The brand new Snapchat space series has just been launched by Futura: Swipe Into Space! On the program, answers to the many questions we ask ourselves about the cosmos. For this third episode, relive the somewhat sensational birth of our satellite, the Moon!
Notice to lovers of SnapchatFutura is launching a brand new children’s series on space and the sciences of the Universe: Swipe Into Space. Through dynamic episodes of approximately three minutes, sprinkled with grandiose illustrations and face-to-face sequences, you will discover many mysteries of the cosmosof the edge of the universe to the formation of our planet.
Each week, Thibaut at Futura will answer one of the many questions we might ask. VSow was the Moon formed? What is the Starshipthis rocket new generation that promises to send men to Mars? How does a spacewalk take place? What fate awaits our Universe? What if we could travel to the speed of light ?
In this third episode: the birth of the Moon
In this third episode of Swipe Into SpaceThibaut sheds light on the moon birth, which took place 4.5 billion years ago. The Earth, still in the process of formation, was then devoid of a satellite, but a protoplanet named Theia changed the situation. Of a size similar to that of the planet Mars, it would have violently struck the Earth, to the point of expelling into space large quantities of matter. The ferrous core of Theia would have merged with that of the Earth, while the external dust would have agglomerated by gravitation, thus forming… the Moon!
The Moon therefore results from this collision, hence the many similarities between its composition and that of the Earth. Today, this celestial body has a large amount of scars on its surface: in question, its absence ofatmosphere protector, and of course, the many asteroids that hit it. In particular at the South Pole, where the gigantic South Pole-Aitken basin of 2,500 kilometers in diameter comes from an impact between our satellite and an imposing asteroid. And these craters remain visible today because on the Moon, there is no erosion! Each impact remains engraved there indefinitely, contrary to the Earth, where the natural geological phenomena tend to smooth the surface. What if it contained ice? To find out more, you will have to go to Swipe Into Space !
