“Combining astrophysics and geology to study the formation of Earth and Venus”

The accretion of Earth is a mysterious era in geologic history without any surviving rock record. However, this is when Earth's bulk geochemistry and geophysical structure was established. Using sophisticated astrophysical-geological modeling, we can reconstruct this era, date important events such as the Moon-forming event, and determine basic characteristics of the nascent protoplanetary disk. By considering the consequences for Earth, we can better understand the stark contrast of Venus--a planet without a planetary magnetic field, without plate tectonics, and without a Moon. This earliest eon which lies at the intersection of astrophysics and geology had profound consequences for life on Earth that are just beginning to be understood.
