One of universe's oldest stars dating back 13.5 bn yrs found
Astronomers have detected one of the oldest stars in the universe dating back to 13.5 billion years. The new star called 2MASS J18082002-5104378 B was formed very early on when there were no metals. The stellar body, which has the lowest metal content than any star ever discovered, is only around 10% of the mass of the Sun, researchers said.
