A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments.
Professor Anton Wallner, a nuclear physicist at ANU Research School of Physics, led the study which shows the Earth has been travelling for the last 33,000 years through a cloud of faintly radioactive dust.
‘These clouds could be remnants of previous supernova explosions, a powerful and super bright explosion of a star’ Professor Wallner said.
The findings are published in the journal PNAS.
