Scientists have discovered supernova traces near Earth

Scientists representing the Technical University of Munich have discovered supernova trails near the Earth. Presumably, it happened 2.5 million years ago – and the onset of the Ice Age may be associated with this phenomenon.

A star, the mass of which is 10 times that of the Sun, ends its “life” with a Big Bang – a supernova. This phenomenon is accompanied by the release of manganese-53 and iron-60. By the way, manganese-55 is much more common on Earth, with an indicator of 53 it is extremely rare.

Physicists were observing the star Betelgeuse when it began to lose its brightness. This meant that the space object would soon explode. Scientists were seriously worried, because a supernova could harm the Earth, but this did not happen.

At this time, scientists recorded supernova traces from the past. Iron-60 and manganese-53 were found in the layers of the earth's manganese crust. As physicist Gunter Kornischek explains, the presence of such elements indicates a supernova. It is believed that the star was far enough from the planet, but the explosion provoked a burst of cosmic rays over several millennia. The result was large clouds of cosmic dust.
