At a time when space travel is attempting to extend humanity beyond the Earth, two astrophysicists are grappling with their own memories, nostalgic for the exoplanets they are studying by optical interferometry. They question the memory of these places they have never experienced, which are like an afterimage that imprints their own ways of apprehending the future. 

Cosmic particles from deep space, detected in real time in the exhibition space, make visible another perspective of space through the Earth. At the same time, a terrestrial landscape within a real-time 3D environment reacts to the passage of these particles by sending out an ephemeral glow. 

In a fictional exploration of the imaginary of space through ecological and decolonial issues, these two researchers explore their fascination with celestial bodies. They approach another observation of space where cosmic particles bring their gaze to rest on the Earth.
