Can supernovae cause extinctions!?
2016-11-22 – Recently, the research group of Prof. Shawn Bishop have for the first time ever identified supernova ash in the Earth’s microfossil record. They found out that our earth moved through – or rather was bombarded by – the remnants of a supernova explosion, starting about 2.7 million years and lasting for about a million years. Now a Canadian radio programme has aired an extensive inteview with Shawn Bishop, which is available online. Additionally, a radio essay featuring this work via the “Academic Minute” has been broadcast in the US, and is also available online.
Time-resolved detection of a supernova signal in Earth’s microfossils
2016-08-10 – Physicists from the Technical University of Munich (TUM) have succeeded in detecting a time-resolved supernova signal in the Earth’s microfossil record. As the group of Prof. Shawn Bishop could show, the supernova signal was first detectable at a time starting about 2.7 Million years ago. According to the researcher’s analyses, our solar system spent one Million years to transit trough the remnants of a supernova.
