Multiple reports say scientists have updated expectations for the distant end of Earth by re-examining how the Sun evolves. The long-standing view is that, as the Sun ages, it will expand and ultimately engulf the inner planets, potentially including Earth, in roughly five billion years. The new study described by the outlets argues that this scenario may be less certain than previously thought. Rather than assuming Earth will definitely be swallowed as the Sun grows, the research suggests alternative outcomes depending on details of stellar expansion and the changing conditions around the planet. While the articles present the earlier “Earth swallowed by the Sun” framing as a widely held belief, they characterize the new work as indicating Earth may not necessarily end up engulfed, even if the Sun’s later-life evolution still threatens planetary habitability. The reports do not provide additional specific figures or methodological details in the provided text, but they consistently point to a revision of the expected fate of Earth during the Sun’s far future expansion, emphasizing uncertainty in the exact end state.
