Marie-Julie Bourgeois, Barthélemy Antoine-Lœff (artists) & Cédric Pilorget (astrophysicist and teacher at Université Paris-Sud, Institut d’Astrophysique Spatiale (IAS), CNRS/Université Paris-Sud) //


"And if the sky was falling upon us?" about the project Nos météores (project supported by La Diagonale Paris-Saclay)


Those beautiful shooting stars that we love trying to spot during August night sky are meteorites, burning when entering our atmosphere. But, they might also be some parts of a satellite falling back on Earth .... This August, it has also been night during the day in São Paulo ...


Human pollution has reached the Earth orbit, climate change is underway, and studies for other celestial bodies geo-engineering has started.

Under the title Nos météores the artists Marie-Julie Bourgeois and Barthélemy Antoine-Lœff are proposing several projects in collaboration with scientists among which what they call "atmospheric fictions" based on the real climat of other planets, including Mars with the astrophysicist Cédric Pilorget, in an attempt to poetically repair our climat.

"Life at the edge" about the project Roscosmoe


It is almost a whole zoo that has been launched into outer space. The Roscosmoe project, at the intersection of marine biology, design anthropology of science and art, intends to take on board Symsagittifera roscoffensis. This marine worm from the Breton coastline, a "plant-animal" 3 to 4 mm long, actually lives in symbiosis with a micro algae which it shelters under its epidermis and which supplies the essential of its nutritive needs via its photosynthethis.


The biology of S. roscoffensis makes this marine species a potential model for the development of bio-regenerative life-support systems applied to space research: oxygen production, recycling of CO2 and waste nitrogen metabolism from the animal by hosted micro-algae, regenerative capacities of tissues energy autonomy ("embedded photosynthesis"). 

Should we be dreaming of an algae-worm as a companion to watch the sunset at the Earth-Space edge?

LASER (Leonardo Art Science Evening Rendezvous) Talks is Leonardo's international program of evening gatherings that bring artists and scientists together for informal presentations and conversations. LASER Talks were founded in 2008 by Bay Area LASER Chair Piero Scaruffi and are in over 30 cities around the world. To learn more about how our LASER Hosts and to visit a LASER near you please visit our website

The mission of the LASERs is to provide the general public with a snapshot of the cultural environment of a region and to foster interdisciplinary networking.
