Ancient Martian Crystal Reveals Early Hot Springs and Potential for Life

A zircon crystal from the Martian meteorite 'Black Beauty' provides the oldest evidence of water and hydrothermal activity on Mars, offering insights into the planet's early habitability.

The zircon crystal, dated to 4.45 billion years ago, was found in the Martian meteorite NWA7034, also known as 'Black Beauty.'
Geochemical analysis revealed the presence of elements such as iron, aluminum, and sodium, indicating ancient hydrothermal systems on Mars.
The discovery suggests that Mars had hot springs during the Pre-Noachian period, similar to environments on Earth where life is thought to have originated.
The study provides new insights into the early presence of water on Mars, predating the previously known Noachian wet era by hundreds of millions of years.
Researchers believe these hydrothermal systems could have supported conditions suitable for life, advancing understanding of Mars' early habitability.
