Tobias Owen. Portrait of doctor Tobias Owen,planetary climatologist,with Galileo probe artwork in the background. Dr Owen works at the Institute for Astronomy in Honolulu,Hawaii,USA. His main studies are in the evolution of planetary atmospheres,and the conditions needed for life to flourish in them. The Galileo probe is designed to descend into the clouds of Jupiter and record data about pressure,temperature and composition. Owen realises that it is the atmosphere of a planet which makes life possible,and he and others are hoping for evidence of water and oxygen,which may form a biosphere,in extraterrestrial atmospheres |
