The Universe is Alive “Night, when words fade and things come alive. When the destructive analysis of day is done, and all that is truly important becomes whole and sound again.” -Antoine de Saint-Exupery When you look out into the Universe, what is it that you typically think of? Image credit: Wally Pacholka of The unchanging nature of the points of light in the sky? Image credit: Roth Ritter (Dark Atmospheres), of the double cluster in Perseus. Maybe you think deeper and farther than that. Image credit: Misti Mountain Observatory. I couldn’t fault you for thinking like this; from mankind’s point of view, the Universe — for all intents and purposes — doesn’t change at all as we view it from one night to the next. But does that really mean the Universe isn’t changing? Let me flip this around on you: how much does anything here on Earth — you, your surroundings, even an entire, vibrant city — change in half-a-millisecond? Not a whole lot, that’s for certain.

Une exoplanète en zone habitable? | Science Impression artistique du système planétaire entourant l'étoile HD 40307. Photo : ESO Trois nouvelles planètes ont été détectées autour d'une étoile située à 42 années-lumière du Soleil. L'une d'elles se trouverait même dans la zone habitable. Le chercheur Mikko Tuomi et ses collègues de l'Université Hertfordshire les ont observées à l'aide de l'instrument HARPS installé sur le télescope de 3,6 mètres à l'Observatoire de La Silla de l'Observatoire européen austral (ESO) au Chili. Les chercheurs estiment que la planète possède environ 7 fois la masse de la Terre et pourrait abriter de l'eau à l'état liquide. En juin 2008, trois premières planètes avaient été découvertes autour de cette étoile plus petite que le Soleil. Plus de détails à venir. À la mi-octobre, des chercheurs suisses de l'Observatoire de Genève avaient annoncé qu'ils avaient détecté une exoplanète orbitant autour de l'étoile Alpha du Centaure B, située à 4 années-lumière dans le système stellaire le plus proche de la Terre.

Dès lors, le monde entre dans une phase de développement fulgurante et inégalée dans l'histoire : en moins d'un demi-siècle, l'Homme parvient à envoyer le premier objet dans l'espace, et, dix ans plus tard, le premier homme. L'entrée du monde dans l'âge spatial s'est cependant faite dans un cadre historique particulier, qui a marqué les mémoires de plusieurs générations. 1. Figure 1 - Constantin Tsiolkovski, l'un des pères fondateurs de l'astronautique Bien avant les exploits concrets des années 50 et 60, Isaac Newton, au 17ème siècle, jette déjà les bases de l'astronautique dans son traité Principes mathématiques de philosophie naturelle. Mais ce n'est qu'après les deux guerres mondiales que les travaux des scientifiques du début du siècle vont trouver leur utilité, et que les auteurs d'anticipation vont voir leurs rêves se réaliser. 2. 3.

Science Space Photo of the Day | Wired Science When the lamp is shattered, The light in the dust lies dead. When the cloud is scattered, The rainbow's glory is shed. These words, which open Shelley’s poem "When the Lamp is Shattered," employ visions of nature to symbolize life in decay and rebirth. It's as if he had somehow foreseen the creation of this new Gemini Legacy image, and penned a caption for it. What Gemini has captured is nothing short of poetry in motion: the colorful and dramatic tale of a life-and-death struggle between two galaxies interacting. Polar-ring galaxies are peculiar objects. Models of how polar-ring galaxies form offer two general formation scenarios: 1) a piercing merger between two galaxies aligned roughly at right angles, or 2) when the host galaxy tidally strips material from a passing gas-rich spiral and strews it into a ring. Born of Violence NGC 660’s polar ring resolves into hundreds of objects, a considerable part of which are blue and red supergiant stars. Weighing the Evidence Life from Death?

The Planet's Most Powerful Digital Camera Captures Its First Images of the Universe - Megan Garber The device could help astronomers figure out why the expansion of the universe is accelerating. Zoomed-in image from the Dark Energy Camera of the center of the globular star cluster 47 Tucanae, which lies about 17,000 light years from Earth (Dark Energy Survey Collaboration) The Dark Energy Camera is the world's most powerful digital camera. About the size of a phone booth and boasting 570 megapixels, the device took eight years to construct -- by astronomers, technicians, and engineers collaborating across three continents -- and is currently mounted to the Blanco telescope in Chile. From that perch, it is able to observe light from over 100,000 galaxies. Galaxies that are up to 8 billion light years away. Again: 8 billion light years away. That light isn't just mind-bogglingly ancient. Last week, the Dark Energy Camera captured its first light, capturing images of matter from across the universe.

Image Gallery Martian Rock and Dust Filling Studied with Laser and Camera Scientists used the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity Mars rover in June 2014 to examine a Martian rock "shell" about one inch (two to three centimeters) across, embedded in fine-grained bedrock and with a dust-filled hollow interior. This graphic combines an image of the target, called "Winnipesaukee," with spectrographic results from using ChemCam's laser on a row of points including the rock, the matrix around it and the material filling it. The image merges a high-resolution, black-and-white image from ChemCam's remote micro-imager and a color image form the telephoto-lens camera of Curiosity's Mast Camera (Mastcam). Analysis of spectra from the bedrock (black circles) identified high abundances of oxides of silicon, aluminum and sodium, typical of a feldspathic composition. Scientists are considering multiple hypotheses for how this hollow feature formed.

The Elegant Universe: Series ... The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination. This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything." Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. S. BRIAN GREENE:The atmosphere was electric. S.
