HD 140283 (Also known as Methuselah Star) is a star located in the constellation Libra. It gained attention in the scientific community because initial estimates of its age seemed to conflict with the age of the universe as calculated using the Big Bang theory. Originally, astronomers using the Hubble Space Telescope in 2013 reported an age estimate for HD 140283 of approximately 14.46 billion years, which raised eyebrows since it appeared to be older than the calculated age of the universe (around 13.8 billion years). This apparent discrepancy led to HD 140283 being colloquially referred to as the "Methuselah star." However, subsequent studies and refined measurements, including improved distance measurements of the star, have reconciled the discrepancy. Current estimates now place the age of HD 140283 at approximately 14 billion years, consistent with the accepted age of the universe. The star is a metal-poor subgiant, and its revised age aligns with our understanding of stellar evolution and cosmology.
