Radioactive dust from stellar explosions has been discovered in Antarctic glaciers. Scientists say this finding provides important clues about the history of our solar system.
According to Space.com, researchers found iron-60 isotope in Antarctic ice, a telltale sign of supernova explosions.
Lead researcher Dominik Koll stated: 'If iron-60 condenses into dust particles, it can penetrate the Sun's protective layer and reach Earth.'
The team analyzed over 300 kg of ice samples aged between 40,000 and 80,000 years. Using accelerator mass spectrometry, they identified and counted individual atoms of the isotope.
