25mn-year-old dust on ocean floor at odds with Supernovae hypotheses
Researchers have recently analysed galactic dust from the last 25 million years that has settled on the ocean floor, which has provided new insight into supernovae theories.
They have analysed extraterrestrial dust thought to be from supernovae, which has settled on ocean floors to determine the amount of heavy elements created by the massive explosions.
Anton Wallner, from the Research School of Physics and Engineering at The Australian National University (ANU), said that small amounts of debris from these distant explosions fall on the earth as it travels through the galaxy.
