Physique La physique des particules – l’étude des constituants fondamentaux de la matière – constitue le principal axe des recherches menées au CERN. Toutefois, le programme de physique du Laboratoire est bien plus vaste, allant de la physique nucléaire à la physique des hautes énergies, et de l’étude de l'antimatière aux effets possibles des rayons cosmiques sur les nuages. Depuis les années 1970, les physiciens des particules décrivent la structure fondamentale de la matière à l’aide d’une série d’équations complexes, constituant le Modèle standard. Toutefois, le Modèle standard ne décrit que 4 % de l'Univers connu, et plusieurs questions restent sans réponse. Les physiciens du CERN cherchent les réponses à toutes ces questions, et bien plus encore.

Two international teams of astronomers studying these events conclude that they likely arose from the catastrophic death of supergiant stars hundreds of times larger than the sun. GRB 111209A exploded on Dec. 9, 2011. Credits: NASA/Swift/B. The astronomers discussed their findings Tuesday at the 2013 Huntsville Gamma-ray Burst Symposium in Nashville, Tenn., a meeting sponsored in part by the University of Alabama at Huntsville and NASA's Swift and Fermi Gamma-ray Space Telescope missions. GRBs are the most luminous and mysterious explosions in the universe. Three recent GRBs (blue dots) emitted high-energy gamma-ray and X-ray light over time spans up to 100 times greater than typical long bursts and constitute a new ultra-long class.

No One Wants to Live in My 'Elysium'-Style Simulation Orbital Space Colony They will also be a pain in the ass to run. And I speak from experience on this because I briefly governed my own orbital colony. My time in command did not end well. Joe Strout gave me the opportunity to fail. A software engineer with a huge background in creating complex simulations, Strout is the creator of High Frontier, which seeks to translate the mechanics of the SimCity series into a vacuum. Strout, who describes himself as “space nut,” was a childhood member of the L5 Society, an organization dedicated to advancing technology essential for building and launching orbital space colonies in the L5 orbit. Strout wasn’’t cool with that so he started programming. Part 1: Building your colony You start out by choosing whether or not to create something in low Earth orbit (which is better protected from radiation damage) or high Earth orbit (from which materials can be important from the moon for cheap). Deciding between LEO and HEO. Oh — and all this also affects your budget.
Accueil | Uved 7 Space Simulators That Let You Explore the Universe Why should Mars rovers have all the fun? If you're tired of standing by while Curiosity rolls around up there, it's time to head out on the open exosphere and explore the universe for yourself — digitally, of course. SEE ALSO: 10 Must-Follow Tumblrs for Science Lovers A handful of excellent space simulators use real astronomical data to re-create the known universe in three dimensions. Some of these simulations stick to our own solar system, while others push the boundaries of our cosmological projections, procedurally generating star systems far beyond our galactic neighborhood. If you take any of these for a spin, let us know in the comments where you traveled. NASA fr:start [Virtual Moon Atlas] Déjà téléchargé plus de 1 million 900 000 fois dans le monde entier.

Apollo 11-17 First man on the Moon - Apollo Moon Landings - QTVR photos from panoramas.dk Less known is that during all the missions they made image sequences which with today's computer technics can be stitched together into 360o interactive panoramas giving you the possibility to view the moon almost as you were there. Many of these panoramas have been published before but in low resolution and displayed in small sizes. Film used on the Moon was a modified Kodak Ectachrome 160. During the last years (2000-2005) the original films have been re-scanned in high resolution and the Apollo 11 images were released the week before the 35 year anniversary. I can now present you for the first time the Moon in interactive 360 degree full screen Quicktime VR. Stitching these images to make 360 degree panoramas is a difficult task as the astronauts did not know anything about interactive panoramas and the stitching methods which would come 25 years later. Besides stitching them to panoramas the images are kept as much as possible in their original All images are credit NASA Related Links:
MARS Rover Virtual Reality Panoramic images - 360 degree QTVR Photos from panoramas.dk A Great Place to Watch the Weather - Dust devils The martian wind sends hundreds of dust devils spinning across the surface of the planet. From Spirit's high perch approximately 90 meters (295 feet) above the surrounding plains, as shown in this image taken from the summit of "Husband Hill," three dust devils are clearly visible in the plains of Gusev Crater. Planetary Scientist Ron Greeley of Arizona State University, Tempe, describes the whirling vortices of wind and dust as "vacuum cleaners" that were first seen in images from the Viking Orbiter in 1985, though their existence was predicted as early as 1964. The largest dust devil in this 360-degree panorama, is one of the closest seen by Spirit. You can see 2 more dustlevels in the panorama. Spirit took this mosaic of images with its navigation camera on sol 581 (Aug. 22).
