Summary
DescriptionArtist's concept of collision at HD 172555.jpg |
English: This artist's concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury. NASA's Spitzer Space Telescope found evidence that a high-speed collision of this sort occurred a few thousand years ago around a young star, called HD 172555, still in the early stages of planet formation. The star is about 100 light-years from Earth.
العربية: تصور لفرضية الاصطدام العملاق التي يعتقد أنه شكّل القمر.
Français : 70 à 95 % de l'eau de la Terre daterait d'avant la formation de la Lune issue de l'impact de Théia sur la Terre. Cet impact aurait entraîné la volatilisation d'une partie de l'eau déjà formée mais la majorité serait restée condensée, ce qui impliquerait que seulement de 5 à 30 % de l'eau de la Terre provienne d'un apport extra-terrestre (comètes et météorites) ultérieur (source |
