the Large Magellanic Cloud before migrating into the Milky Way. Its composition offers a rare window into the early universe and the transition from the first stars to complex galaxies.
