Scientists reviewing current models of the Sun’s evolution say Earth may not be engulfed during the Sun’s later red-giant phase, according to reports carried by Phys.org and Yahoo News UK. The coverage points to updated calculations that reassess how far the Sun’s outer layers will expand as it ages, and how that expansion interacts with factors such as mass loss and changes in the Sun’s radius over time. While earlier studies sometimes suggested Earth could be engulfed, the new estimates indicate the maximum reach of the Sun’s atmosphere may fall short of Earth’s current orbital distance. The reports present the revised conclusion as dependent on uncertainties in stellar evolution parameters and modeling choices, meaning the outcome is not framed as fully settled. Overall, the articles describe ongoing scientific work that refines predictions for the far future, emphasizing that results can change as researchers improve the underlying physics and observational constraints.
