Astronomers have recently identified a new type of star known as a “metal-poor” star, which is believed to be the oldest stars in the Milky Way. These stars are incredibly rare, with only a handful of them ever being discovered since their discovery in the 1990s. Now, a team of astronomers have identified a new candidate metal-poor star, located in the Ursa Major constellation. This star is estimated to be around 13 billion years old, making it one of the oldest stars ever discovered. Its composition is incredibly unique, with a metallicity that is more than a thousand times lower than our sun. This could help us to understand more about the early formation of our own galaxy, as well as other galaxies in the universe. This discovery is sure to open up a new world of possibilities for astronomers and astrophysicists alike.
