Around the year 2000, estimates for the star's age were about 16 billion years. But the universe is about 13.8 billion years old, based on a meticulous calibration of the expansion of space and analysis of the microwave afterglow from the big bang. Hubble data and improved theoretical calculations were used to recalculate the star's age and lower the estimate to 14.5 billion years, within a measurement uncertainty of plus or minus 800 million years. This places the star within a comfortable range to be younger than the universe.
