Jesse Miller

Jesse Miller investigates how events in our own Milky Way Galaxy affect Earth and the rest of the solar system. Within the last ten million years, uncomfortably close supernovae compressed the solar wind, exposing the outer planets to the harsh environment of the Galaxy. Our passage through a dense interstellar cloud may have even affected Earth’s climate. Dr. Miller uses various numerical simulations to investigate these effects, from hydrodynamic models of the heliosphere to chemistry-climate models of our atmosphere, ultimately probing multidisciplinary connections between astronomy, heliophysics, and atmospheric science.
