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. When a star reaches the end of its life cycle, it undergoes a sudden collapse, leading to a cosmic explosion that sends high-energy particles across space. Scientists believe that a supernova explosion in our cosmic neighborhood bombarded Earth with cosmic rays for nearly 100,000 years...

  A supernova six million years ago bathed Earth in cosmic radiation, possibly accelerating evolution 

Cosmic Explosion That Changed Life on Earth: How a Supernova 6 Million Years Ago Supercharged Evolution Scientists believe that a supernova explosion that occurred around six million years ago could have played a significant role in accelerating the course of evolution on Earth. This cosmic event might have influenced climate changes, mutations, and environmental shifts that shaped the development of life forms. Below is a detailed explanation of how this supernova event could have impacted evolution. The Supernova Event and Its Timing A supernova is the explosive death of a massive star, releasing enormous amounts of energy and cosmic radiation. Around six million years ago, a supernova is believed to have exploded relatively close to Earth, approximately 150 light-years away. Evidence of this explosion has been found in deep-sea sediments containing isotopes like iron-60 (Fe-60) , which is a telltale sign of supernova remnants. Cosmic Radiation and Its Effect on Earth's Atmospher...

Meet Vasuki Indicus: The World's Largest Snake Unearthed Recently, scientists discovered a new species of an extinct snake, Vasuki Indicus , which is now considered the largest snake ever found . This prehistoric reptile roamed the Earth millions of years ago and belonged to the same family as the giant Titanoboa. Here’s a detailed explanation of this remarkable discovery: Discovery and Naming The fossil remains of Vasuki Indicus were unearthed in India , making it one of the most significant paleontological discoveries in recent history. The name " Vasuki " comes from Hindu mythology, referring to the serpent king Vasuki , who is wrapped around Lord Shiva’s neck. " Indicus " signifies its Indian origin. Size and Characteristics Scientists estimate that Vasuki Indicus was around 15 to 20 meters (50 to 65 feet) long , making it longer than a school bus ! It weighed several hundred kilograms, making it the heaviest snake ever recorded . Its body structure suggest...
