Un énorme iceberg s'est détaché du glacier Pine Island en Antarctique Un fragment du plus gros glacier flottant d'Antarctique, le Pine Island s'est officiellement détaché cette semaine. Depuis des mois, les scientifiques surveillaient les failles apparues en octobre 2011. Il semble aujourd'hui que le processus soit terminé formant un iceberg de la taille de la ville de Hambourg. Avez-vous déjà partagé cet article? Partager sur Facebook Partager sur Twitter Cela faisait des mois que les géologues s'attendaient à un tel évènement mais il n'en reste pas moins spectaculaire. C'est pour la première fois, en octobre 2011, qu'une faille de 24 kilomètres avait été repérée dans la glace creusant un espace de 50 mètres de large. En effet, la largeur du trou mais aussi la vitesse à laquelle celui-ci se creusait constituent des détails importants afin de prévoir sa future activité. Un fragment de la taille d'Hambourg Les images prises par le satellite ont permis d'établir le modèle de la fracture et de comprendre le mécanisme de mouvance des masses de glace.
Black Holes: Gravity's Relentless Pull Black holes are places where ordinary gravity has become so extreme that it overwhelms all other forces in the Universe. Once inside, nothing can escape a black hole's gravity — not even light. Yet we know that black holes exist. We know how they are born, where they occur, and why they exist in different sizes. The nearest black hole is many lightyears away, so we don't have to worry about threats to the Earth.

WTF Is Falling to Earth!! Asteroid ?? Comet? UFO? 2011! Weird Event.... Explore Space Science Activities Overview Jump Start: Jupiter! is a 60-minute kick-off for children ages 8 to 13 that sets the stage for further explorations and activities in Explore! Jupiter's Family Secrets. What's the Point? The solar system is a family of eight planets (four giant planets and four inner, rocky planets), an asteroid belt, several dwarf planets, and numerous small bodies such as comets in orbit around the Sun. Materials For each group of 20 to 30 children: For each child: For the facilitator: Preparation Review the complete background information. Activity 1. How many stars are in our solar system? 2. 3. What is its surface like? 4. 5. 6. How are the four giant planets alike? Invite the children to summarize their findings in their journals. 7. Scientists still have many questions about our solar system, and other missions to Mercury, the Moon, Mars, Ceres and other asteroids, the dwarf planet Pluto, and comets will send back information about our solar system family!

METEORITE ELENIN TWO WEEKS PREPARE PROOF SIGNS NOW Liège at Night To paraphrase an old expression: “all roads lead to Liège.” Or at least you could get that impression from this astronaut photograph. The brightly lit core of the Liège urban area appears to lie at the center of a network of roadways—traceable by continuous orange lighting extending out into the rural and relatively dark Belgian countryside. For a sense of scale, the distance from image left to right is approximately 70 kilometers (43 miles). The image was taken using the European Space Agency’s Nodding mechanism on the International Space Station (ISS), also known as the NightPod. Liège is the third most populous metro area in Belgium, after Brussels and Antwerp. Astronaut photograph ISS034-E-5935 was acquired on December 8, 2012, with a Nikon D3S digital camera using a 180 millimeter lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center.
