Supernova (SN) explosions are one of the most energetic---and potentially lethal---phenomena in the Universe. We show that the Scorpius-Centaurus OB association, a group of young stars currently located at approximately 130 pc from the Sun, has generated 20 SN explosions during the last 11 Myr, some of them probably as close as 40 pc to our planet. The deposition on Earth of (60)Fe atoms produced by these explosions can explain the recent measurements of an excess of this isotope in deep ocean… Expand
60Fe anomaly in a deep-sea manganese crust and implications for a nearby supernova source.
A well resolved time profile of the 60Fe concentration in a deep-sea ferromanganese crust is measured and a highly significant increase 2.8 Myr ago is found. Expand
Live radioisotopes as signatures of nearby supernovae
Abstract Nearby (≲1 kpc) supernovae were almost certainly common in earth’s geological history. Such events allow the direct study of their freshly synthesized live radioisotopes, opening new windowsExpand
Time-resolved 2-million-year-old supernova activity discovered in Earth’s microfossil record
A time-resolved 60Fe signal residing, at least partially, in a biogenic reservoir is reported through the direct detection of live 60Fe atoms contained within secondary iron oxides, among which are magnetofossils, the fossilized chains of magnetite crystals produced by magnetotactic bacteria.

Supernova Ejecta in Ocean Cores Used as Time Constraints for Nearby Stellar Groups
Evidence of a supernova event, discussed in Wallner et al., was discovered in the deep-sea crusts with two signals dating back to 2-3 and 7-9 Myr ago. In this contribution, we place constraints onExpand
The Moon as a Recorder of Nearby Supernovae
The lunar geological record is expected to contain a rich record of the galactic environment of the Solar System, including records of nearby (i.e. less than a few tens of parsecs) supernovaExpand
Muon Radiation Dose and Marine Megafaunal Extinction at the end-Pliocene Supernova
The muon flux from supernova-initiated cosmic rays from the surface to the depths of the ocean is propagate, and it is found that the radiation dose from the muons will exceed the total present surface dose from all sources at depths up to a kilometer and will persist for at least the lifetime of marine megafauna.

The locations of recent supernovae near the Sun from modelling 60Fe transport
Calculations of the most probable trajectories and masses of the supernova progenitors, and hence their explosion times and sites, are reported and the model reproduces the measured relative abundances very well. Expand
Recent near-Earth supernovae probed by global deposition of interstellar radioactive 60Fe
The findings indicate multiple supernova and massive-star events during the last ten million years at distances of up to 100 parsecs, which indicates that a few per cent of fresh 60Fe was captured in dust and deposited on Earth. Expand
Nearby supernova explosions—within a few tens of pc of the solar system—have become a subject of intense scrutiny, due to the discovery of live undersea 60 Fe from an event 2.8 Myr ago. A key openExpand
Discovery Prospects for a Biogenic Supernova Signature
Within the universe, the astrophysical sites responsible for the production of radioactive 60 Fe, of half life 2.62 Myr, are primarily confined to two: Type 1a supernovae and massive stars that endExpand
