The True Reason Mars is Red: A Groundbreaking Discovery That Could Change Our Understanding of the Red Planet Introduction For decades, scientists have believed that Mars’ red color is due to iron oxide, or rust, formed over billions of years through slow oxidation. However, new research suggests an alternative explanation—one that could reshape our entire perception of Mars' history, atmosphere, and even its potential for past life. Traditional Explanation for Mars’ Red Color Mars appears red due to the abundance of iron oxide on its surface. The prevailing theory suggested that iron-rich rocks slowly rusted over millions of years due to exposure to water and a thin atmosphere. This theory supported the idea that Mars once had a warm, wet past.  New Findings: A Different Process at Work Recent studies suggest that Mars’ iron-rich dust may have turned red due to a completely different oxidation process. The oxidation could have been driven by chemical reactions involving peroxides ...

100,000 Years of Cosmic Fire: How a Supernova May Have Sparked an Evolutionary Leap on Earth Introduction Around 2.5 to 8 million years ago , a massive supernova explosion occurred relatively close to Earth, bombarding our planet with cosmic radiation for nearly 100,000 years . Scientists believe this event may have accelerated evolutionary changes , influencing early human ancestors and shaping the planet’s environment. This discovery challenges our understanding of how external cosmic events can impact Earth’s biological and climatic history. What is a Supernova and How Did it Affect Earth? A supernova is the violent explosion of a massive star , releasing an immense amount of energy and radiation.
