The evolution of Venus and Venus-like Exoplanets

Session ID#: 80203

Session Description:
Today Venus appears to be hostile and uninhabitable. However, recent studies have shown that its climate evolution is complex and could permit early habitable conditions (e.g. Way et al. 2016). Other recent studies of Magellan imagery have demonstrated the possibility that many tesserae on Venus are some of the oldest geological surface units visible today (e.g. Gilmore et al. 2017) and may predate much of the near-global resurfacing. The idea that Venus is a static single plate planet has also come into question with the studies of Davaille et al. 2017 and Byrne et al. 2018. All of these studies have implications for the understanding of Venus-like Exoplanets (Kane et al. 2014) to be discovered in the near term. This session will explore recent advances in understanding the evolution of Venus and Venus-like exoplanets and how they may inform each other.
