The Methuselah Star

Today I learned that there is a star, called HD 140283, or more easily, the "Methuselah Star" or the "Genesis Star" that appears to be old just as the Univese itself!

(Image from Wikipedia)

It is 190.1 light-years away, its size is 1.4 times the Sun and it's age is 14.46 ± 0.8 billions of years.
As stated, its age is pretty impressive, condisidered that the age of the Universe is only 13.798±0.037 billions of years! Within the error bars, this star is just old as the Universe itself!!! The star must have formed soon after the Big Bang,
and it has perhaps the largest age purported to any star.


Other info about the Mathuselah are available at the wikipedia link.
