Astronomers claim to have found the oldest star yet discovered – a 13.5-billion-year-old sun hovering on the edges of our Milky Way, according to a new study.
The star may sound unremarkable, 2MASS J18082002-5104378 B, but its contents are pretty special. It’s classified as an ultra metal-poor star (UMP) and is “the most metal-poor thin disk star system by a considerable margin,” according to researchers from John Hopkins University, Carnegie Observatories, United States and Monash University, Australia.
