The book is written between five researchers from several disciplines, including our astronomer and professor Carme Jordi. The other co-authors are the IEEC director and CSIC astrophysicist Ignasi Ribas; the geophysicist Daniel García-Castellanos form the Institut de Ciències de la Terra Jaume Almera (CSIC ICTJA) and the microbiologist and IRBio researcher Jordi Urmeneta.
The book deals with the possibility of the existence of life beyond our planet, with astrobiogeology as a meeting point for multiple disciplines that invite both debate on accepted paradigms and discourse of a more speculative nature.
