Title: Exploring the Curious Boundary between Life and Non-Life on the Ancient Earth and Failed System of Lost Gliese 652B
Introduction:
As our understanding of the universe expands, we continue to uncover mysteries about the origins and fates of celestial bodies. The case of Ancient Earth and the lost system of Gliese 652B is such a mysterious case that has caught the attention of astronomers and astrobiologists alike. Recent studies have uncovered intriguing details about these planets’ geological evolution and the potential for life on their surfaces, leading to a question: can we consider these planets to be extant beings in a planetary zoo or just alien astrobiological systems on course for extinction?
Background:
Ancient Earth is known as one of the oldest inhabited planets in our solar system. Its core temperature range falls somewhere between Earth’s and Mars’, implying it may still harbor steep lunar maria and could permit live forms in its oceans. Its composition consists primarily of light elements, meaning any remnants of past life would have to exist at a depth below the planet’s surface. Certain chemical phenomena, like underground hydrothermal vents or well-suited animal cells traps within primitive terrestrial lands or underglacial waters, could provide locomotion or other means for potentially contributing systems that could be viable evidence for life. March 15, 2000 marks a loss; Gliese 652B, also previously named as 62 1970, was observed via the Hubble Space Telescope
