According to scientists at Australian National University, relatively recently snow fell in Antarctica in which it was discovered rare isotope – iron-60. This was reported by Physical Review Letters.
As a result of a thorough study of this isotope, scientists suggested that he came to Earth straight from space. Isotope iron-60 most likely arose as a result of the explosion of one space object. The very same element hit our planet about twenty years ago.
Scientists suggest that a supernova explosion has had a life on Earth is a significant influence. In support of this, scientists are talking about mass extinctions on the planet. Other than that, about it evidence of a rare isotope with a decay period of 2.6 million years. Substances were discovered on the ocean floor which are more than two million years old.
According to preliminary estimates of scientists, iron-60 continues to settle on the surface of the earth. The researchers collected about 500 kilograms of snow near the German Arctic station Konen and sent to Germany in a non-melted form. It was found in 73 thousand atoms of iron-60.
