Who said that it’s mandatory to travel for billions of miles in space in order to find keys for unlocking mysteries of the whole solar system? The missing piece of the puzzle could be right in our own backyard sometimes, and we’re glad to present the outcome of a new study.
Deep-sea sediments represent the unusual place where scientists had recently found evidence that our Earth has been passing through supernova remnants. This passing unfolded for tens of thousands of years, and it grants a new perspective for the space surrounding our solar system.
Isotope iron-60 was an unexpected discovery
Professor Anton Wallner conducted the research at the ANU Heavy Ion Accelerator Facility (HIAF), and isotope iron-60 was found in deep-sea sediments after scientists had been using the extreme sensitivity of HIAF’s mass spectrometer. This isotope is born within the cataclysmic explosions of supernovae.
Scientists also calculated that iron-60 formed itself later than our planet as we pretty much know it today. The isotope is likely to have been arriving on our planet due to a supernova’s explosion.
Anton Wallner said:
“There are recent papers that suggest iron-60 trapped in dust particles might bounce around in the interstellar medium,”
“So the iron-60 could originate from even older supernovae explosions, and what we measure is some kind of echo. More data is required to resolve these details.”
Astrophysicists believe that plenty of heavy elements from the Universe such as gold, zinc, iron, uranium, and others – were created along with the tremendously huge explosions of supernovae. Oddly enough, all the hydrogen from our bodies and from all the Universe was created within the Big Bang itself. Hydrogen is the most widespread and simplest element known in our physical reality.
The study led by Wallner was published in the journal PNAS.
