About :

Afternoon Conference 5/5 Pluto as seen by a geologist The flyby of Pluto in 2015 and the exploitation of the data collected made it possible to draw up an astonishing portrait of this distant dwarf planet. Nitrogen sublimates here to condense elsewhere. The nitrogen condensed on the mountains flows towards the lower areas via vast glaciers. During episodes of global "warming", liquid nitrogen flows on the surface. This surface is crossed by immense faults whose geometry suggests the presence of an ocean of liquid water at a depth of 250 km. Pierre THOMAS Professor emeritus at the Ecole Normale Supérieure de Lyon, geologist by training, Pierre THOMAS works on the geology of planets and satellites and on the origin of the Earth and the Solar System. --- Follow us also on: Instagram: / festival_fleurance Facebook: / festivaldastronomiedefleurance Twitter: / astrofleurance --- #FAsF22 #FestivalAstronomie #Fleurance ---
