keep up the good work my man... Thread: Riding the Interface Region Solar Journey: The Significance of our
Galactic Environment for the
Heliosphere and EarthPriscilla C. Frisch University of Chicago, IL, USA Humans evolved when the Sun was in the great void of the Local Bubble. The Sun entered the present environment of interstellar clouds only during the late Quaternary. Astronomical data reveal these long and short term changes in our galactic environment. Theoretical models then tell us how these changes affect interplanetary particles, planetary magnetospheres, and the Earth itself. Cosmic rays leave an isotopic signature in the paleoclimate record that helps trace the solar journey through space.
"Solar Journey: The Significance of Our Galactic Environment for the Heliosphere and Earth" lays the foundation for an interdisciplinary study of the influence of interstellar material on the solar system and Earth as we travel through the Milky Way Galaxy.
The solar wind bubble responds dynamically to interstellar material flowing past the Sun, regulating interstellar gas, dust, and cosmic particle fluxes in the interplanetary medium and the Earth. Cones of interstellar gas and dust focused by solar gravity, the magnetospheres of the outer planets, and cosmic rays at Earth all might yield the first
hints of changes in our galactic environment. [ link to astro.uchicago.edu] Quoting: Septenary Man Quoting: Septenary Man |
