Abstract
“Does life exist beyond Earth?” is one of the major questions of astrobiology (Ćirković, 2006; Cockell, 2002; Des Marais et al., 2008; Des Marais and Walter, 1999). This question is tackled by searching for biosignatures, namely remnants of processes and structures of biological origin (Des Marais et al., 2008; Des Marais and Walter, 1999; Gargaud, 2011). Biosignatures of critical importance include anomalous sulphur and carbon isotope ratios, hopanoids and magnetite chains (Chela-Flores et al., 2007; Des Marais et al., 2008; Ohmoto et al., 2008; Slater, 2009; Bell et al., 2015).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
