Using advanced ground-penetrating radar, scientists have discovered sedimentary structures resembling Earth's coastal deposits, suggesting that the Red Planet once harbored a significant body of water, potentially creating habitable environments for microbial life.Water's Early Role in the UniverseWe also discuss a new study indicating that water may have formed in the universe much earlier than previously thought, just 100 to 200 million years after the Big Bang. This discovery suggests that habitable planets could have begun forming before the first galaxies, with primordial supernovae playing a crucial role in producing the necessary oxygen for water molec
