Earth is traveling through a massive dust cloud since 33,000 years – Tech Explorist
The traces of isotope iron-60 found in deep-sea sediments suggests that the Earth has been traveling for the last 33,000 years through a cloud of faintly radioactive dust.
Nearby supernova explosions shape the interstellar medium. Ejecta, containing fresh nucleosynthetic products, may traverse the solar system as a transient passage, or alternatively, the solar system may navigate local clouds that may represent isolated remnants of supernova explosions.
Such scenarios may modulate the galactic cosmic-ray flux intensity to which Earth is exposed.
