Astronomers Discover Ancient Star Formed by Big Bang

Sydney: A team of astronomers has found what could be one of the universe’s oldest stars, almost entirely made of materials formed by the Big Bang. Residing in the same part of the Milky Way galaxy as our own solar system, the star is believed to be up to 13.5 billion years old which is evidenced by its extremely low metal content, or metallicity, Xinhua news agency reported. Up until around 1990, scientists believed that only massive stars could have formed in the early stages of the universe, and could never be observed because they burn through their fuel so quickly and die. However, the new study has shown that it is possible for low mass stars to last as long as the 13 billion years since the Big Bang — Red Dwarf stars for instance, which have a fraction of the mass of the sun, are thought to live for trillions of years.
