Imagine life elsewhere

Sujet :

An amazing exoplanetary system was identified in 2015, consisting of seven planets with masses like to Earth’s, orbiting a dwarf star named TRAPPIST-1. In a science fiction story centred on this system, the author examines the potential conditions for life on one of these planets, with particular focus on issues related to the perception and passage of time. Does this work rigorously consider the available scientific data regarding this system? Does it succeed in generating reader’s interest in the unique environment that would characterize this small region of our galaxy ? ?
