Scientists have uncovered the origins of one of the Milky Way's oldest stars, which was first discovered in 2018.
The origins of one of the Milky Way’s oldest stars was discovered by inspecting and observing the object using the ESPRESSO spectrograph, an instrument that the international team of researchers relied on heavily during their observations. The ESPRESSO instrument provides high-precision data, which revealed small variations in the object’s velocity.
The researchers also found that the Milky Way’s oldest stars had not changed much since their primordial composition, and instead, they act as a pristine sample of the medium that they formed millions of years ago. The project to determine this has relied on nearly ten years of research and observations.
The researchers say that it can give us a better chance at understanding the overall chemical evolution of our universe, which has seen some changes since the Milky Way’s oldest stars formed within the galaxy. It’s also intriguing because this study comes on the heels of scientists discovering the
