We use the most up to date Milky Way model and solar orbit data in order to test the hypothesis that the Sun's galactic spiral arm crossings cause mass extinction events on Earth. To do this, we created a new model of the Milky Way's spiral arms by combining a large quantity of data from several surveys. We then combined this model with a recently derived solution for the solar orbit to determine the timing of the Sun's historical passages through the Galaxy's spiral arms. Our new model was…

Mapping the location of terrestrial impacts and extinctions onto the spiral arm structure of the Milky Way
Abstract High-density regions within the spiral arms are expected to have profound effects on passing stars. Understanding of the potential effects on the Earth and our Solar System is dependent on a
The Dynamical Origin of the Local Arm and the Sun's Trapped Orbit
The Local arm of the Milky Way, a short spiral feature near the Sun whose existence is known for decades, was recently observed in detail with different tracers. Many efforts have been dedicated to
Dynamics of the Spiral-Arm Corotation and Its Observable Footprints in the Solar Neighborhood
This article discusses the effects of the spiral-arm corotation on the stellar dynamics in the Solar Neighborhood (SN). All our results presented here rely on: (1) observational evidence that the Sun

The lunar surface as a recorder of astrophysical processes
TLDR
The lunar surface is ideally suited to collect astronomical records, because the Moon exhibits geological processes able to bury and thus both preserve and ‘time-stamp' these records, although gaining access to them is likely to require a significant scientific infrastructure on the lunar surface.
Solar System Physics for Exoplanet Research
Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos - the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the
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) supernova
Setting the Stage for Habitable Planets
TLDR
The present review focuses on recent research that bears on this topic and includes discussions of processes occurring in astrophysical, geophysical and climatic contexts, as well as the temporal evolution of planetary habitability.

The impact history of the Moon has significant implications that go far beyond simply excavating the surface of a dry and lifeless world. The age distribution of lunar impact breccias inspired the
BULLETINS OF AMERICAN PALEONTOLOGY Established 1895
TLDR
These formations are a series of fossiliferous bioclastic limestones and terrigenous clastic rocks that span the Silurian–Devonian boundary and contain diverse assemblages of echinoderms with a total of 38 genera and 69 species in 7 classes.
