Spy agency gives NASA two spare Hubbles - Achenblog Posted at 09:21 AM ET, 06/05/2012 Jun 05, 2012 01:21 PM EDT TheWashingtonPost What a country! The Hubble being deployed. At The Atlantic, Alexis Madrigal poses a number of questions about this rather startling technology transfer, including: “....if the DOD didn’t need these two birds, which are both better than any civilian telescope, what *do* they have? “....how did this happen? Here’s my semi-informed effort to answer Alexis. I’m told by a government engineer with knowledge of the new instruments that they’re “a successful part of an otherwise failed program on the NRO side.” As for what they else the military/intelligence agencies have up there, well, they have more of these KH-11 Kennan spy satellites that use Hubble-class mirrors. As for how this transfer came about, the answer is, with much effort on the part of NRO and NASA folks. So the story that broke yesterday was really a controlled roll-out by NASA of something that’s been in the works for nearly a year and a half.
EZB-Entscheidung: Draghi gibt Banken Zucker – und droht mit der Peitsche - Konjunktur Soziale Netzwerke dauerhaft einschalten BratislavaDie Banken in der Euro-Zone können sich noch mindestens ein Jahr lang unbegrenzt Geld bei der Europäischen Zentralbank (EZB) leihen. Diese Regelung werde mindestens bis zum 9. Bei ihrer Sitzung in Bratislava senkte die Europäische Zentralbank ihren Schlüsselzins von 0,75 auf das Rekordtief von 0,5 Prozent. Billiges Geld: Schlechte Zeiten für Sparer Warum macht die EZB das Geld im Euroraum noch billiger? Die EZB könnte die Banken zu einer stärkeren Kreditvergabe animieren, indem sie künftig eine Art Strafgebühr zahlen müssen, wenn sie Geld bei der Zentralbank parken. Banken können Geld bei der EZB parken, wofür sie in normalen Zeiten Zinsen bekommen. Stimmen zum Zinsentscheid der EZB Marcel Fratzscher (Präsident des DIW-Instituts):„Man sollte sich nicht an die Hoffnung klammern, dass die EZB-Entscheidung die Finanzierungsbedingungen in den Krisenländern deutlich verbessern wird.

NASA new discovery could revolutionize search for life in the universe Source: NASAblueshift via Flickr Caption: NASA new discovery, Kepler-22b (an artist's rendition) A new discovery from NASA could be the best candidate yet for an Earth-like life-bearing world beyond our own solar system, and it's only 600 light-years from our home planet. NASA’s new discovery, named Kepler-22b, shares some crucial similarities with Earth, leading scientists to believe that this newly-discovered planet could be the best chance yet for supporting life. Kepler-22b was spotted by NASA’s Kepler space telescope in its position outside our solar system. “It’s right in the middle of the habitable zone,” said Natalie Batahla, a Kepler scientist. A habitable zone is comprised of the space around a star that life-supporting liquid water could possibly exist in. What excites scientists and researchers beyond Kepler-22b’s position within a Goldilocks zone, are the similarities the planet shares with our own.
Field Guide to X-ray Astronomy :: Stellar Evolution Stellar Evolution The Milky Way Galaxy contains several hundred billion stars of all ages, sizes and masses. One of the central quests of astronomy is to understand how these star form, shine for billions of years, and eventually fade quietly into the dark as white dwarf, or go out with a bang as supernovas. Chandra and other X-ray telescopes focus on the high-energy action of this drama - sudden outbursts on the turbulent surfaces of stars, gale-force outflows of gas from hot, luminous stars, and awesome shock waves generated by supernova explosions. Overview of Stellar Evolution A Star is Born A star is born when a cloud of gas and dust collapses to the point where the material in the center of the clump is so dense and hot that the nuclear fusion of hydrogen nuclei into helium nuclei can occur. Hydrogen Burning Core (Main Sequence) Fusion of hydrogen into helium in the core of star can sustain a star such as the Sun for billions of years. Red Giants. Mass Matters.
Space smells like seared steak, hot metal, astronauts report Astronauts who have gone on spacewalks consistently speak of space's extraordinarily peculiar odor. Skip to next paragraph Subscribe Today to the Monitor Click Here for your FREE 30 DAYS ofThe Christian Science MonitorWeekly Digital Edition Astronaut Greg Chamitoff, aboard the International Space Station 220 miles above Earth, is taking your questions. They can't smell it while they're actually bobbing in it, because the interiors of their space suits just smell plastic-y. Fugitives from the near-vacuum — probably atomic oxygen, among other things — the clinging particles have the acrid aroma of seared steak, hot metal and welding fumes. "It's like something I haven't ever smelled before, but I'll never forget it," NASA astronaut Kevin Ford said from orbit in 2009. But astronauts don't dislike the sharp smell of space, necessarily. The interior of the International Space Station smells a little more mundane.
PlanetInAction.com - The planet is your playground Big Bang Was Actually a Phase Change: New Theory How did the universe begin? The Big Bang is traditionally envisioned as the moment when an infinitely dense bundle of energy suddenly burst outward, expanding in three spatial directions and gradually cooling down as it did so. Now, a team of physicists says the Big Bang should be modeled as a phase change: the moment when an amorphous, formless universe analogous to liquid water cooled and suddenly crystallized to form four-dimensional space-time, analogous to ice. In the new study, lead author James Quach and colleagues at the University of Melbourne in Australia say the hypothesis can be tested by looking for defects that would have formed in the structure of space-time when the universe crystallized. "Think of the early universe as being like a liquid," Quach said in a statement. If they exist, these cracks should be detectable, the researchers said, because light and other particles would bend or reflect off of them as they trek across the cosmos.
Around the Solar System - In Focus Robotic probes launched by NASA, the European Space Agency (ESA), and others are gathering information all across the solar system. We currently have spacecraft in orbit around the Sun, Mercury, Venus, Earth, Mars, and Saturn, and two operational rovers on Mars. Several others are on their way to smaller bodies, and a few are heading out of the solar system entirely. Although the Space Shuttle no longer flies, astronauts are still at work aboard the International Space Station, performing experiments and sending back amazing photos. With all these eyes in the sky, I'd like to take another opportunity to put together a recent photo album of our solar system -- a set of family portraits, of sorts -- as seen by our astronauts and mechanical emissaries.

San Rafael boy gets letter from Neil Armstrong shortly before astronaut's death By Janis Mara Marin Independent Journal Posted: 08/28/2012 07:11:26 AM PDT0 Comments|Updated: about a year ago As the world mourns Neil Armstrong, the first astronaut to walk on the moon, an 11-year-old San Rafael boy has a special reason to miss him -- and a message from the astronaut he will always treasure. "Sometimes when I look up at the moon, I wonder if my mom and dad are watching me," wrote Max Boddington, whose mother died in 2005 and his father in 2008. He ended his essay, written two years before Armstrong's death on Saturday: "My dream is to meet Neil Armstrong, the world's Number One space hero." The boy's adoptive mother, Janet Boddington, kept the essay and submitted it to the 2012 Marin County Fair. On Aug. 1 the astronaut, who commanded the Apollo 11 moon landing on July 20, 1969, emailed her back: "Thanks for sharing Max's essay with me," Armstrong wrote. When his mom showed him the email, "I jumped up and down. "We were all just overwhelmed that Mr.
Creating a Learning Environment for Young Children The following is an excerpt from Teaching Our Youngest. Introduction What do effective preschool teachers and child-care providers do? What does a classroom that can enhance learning look like? Effective preschool classrooms are places where children feel well cared for and safe. Young children need teachers who welcome all children to their classrooms, including children from various cultures, whose first language is not English and children who have disabilities. Effective preschool teachers and child care providers: Know when children can figure out new ideas and concepts on their own and when it is important to explain things to them step-by-step. A Classroom to Enhance Learning Ms. She uses cupboards, screens, and tables to divide her classroom into children's work areas. Most of the books on the bookcases come from the classroom library, but others are part of a revolving collection of books that Ms.
Goddard Multimedia Item 10918 - Galactic Lobes Gamma rays radiate from the Milky Way's center, but where do they come from? Scientists have discovered gigantic structures 25,000 light-years tall ballooning above and below the Milky Way. Within each curved lobe, extremely energetic electrons of unknown origin interact with lower-energy light to generate the gamma rays that define these bubbles.

Life on Earth under threat from CO2 levels, say scientists - Climate Change - Environment Current CO2 emissions are currently tracking on the highest trajectory envisaged by climate scientists. That means if nothing is done to reduce emissions significantly over the coming decades, over half of common plants and one-third of the animals could see a serious decline, the study concluded. Scientists came to the assessment by estimating the current and future geographical ranges of nearly 50,000 widespread and common species to see how rising temperatures are likely to affect their territorial limits as defined by the sort of climate they are adapted to live in. Plants, amphibians such as frogs and toads, and reptiles such as lizards are the groups that are likely to suffer the most from a changing climate because of their relative vulnerability to rising temperatures and inability to move rapidly from one territory to another, the study found.
Night-Shining Clouds Get Glow from Meteor Smoke Rare and mysterious clouds that are so bright they can be seen at night have mystified people since they were first observed more than a century ago, but scientists have now discovered a key cosmic ingredient for these night-shining clouds: "smoke" from meteors as they burn up in the Earth's atmosphere. Blue-white clouds that eerily glow in the twilight sky are called noctilucent clouds, or NLCs. They typically form about 50 to 53 miles (80 and 85 kilometers) above ground in the atmosphere, at altitudes so high that they reflect light even after the sun has slipped below the horizon. PHOTOS: Transit of Venus Photos From Our Readers In a new study, scientists found that noctilucent clouds have an extraterrestrial link. "We've detected bits of 'meteor smoke' imbedded in noctilucent clouds," James Russell, an atmospheric scientist at Hampton University in Hampton, Virginia, said in a statement.
