Huge Defunct Satellite to Plunge to Earth Soon, NASA Says
For the latest news about NASA's UARS spacecraft fall, visit: Falling NASA Satellite: Complete Coverage of UARS Spacecraft's Fiery Demise. Heads up! That's the word from NASA today (Sept. 7) given the impending re-entry of a 6.5-ton satellite through Earth's atmosphere. The huge Upper Atmosphere Research Satellite (UARS) is expected to re-enter Earth's atmosphere in an uncontrolled fall in late September or early October. Much of the spacecraft is expected to burn up during re-entry, but some pieces are expected to make it intact to the ground, NASA officials said.
Radio telescopes capture best-ever snapshot of black hole jets
An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany. The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made. The study will appear in the June issue of Astronomy and Astrophysics and is available online.
Milan’s Vertical Forest
Wednesday, 12 October 2011 GreenMuze Staff Milan’s Vertical Forest from Stefan Boeri Architects. The Bosco Verticale (Vertical Forest) will be the greenest building in Milan when completed, which is one of Europe’s most polluted cities. Designed by Stefan Boeri Architects, as part of their BioMilano vision to incorporate 60 abandoned farms into a greenbelt surrounding the city. The Bosco Verticale building has a green façade planted with dense forest systems to provide a building microclimate and to filter out polluting dust particles. The living bio-canopy also absorbs CO2, oxygenates the air, moderates extreme temperatures and lowers noise pollution, providing aesthetic beauty and lowering living costs.
Douglas Adams Quotes
He attacked everything in life with a mix of extraordinary genius and naive incompetence, and it was often difficult to tell which was which. Douglas Adams He hoped and prayed that there wasn't an afterlife. Then he realized there was a contradiction involved here and merely hoped that there wasn't an afterlife. Humans are not proud of their ancestors, and rarely invite them round to dinner.
Astronauts May Evacuate Space Station in November, NASA Says

Philosophy
.. My purpose therefore is, to try if I can discover what those principles are, which have introduced all that doubtfulness and uncertainty, those absurdities and contradictions into the several sects of philosophy; insomuch that the wisest men have thought our ignorance incurable, conceiving it to arise from the natural dullness and limitation of our faculties. (George Berkeley) Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science. (Charles Darwin, Introduction to The Descent of Man, 1871) Hi Everyone (December, 2009)
Pax Americana and the Weaponization of Space
Star Wars is no longer science fiction. The prospect of Earth being ruled from space is no longer science-fiction. The dream of the original Dr. Strangelove, Wernher von Braun (from Nazi rocket-scientist to NASA director) has survived every US administration since WW2 and is coming to life.
Video Courses on Academic Earth
Astronomers use tools like telescopes, cameras and spectrographs to study interactions between materials and energy within the universe. These scientists learn about galaxies, solar systems, planets and stars through careful observation and measurement recording. Astronomers also refer to natural sciences and mathematics to form and test theories. An integral part of a student’s astronomy experience is the quality of equipment and facilities they have access to. Astronomy departments at the University of Hawaii at Manoa, Harvard University and the University of Tokyo give students access to some of the best observatories in the world.
