” There are those who will be disappointed if no life is found on other planets. Not me — I want to be thrilled and surprised once again, through interplanetary exploration, and reminded of the infinite variety and novelty of phenomena that can be generated from such simple laws and equations of the physical. The test of science is its ability to predict. If you had never visited Earth, could you predict the thunderstormsthe volcanoesthe waves of the ocean, the dawns and the sunsets of sun colorful? It will be a salutary lesson when we learn everything that happens on each of these dead planets, these eight or ten balls, each agglomerated from the same cloud of dust and each obeying exactly the same laws of physics “.
So said in the early 1960s, in his famous Physics coursesthe mythical Nobel Prize in Physics Richard Feynman. Years later, the Voyager and Cassini missions would prove him right by showing the diversity of the planetary worlds around the giants of gas and ice like the late André Brahic testified to this in an interview he gave to Futura.
The diversity of Solar system can also be seen in the interiors of stars that we invite you to visit a little in this slideshow showing both that of the Sun and of the moons of Jupiter passing of course by the Earth.
