Where did radioactive alien debris come from at the bottom of the earth’s oceans?

(ORDO NEWS) — Researchers at the Australian National University have discovered that our planet was bombarded with radioactive isotopes after several supernova explosions in the distant past.

In the bowels of the crust under the Pacific, Atlantic and Indian oceans, a high content of radioactive isotopes of iron Fe-60 was revealed.

The study showed that these particles hit the Earth more than a million years ago as a result of supernova explosions.

For example, one supernova exploded about 2.3 million years ago and was about 9.2 times as massive as the Sun.

The second star exploded about 1.5 million years ago and was almost 8.8 times heavier than the Sun. Both cosmic explosions occurred at a distance of about 196-424 light years from Earth.

In a massive study spanning 11 million years of our planet’s life, in 2016 a team of scientists collected 120 samples from the bottom of several oceans.

The radioactive isotope Fe-60 has a half-life of 2.6 million years, and all its samples preserved on Earth are of extraterrestrial origin.

This happened, according to scientists, due to the fact that approximately 1.7-3.2 million years ago our planet was bombarded several times with radioactive debris after the explosion of supernovae.

The researchers’ hypothesis is also confirmed by periods of corresponding climatic changes.

In the meantime, most recently, the brightest supernova explosion in history occurred:
