A new study proposes that the Sun swallowed a super-Earth-sized planet early in its history, potentially explaining long-standing discrepancies between solar models and observations, including the Sun's depleted lithium levels and internal structure.
The article explores the scientific and mythological perspectives on Earth's ultimate fate, discussing the potential for Earth to be engulfed by the expanding Sun or to survive as a lifeless husk, and how cultural stories reflect our understanding and fears of cosmic end scenarios. It also considers the possibility of rebirth or renewal in the universe's long-term evolution.
The giant planet Halla has defied the odds by surviving the engulfment of its dying star, Baekdu. Scientists propose that Baekdu may have formed from the merger of two stars, preventing it from growing large enough to swallow Halla. Alternatively, Halla could be a newborn planet that formed from the debris of the stellar merger. However, Halla's survival is temporary, as Baekdu is expected to expand again in the future. This discovery suggests the existence of other death-defying planets in the galaxy and calls for further research on star-planet interactions and stellar mergers.
For the first time ever, scientists have witnessed a star system devouring a Jupiter-sized planet, providing a blueprint for finding similar phenomena throughout the universe. This discovery will be especially important when the Vera C. Rubin Observatory goes online in 2025. As the sun-like star consumed the planet whole, it flung the star's hot gas out into space, where it eventually cooled and turned to dust. This event is a direct observation of the eventual fate of the Earth, which will be consumed by the sun in about 5 billion years.
Astronomers have observed the first direct evidence of a dying, ancient sun-like star devouring an exoplanet using the Gemini South telescope in Chile. The outburst from the star is a signature of a planet skimming a star's surface. Such events are estimated to occur only a few times each year across the entire Milky Way. The work was published in the journal Nature and researchers are searching for similar events happening elsewhere in the cosmos with improved metrics.
Astronomers using the Gemini South telescope in Chile have observed the first direct evidence of a dying sun-like star engulfing one of its planets, which may be a preview of the ultimate fate of Earth when our own sun nears the end of its life in about five billion years. The event was seen in a long and low-energy outburst from the star, and the process would put the brakes on the planet's orbital velocity, causing it to plunge into the star. This discovery provides new insights into the evolution and final fates of planetary systems, including our own.
