Peter Weyland at TED2023: I will change the world Peter Weyland has been a magnet for controversy since he announced his intent to build the first convincingly humanoid robotic system by the end of the decade. Whether challenging the ethical boundaries of medicine with nanotechnology or going toe to toe with the Vatican itself on the issue of gene-therapy sterilization, Sir Peter prides himself on his motto, “If we can, we must.” After a three year media blackout, Weyland has finally emerged to reveal where he’s heading next. Wherever that may be, we will most certainly want to follow. Conceived and designed by Ridley Scott and Damon Lindelof and directed by Luke Scott. Sir Peter Weyland was born in Mumbai, India at the turn of the Millennium. In less than a decade, Weyland Corporation became a worldwide leader in emerging technologies and launched the first privatized industrial mission to leave the planet Earth.
People: Featured People: Carl Sagan Carl Sagan played a leading role in the American space program from its very beginning. He was a consultant and adviser to NASA beginning in the 1950s -- he briefed the Apollo astronauts before their flights to the Moon. Carl was born in New York City on November 9, 1934. He described himself as a childhood science fiction addict who became fascinated by astronomy when he learned that every star in the night sky was a distant sun. In his role as a visiting scientist at the Jet Propulsion Laboratory (JPL) in Pasadena, Calif., Carl helped design and manage the Mariner 2 mission to Venus, the Mariner 9 and Viking 1 and Viking 2 trips to Mars, the Voyager 1 and Voyager 2 missions to the outer solar system and the Galileo mission to Jupiter. Carl was often described as "the scientist who made the Universe clearer to the ordinary person." Carl taught and conducted research at Harvard University. Carl suffered from a rare bone marrow disease called myelodysplasia. "Look again at that dot.
Sun Orbit Everything’s orbiting something it seems. The Moon goes around the Earth, and the Earth orbits the Sun. But did you know that the Sun orbits the Milky Way galaxy? Astronomers have calculated that it takes the Sun 226 million years to completely orbit around the center of the Milky Way. In other words, that last time that the Sun was in its current position in space around the Milky Way, dinosaurs ruled the Earth. in fact, this Sun orbit has only happened 20.4 times since the Sun itself formed 4.6 billion years ago. Since the Sun is 26,000 light-years from the center of the Milky Way, it has to travel at an astonishing speed of 782,000 km/hour in a circular orbit around the Milky Way center. It’s estimated that the Sun will continue fusing hydrogen for another 7 billon years or so. Are you interested in more articles about the Sun? Here’s an article that describes the process astronomers used to determine the orbit around the Milky Way. References:NASA Imagine the Universe! Related

Speed of the Milky Way in Space As we all know, a galaxy is a massive ensemble of hundreds of millions of stars. The galaxy where we live in today is called the Milky Way. The name itself came from the ancient Greek galaxies kyklos, or ring of milk, due to its faint milky appearance. Our Milky Way is a large spiral galaxy. Its diameter is at least 100,000 light-years, and may contain as many as 200 billions stars today. Ever since four hundred years ago the settlement that the Earth is moving about the sun, and one hundred and fifty years ago that the sun is moving about the center of the Galaxy, it shouldn't be surprising if we learned that the Galaxy is also moving. In 1928, an American astronomer Milton La Salle Humason found a galaxy that was receding at a speed of 3,800 km/s, and by 1936, when he observed the same galaxy again, he found it receding at a speed of 40,000 km/s. If our galaxy exerted a repulsive force, that force should be felt with the local groups, however it wasn't. Patricia Kong -- 1999
Watch an Interactive Time-Lapse of Earth's History From Space by Google, NASA and TIME Have you ever wanted to go back in time to see what the planet looked like in yesteryear? Today, Google working with TIME magazine, NASA and the U.S. Geological Survey (USGS) is releasing more than a quarter-century of images of Earth taken from satellites in space, all compiled for the first time ever into an awesome interactive time-lapse experience! Google believes “this is the most comprehensive picture of our changing planet ever made available to the public.” The time-lapse images were built from millions of satellite photographs consisting of trillions of pixels. These stunning images were collected during an ongoing joint mission between the USGS and NASA called Landstat. As the final step, Google worked with the CREATE Lab at Carnegie Mellon University, recipients of a Google Focused Research Award, to convert all these Earth images into a seamless, browsable HTML5 animation on Google’s Timelapse website. What do you think about the Earth time-lapse project?
60 milliards de planètes pourraient être habitables dans la Voie lactée Selon une nouvelle étude menée par des astronomes, les planètes orbitant autour de naine rouge et présentant une atmosphère nuageuse pourraient aussi être habitables. Ceci porte à quelque 60 milliards le nombre de planètes qui pourraient abriter de la vie dans notre galaxie, la Voie lactée. Alors que la quête de vie extraterrestre motive depuis des décennies de nombreux astronomes, on ne saura bientôt plus où donner de la tête pour la rechercher. Avez-vous déjà partagé cet article? Partager sur Facebook Partager sur Twitter Pour en arriver à cette conclusion, les chercheurs se sont concentrés sur l'étude de planètes orbitant autour d'étoiles appelées naines rouges. Des nuages rafraichissants Jusqu'ici, les spécialistes supposaient donc que chaque naine rouge abritait au moins une planète habitable, c'est-à-dire un objet se trouvant ni trop loin, ni trop près, ce qui autorise la présence d'eau à l'état liquide à sa surface.

MACS J0717- New Image Exposes Violent Collision of Galaxies - Physics-Astronomy Astrophysicists at the National Radio Astronomy Observatory (NRAO) have collected data from a variety of devices to generate a stunning compound image of crashing galaxy clusters mutually identified as MACS J0717. MACS J0717 is about 5.4 billion light years away from Earth in the Auriga constellation. The composite makes this the record well-studied galaxy cluster, and the photo was issued at the 224th Meeting of the American Astronomical Society. The background of this stunning image was taken by NASA’s Hubble Space Telescope and captures wavelength spectra covering near ultraviolet, visible, and near infrared. The blue light in the image characterizes x-ray wavelengths, captured by the Chandra X-Ray Observatory. Image Credit: Van Weeren, et al.; Bill Saxton, NRAO/AUI/NSF; NASA. The blue and red areas symbolize several of the most sensitive images ever collected by these instruments, and the radio waves exposed outcomes that were pretty amazing.
Sciences et Technologies : Pourquoi la conquête de l'espace profite à tous HISTOIRES DE SAVOIR - Jean-Luc Nothias rappelle que de nombreuses technologies de pointe sont dérivées d'innovations destinées dans un premier temps à l'aérospatiale. Photo prise depuis la navette Atlantis juste après la saisie du téléscope Hubble par le bras robotisé d'Atlantis. Crédit photos : NASA La conquête spatiale a déjà fait rêver de nombreuses générations d'hommes et de femmes. Et petit à petit, les humains colonisent l'espace. Il y a quarante ans, des hommes marchaient sur la Lune. Ainsi, les avancées technologiques réalisées pour conquérir l'espace ont envahi notre quotidien. Et ce n'est pas fini. Il y a un mois et demi, la fusée Ariane mettait en orbite les télescopes européens Herschel et Planck. Une démarche devenue une référence mondiale Un autre grand domaine ayant bénéficié des retombées du spatial est celui des matériaux. Mais l'une des retombées les plus spectaculaires de la conquête de l'espace, et la moins connue, est celle de l'alimentation.
