Carissimi Associati SGI,
Carissimi Soci Società Associate,
su indicazione del Prof. Rodolfo Carosi (Università di Torino e Presidente SGI) vi segnaliamo l'ultimo podcast di Geology Bites (Conversations about geology with researchers making key contributions to our understanding of the Earth and the Solar System):
Di seguito troverete il messaggio dell'ideatore, Oliver Strimpel, e il link al sito web di Geology Bites.
Cordiali saluti,
La Segreteria SGI
Hello, listeners,
In this episode, I talk to Anat Shahar, a researcher at the Carnegie Institute for Science in Washington DC.
Since we think any form of life requires liquid water, at least at some stage in its life, we would like to know how likely it is for an exoplanet to have water. It is not only a question as to whether a planet is in the so-called Goldilocks zone (not too hot, not too cold), but also whether there is any water there to begin with, in whatever phase.
In the podcast, Shahar describes the work she and her team have done that strongly suggests that water could form as a natural by-product of planet formation when a protoplanet's hydrogen atmosphere reacts with an iron-rich magma ocean. Perhaps this means that water is not rare at all, but rather the norm for planets in the habitable zone around their star.
I hope you enjoy listening.
Oliver
