Anexo:Objetos Messier Los objetos Messier son un grupo de objetos astronómicos catalogados por el astrónomo francés Charles Messier en su Catalogue des Nébuleuses et des Amas d'Étoiles (Catálogo de Nebulosas y Cúmulos Estelares), que se publicó originalmente en 1771 y cuya última edición, basada en observaciones de Messier, se realizó en 1966.[1] Messier centraba su interés en encontrar cometas por lo que creó una lista de objetos descubiertos por él mismo que parecían ser cometas pero que no lo eran. La compilación de esa lista, en colaboración con su asistente Pierre Méchain, se conoce como «catálogo Messier». Es una de las listas más famosas de objetos astronómicos, y muchos de los objetos incluidos en ella siguen siendo referenciados por su número Messier.[2] La primera edición del catálogo incluyó 45 objetos; luego Messier completó la lista totalizando 103 objetos. No obstante, otros astrónomos usaron las notas de Messier para terminar la lista con 110 objetos. Objetos Messier[editar] Véase también[editar]
Circulating Fish Tank and Plant Pot by Sheng-Zhe Feng and Ling-Yuan Chou One Pot, Two Lives No drugs! Only fishes and plants. Not weed! Thought I bet it’d be extra cool if-no! This is a planter and a fishtank. Let us discuss something – the size. Using this system of cycling materials keeps the fish poo from staying in the water long enough to turn it acidic. Benefits! The soil remains humid, extending the watering period by about one week.The product’s middle layer is the filter layer, which accumulates fertilizer as the nutrient for outdoor pot plant. So… I’m also adding this to my gift list. Course Director: Dr. Designers: Sheng-Zhe Feng and Ling-Yuan Chou
Galaxy Zoo SDSS-III Grupo Local Mapa 3D del Grupo Local. Otro mapa 3D del Grupo Local. Se denomina Grupo Local al grupo de galaxias en el que se encuentra la nuestra, la Vía Láctea. Está dominado por tres galaxias espirales gigantes, Andrómeda, la Vía Láctea y la Galaxia del Triángulo. El resto de galaxias, unas 30, son más pequeñas; muchas de ellas son galaxias satélite de una de las mayores. Las galaxias libres giran en torno al centro de masas del grupo, situado entre Andrómeda y la Vía Láctea. Dentro del Grupo Local, se conocen tres sistemas dominados por galaxias masivas actuando como centros de gravedad, y varias galaxias actuando como satélites: El futuro del Grupo Local[editar] Se ha observado que Andrómeda y nuestra galaxia se acercan rápidamente a una velocidad de unos 500.000 km/h, lo que plantea que pueda producirse una colisión entre ambas dentro de unos 3.000 a 5.000 millones de años, según la masa que tengan estas galaxias.

The Milky Way Project Sloan Digital Sky Survey ¿Por qué E=mc2?: ¿y por qué debería importarnos? - Brian Cox, Jeff Forshaw ¿Qué significa en realidad E = mc2? Brian Cox y Jeff Forshaw emprenden un viaje hasta las fronteras de la ciencia del siglo xxi para descubrir qué se esconde detrás de la secuencia de símbolos que conforman la ecuación más famosa de Einstein. Explicando y simplificando las nociones de energía, masa y luz, demuestran que esta ecuación contiene la estructura misma de la naturaleza. «Si no eres físico y quieres comprendera Einstein y su teoría de la relatividad, deberías leer este libro.» «Un libro que nos muestra lo hermoso y complejo que es nuestro universo.»
Weird Aquariums: One Pot, Two Lives - Okeanos Aquascaping Posted by Dabney B. on Tuesday, May 29th, 2012 Image: tfhmagazine.com Out in the ocean and rivers there are a million different components working together to create a harmonious ecosystem for fish. Aquarists can replicate those conditions as best they can, but there will always be a few problems that hobbyists run into. How are these factors regulated in the wild? Image: yankodesign.com This harmonious relationship is the guiding principle behind One Pot, Two Lives. When you pour water onto the plant it trickles down through the soil and gets sucked up by the plant’s roots. But that’s not all. Now, don’t get me wrong, there’s nothing particularly revolutionary about this tank.
The Venus Project Astrophysics Astrophysics People have gazed at the stars, given them names, and observed their changes for thousands of years. NASA joined the ancient pursuit of knowledge of our universe comparatively recently. Goals The science goals of Astrophysics are breathtaking: we seek to understand the universe and our place in it. NASA’s goal in Astrophysics is to “Discover how the universe works, explore how the universe began and developed into its present form, and search for Earth-like planets.” Current Programs Astrophysics comprises of three focused and two cross-cutting programs. Physics of the Cosmos Cosmic Origins Exoplanet Exploration Astrophysics Explorer Program Astrophysics Research Current Missions The Astrophysics current missions include three of the Great Observatories originally planned in the 1980’s and launched over the past 24 years. Near Future The near future will be dominated by several missions.
Homemade Tattoos First he showed us how to stuff a mouse. Now Andreas is back with a needle, ink, and some beer. Photos: Trippe & Trolf Yeah, bad tattoos are basically a bummer, right? But they're also pretty much a rite of passage for bored and disenfranchised-feeling teenagers the world over. At least it was for about 95% of the people I know. It's easy-anyone can do it (even teenagers, who, according to recent scientific tests, don't even have fully functional brains). Here's what you'll need: 1) Sewing needles, not too big and not too little. To start with, assemble all your supplies on your work surface. Wait, on second thought, let's include one more thing in the photo: Being neat isn't required, but my OCD makes me have to arrange everything at right angles to everything else. Ask yourself before starting: Do I know this person I'm going to tattoo? There will be a little blood, so it's best to be cautious. Oh man, I forgot one incredibly important component to successful home tattooing: music.
