Mars could have conditions suitable for life, reveals new discovery

economictimes.indiatimes.com:

Mars might have shared more similarities with Earth than previously understood, potentially featuring distinct wet and dry seasons that could have supported life. Through the discovery of fossil evidence, researchers have unveiled indications of a cyclical climate on the Red Planet over three billion years ago, according to reports.

This alternating pattern of wet and dry periods is believed to have created an environment conducive to the development of complex ancient organic compounds. These compounds could have acted as precursors to life, indicating that Mars could have hosted conditions suitable for life's emergence.

The research outcomes, documented in the journal Nature, not only expand our understanding of Mars but also offer fresh avenues for exploring the natural mechanisms that led to the genesis of life. The study underscores a consistent, cyclic climate in early Mars, possibly characterized by seasonal variations that could have supported prebiotic evolution.

In contrast to Earth's tectonic plate system, Mars possesses extensive expanses of remarkably well-preserved landscapes, including fossilized rivers and lakes dating back billions of years. While Mars currently presents a cold and inhospitable environment, evidence hints at a past state where liquid water – a critical component for life – and a dense atmosphere might have existed.

Over vast epochs, Mars underwent a significant loss of atmosphere, causing its climate to shift from one that might have sustained life to its current arid and frigid state, as per reports. To conduct their study, a team of researchers from the French National Centre for Scientific Research (CNRS), Paul Sabatier University, and Claude Bernard University Lyon 1 in France delved
