Find the oldest star in the universe

Australian scientists have discovered the oldest star in the universe, formed 13.7 billion years ago, shortly after the Big Bang.

'This is the first time we can confirm that we have found the chemical fingerprint of the oldest star in the universe ' - Huffington Post newspaper quoted researcher Stefan Keller of the University's School of Astronomy Studies Australian country.

The Australian National University team observed a trace of the star from Siding Spring Astronomical Observatory on January 2. Later, astronomers in Chile confirmed this discovery when observing the star with the Magellan telescope.

The star lies about 6,000 light-years from Earth, a fairly close distance. Earlier, the record for the oldest star was HD 140283 , about 13.2 billion years old. Australian National University experts say the 13.7 billion-year-old star is the second generation star, born after primitive stars die.

By studying the chemical composition of the star 13.7 billion years old, scientists will better understand the formation of the universe.'This discovery helps us better understand the position of humanity in the universe. What we see is the source of all the material around us, 'said Dr. Keller.

Scientists say that apart from this star, it is possible that second generation stars still exist in the universe. However, it is difficult to detect them.
