Ancient evidence of hot water points to an early habitable Mars

Scientists have discovered the oldest evidence of hot water activity on Mars, revealing its potential for early habitability. Researchers analyzed a 4.45-billion-year-old zircon grain from the Martian meteorite “Black Beauty” and found signs of hydrothermal conditions during Mars’ early crust formation.

Using advanced microscopy, they identified minerals formed with water-rich fluids, indicating that Mars’ crust interacted with water over 4.1 billion years ago. These hydrothermal systems, crucial for life, suggest ancient Mars could have supported habitable environments. The findings also link these systems to a strong magnetic field, providing insights into Mars’ early hydrology and structure.

The research shows Mars’ crust hosted wet, dynamic conditions earlier than Earth’s, offering new clues about the planet’s habitability.
