Mars May Have Been Habitable for 200 Million More Years
In a groundbreaking revelation, new research suggests that Mars, the Red Planet, could have sustained life for a significantly longer period than previously thought. The findings indicate that Mars might have been habitable for an additional 200 million years, pushing the timeline of potential life on the planet back to around 3.9 billion years ago.
The Role of Mars' Magnetic Field
At the heart of this discovery is the understanding of Mars' magnetic field. A strong magnetic field is crucial for protecting a planet's atmosphere from the harsh solar winds and cosmic radiation, creating a stable environment that could support life. According to the latest studies, Mars' magnetic field may have persisted for 200 million years longer than earlier estimates, which had suggested it disappeared around 3.7 billion years ago.
