Detecting mysterious "cosmic matter" at the bottom of Russia's lake

An unusual layer of bright yellow sediment at the bottom of Lake Zapovednoye is believed to be cosmic matter, evidence of an attacker from space that caused the Tunguska event 110 years ago.

In 1908, something with the power of 10-20 million tons of TNT tore through the sky of Siberia in Russia, causing a forest area up to 2,150 square kilometers to collapse in an instant. All that the indigenous people of that year was a pillar of blue light “as bright as the sun” gliding across the dawn sky. Then, a terrible explosion accompanied by an invisible wave smashed the windows of houses, knocking everyone down.

The most mysterious thing is that everyone only felt the sound and the invisible tremor, no one saw the explosion. That same day, seismic stations across Europe and Asia recorded unusual fluctuations in atmospheric pressure. A strange event believed to be related is that the night sky in some places suddenly glowed in a bright red light several days later. Absolutely no craters have been found.

To solve this 112-year-old mystery, Russian scientists from the Novosibirsk Institute of Nuclear Physics, the Novosibirsk Institute of Geology and Mineralogy, the Tunguska Nature Reserve and the Krasnoyarsk Institute of Physiology decided to find ” specter” of what caused the Tunguska incident. They believe that it must be a meteorite exploding right on the surface of the lake to create the above mysteries.

According to biologist Dr Arthur Meidus, deputy director of a Tunguska Nature Reserve, a member of the research team, they found the first valuable evidence: a prominent bright yellow layer in the sediments the bottom of Lake Zapondnoye.

The composition of the sedimentary layer, with mainly potassium, titanium, rubdium, yttium, zirconium… is similar to that found in the remnants of other meteorite impacts. In other words, it is most likely the same cosmic material that the meteorite that caused the Tunguska explosion brought to Earth.

That won’t be the only sediment to be analyzed . “In this way, we will know which sediments may contain particles of extraterrestrial origin,” said Meidus.

According to the authors, uncovering the mystery of the Tunguska event could help them draw useful lessons about the danger posed by “invasion” from space, thereby planning appropriate defense.
