The age of the Methuselah star (HD 140283) ? ?
Surely the age of the Methuselah star (HD 140283) cannot be greater than the age of the universe widely accepted as 13.787 ± 0.020 billion years ?
Yet calculations for Methuselah quote the age estimate as 14.27 ± 0.38
billion years and those two error ranges do not quite overlap.
Should the age of the Methuselah star be quoted as close to 13.89 billion years
with an error bar not clear yet ?
What does NASA say about the dilemma?

It means there is a factor that we do not yet know about either in how to measure the age of the Universe or the age of a star.

A mistake was made. Astronomers are not perfect. I would trust the age of the universe and say the age of that star is wrong.
By the way, NASA doesn't measure age of stars. Astronomers do that.
