HD140283

THE STAR BAFFLED SCIENTISTS WHICH LOOKS OLDER THAN OUR UNIVERSE 

The age of our universe is 13.8 billion years. Scientists found a star who baffled them by it's age. Scientists have discovered star whose age is 14.5billion years. Now question is can our universe have stars older than itself?  This is condrum that universe is younger than its some stars. 

HD 140283 :

HD 140283, informally nicknamed the Methuselah star, is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, specifically toward Ophiuchus. Its apparent magnitude is 7.205. 

It's a riddle of cosmic proportions: how can the universe contain stars older than itself?" physicist Robert Matthews wrote for The National, an English-language newspaper published in UAE.

It could spark on new scientific revolution. Dr Matthews, a member of the UK's Royal Astronomical Society, said recent measurements of the cosmic background radiation left over after the Big Bang very precisely show the universe to be 13.8 billion years, plus or minus about 20 million years.

But in 2013, measurements suggested HD140283 dubbed the -Methuselah star said the biblical said to lived to ripe old age of 969 was about 14.5 billion years ago based on low metal content. 

Astronomers now confirmed that HD140283 contains low quantity of iron. "This shows this iron must be formed before it became universal common element,so this star is as old as our universe"Dr. Matthew said

The estimation made by NASA is imprecise. If age of HD140283 is 14.5 billion years means it's 800 million years older than our universe which too big numbers. It is possible it may be 800million years younger or older than universe but that leaves it younger than universe.
