POPSSun NASA's Solar Dynamics Observatory is beaming back stunning new images of the sun, revealing our own star as never seen before. Even veteran solar physicists say they are amazed by the data. Movies and images may be found in today's story from Science@NASA. FULL STORY at http://science.nasa.gov/science-news/science-at-nasa/2010/21apr_firstlight/

POPSTableau De L'Histoire Universelle depuis la Creation jusqu'a ce jour This is a fold-out print depicting all of human history from the time of creation (4693 BC = Adam & Eve; the great flood = 3300 BC) up to the date of publication (1858 by Eug. Pick, Paris). Vignettes of historically significant people, places and buildings etc are arranged along the borders. This audacious document mirrors the style of a similar graphical print by Colton from 1842 and is in the same ballpark as an 1836 chart by Emma Willard (see here). The designer has employed something of a metaphorical display choice: civilisations are presented as a series of rivers -- the widths likely imply the comparative population level of each group versus the world's population -- which 'flow' down through history.

POPSWater on Titan Titan, Saturn's largest moon, has captivated scientists because of its many similarities to Earth. Scientists have theorized for 20 years that Titan's cold surface hosts seas or lakes of liquid hydrocarbons, making it the only other planetary body besides Earth believed to have liquid on its surface. While data from Cassini have not indicated any vast seas, they have revealed what appeared to be large lakes near Titan's north and south poles.

POPSSandtrapped Rover Makes a Big Discovery "Spirit had to get stuck to make its next discovery," says Arvidson. As the rover tried to break free, its wheels began to churn up the soil, uncovering sulfates underneath. "Sulfates are minerals just beneath the surface that shout to us that they were formed in steam vents, since steam has sulfur in it. Steam is associated with hydrothermal activity – evidence of water-charged explosive volcanism. Such areas could have once supported life." "And most amazingly, the boundary between the sulfate-rich soil and the soil with just the generic concentration of sulfates runs right down the middle of the stranded rover. Spirit is lodged on the edge of a crater -- sitting astride the boundary!"

POPSCuriosity, the new Mars Rover The small, car-sized rover will ramble about on the rocky surface, gizmos at full tilt, not only brushing dust off rocks but also vaporizing them with a laser beam, gathering samples to analyze on the spot, taking high resolution photographs, and more.

POPSWater on the moon These images show a very young lunar crater on the side of the moon that faces away from Earth, as viewed by NASA's Moon Mineralogy Mapper on the Indian Space Research Organization's Chandrayaan-1 spacecraft. On the left is an image showing brightness at shorter infrared wavelengths. On the right, the distribution of water-rich minerals (light blue) is shown around a small crater. Both water- and hydroxyl-rich materials were found to be associated with material ejected from the crater.

POPSOmega Centauri Colorful Stars Galore Inside Globular Star Cluster Omega Centauri NASA's Hubble Space Telescope snapped this panoramic view of a colorful assortment of 100,000 stars residing in the crowded core of a giant star cluster. The image reveals a small region inside the massive globular cluster Omega Centauri, which boasts nearly 10 million stars.

POPSSpace Station Room With a View The crew of the International Space Station (ISS) is about to get a new "eye-pod." The Tranquility node headed for the space station early in 2010 will feature a viewing dome unlike any other window ever flown in space. The dome, called the Cupola, is literally studded with windows for observing Earth, space, and the marvelous expanse of the ISS itself.

POPSthe Majestic Sombrero Galaxy Hubble Space Telescope has trained its razor-sharp eye on one of the universe's most stately and photogenic galaxies, the Sombrero galaxy, Messier 104 (M104). The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy. As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat. At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 28 million light-years from Earth.

POPSDe essentie van Web2.0 De essentie van Web2.0 is het faciliteren van online samenwerking (collaboration) tussen verschillende gebruikers en het creëren, bewerken en delen van content. YouTube, Flickr, Facebook en Wikipedia zijn hiervan de bekendste voorbeelden. Maar Web2.0 is breder dan alleen deze sociale platforms. Shopping 2.0, Intranet 2.0, Banking 2.0, Health2.0, … In allerlei vormen via een breed scala aan kanalen wordt het delen van content ondersteund door online technologie. Dat hiermee in een basale behoefte wordt voorzien, blijkt wel uit het massale gebruik ervan (zie figuur).

POPSFlag of Earth The flag was designed by James Cadle. Prior to the US landing on the moon, there was hope a flag for humanity, rather than the American flag, would be erected on the moon. Some hoped the UN flag would fly, but that never happened. At the Flag of Earth website there are templates for printing them out or purchasing ready-to-fly sown ones.

It was here that a rare photograph by celebrated contemporary artist Cindy Sherman sold for over $900,000--three times Christie's asking price. In "Untitled Film Still #13," Sherman poses as a librarian, gazing beyond the shelves of books that surround her.

POPSWater on Mars A color-enhanced image of the delta in Jezero Crater, which once held a lake. Researchers led by CRISM team member and Brown graduate student Bethany Ehlmann report that ancient rivers ferried clay-like minerals (shown in green) into the lake, forming the delta. Clays tend to trap and preserve organic matter, making the delta a good place to look for signs of ancient life.

POPSVoyager 2 Finds Lopsided Solar System Still transmitting, the three-decade-old craft encounters turbulence in solar wind. Hurtling through space 31 years after its launch, the Voyager 2 spacecraft has sent back the most detailed view yet of the shock wave that marks the thinning of the solar wind, the charged particles streaming from the sun. That would mean they have exited the solar system and entered the interstellar medium. NASA engineers estimate that both probes' plutonium power packs have the potential to keep them broadcasting data until 2025. If we're lucky, Jokippi says, they'll let us know what they find.
