Newly spotted red giant could be one of the oldest stars in the universe

The video discusses the discovery of a red giant star located 500 light years from Earth, which may be one of the oldest stars in the cosmos. According to a study published in the Monthly Notices of the Royal Astronomical Society, this red giant is likely a descendant of the first stars created by the Big Bang, which are believed to be extinct. The red giant has the lowest iron content ever detected, suggesting it is much older than metallic stars. The first stars were composed of hydrogen and helium, and their supernova explosions created metal elements. This explains why the red dwarf, a progeny of the first stars, contains minimal iron.
