NASA Earth Observatory : Home Earth Earth is the third planet from the Sun. It is the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world or the Blue Planet. Earth formed approximately 4.54 billion years ago, and life appeared on its surface within its first billion years. Earth's biosphere then significantly altered the atmospheric and other basic physical conditions, which enabled the proliferation of organisms as well as the formation of the ozone layer, which together with Earth's magnetic field blocked harmful solar radiation, and permitted formerly ocean-confined life to move safely to land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist. Name and etymology In general English usage, the name earth can be capitalized or spelled in lowercase interchangeably, either when used absolutely or prefixed with "the" (i.e. Heat
Earth Earth Earth is a complex, dynamic system we do not yet fully understand. The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. This is a composite image of the North African Continent. A major component of NASA’s Earth Science Division is a coordinated series of satellite and airborne missions for long-term global observations of the land surface, biosphere, solid Earth, atmosphere, and oceans. The Foundational missions are those missions in development at the time the decadal survey was published and include CLARREO, Aquarius, Suomi National Polar-orbiting Partnership (S-NPP), Landsat Data Continuity Mission (LDCM), and Global Precipitation Measurement (GPM).

The Green PostBox : Développement durable Ca ressemble à un titre de campagne, ou mieux, à une diatribe d'un candidat de front de gauche (...), mais ça n'est pas de la politique, en tout cas, pas comme la politique se fait entendre en ce moment. Samedi 31 mars, ce samedi, l’opération "Tous Candidats" s'inscrit dans une grande journée de mobilisation inter-associative : Greenpeace pour la campagne "Libérons l'énergie" et l’initiative "Libérons les élections", lancée par plus d’une trentaine d'organisations de la société civile, se joindront ainsi aux milliers de colibris pour la libération du pouvoir citoyen ! Mais aussi, ce 31 mars, la campagne « Tous candidats » s'appuie sur la plateforme Inside-Out pour la plus grande opération de cette initiative artistique jamais réalisée. Des milliers de portraits seront affichés dans 40 villes de France pour donner un visage à tous ceux qui souhaitent une véritable transformation de notre société. Nous on y sera... et vous ?
on reserve Plate Tectonics The Tectonic Globe™ The Plate Tectonic Globe™ The Plate Tectonic Globe™ is a globe unlike any other currently on the market. Its unique hand-crafted design illustrates clearly and accurately Earth's crustal tectonic features in vivid relief. The Plate Tectonic Globe™ captures the essence of Earth's dynamic character by depicting tectonic plate boundaries at mid-ocean ridges, subduction zones, and continental collision zones. Other distinguishing characteristics of The Plate Tectonic Globe™ include raised and indented continental shelves, terrestrial and sea-floor topography, major transform faults, island chains, island arcs, and the relative thickness of continental and oceanic crust - all engineered in hand-sculpted relief. Aside from its unique aesthetic qualities, the tactility of our Plate Tectonic Globe makes it ideal for developing an understanding of Earth's tectonic nature by making it fun to explore the surface of the planet in a hands-on, minds-on way.
Extreme Weather Photo Contest Winners | Precipitation Measurement Missions Thank you to everyone who submitted photos to the first installment of our GPM Extreme Weather Photo Competition. We loved all of your entries and thoroughly appreciate your participation! The GPM Photo Competition Committee is happy to announce our top 5 picks. We’ll be sending the submitters NASA bags and GPM stickers. Please stay tuned for additional contests and activities. Ormond Shelf, by Jason Weingart Date and Location: May 15, 2012 Ormond Beach, Florida How this Photo Was Taken: “I'm a photography student at the University of Central Florida. I have shot many storms from the same spot this photo was taken, and I almost drove by to get a different vantage point, but something told me to just stop at my spot. The storm actually pushed back on shore as it moved south, and then became strong enough for tornado warnings on three separate occasions. Fun Fact: A shelf cloud is a type of arcus cloud with a wedge shape. About Photographer Jason Weingart: Thunderstorm, by Grant Petty
