*******www.themorningstarr******/2010/03/05/giant-ufo-filmed-above-china/ Extraordinary footage of a supposed pyramid shaped alien spacecraft has surfaced. The video is reported to have been shot above the Chinese city of Xi'an on 28th January this year. The film has been studied by Chinese ufologists who are certain the video is genuine and not clever CGI trickery. Ufologists around the internet have been hailing the video as the clearest, definitive proof that aliens are visiting our planet and many believe we are on the brink of making first contact with people from another world. Brilliant.

Transcript by Newsy. BY STEVEN SPARKMAN You're watching multisource science news analysis from Newsy. Don’t stare at the Sun, let NASA do it for you! For the first time, NASA scientists can view the entire surface of the Sun at once, thanks to the two STEREO probes. We’ll let New Scientist show you how it’s done. “Over the last four years, the two spacecraft have slowly made their way along Earth’s orbit, with STEREO A advancing ahead, and STEREO B falling behind. As they’ve separated, our view of the Sun has increased. … Now STEREO A and B are almost exactly opposite each other, and for the first time in human history we have a view of the entire Sun.” Scientists are studying the atmosphere of the Sun, specifically eruptions of charged matter called Coronal Mass Ejections, or CMEs. CMEs are like plasma volcanoes, and can interrupt GPS systems and satellites around Earth. Big CMEs could even knock out whole power grids. The Australian explains how the new 360 degree view can help scientists predict space weather. (Video source: NASA STEREO Mission) “Now scientists will be able to detect Earth-bound CMEs as soon as they leave the Sun's surface, giving crucial time to prepare. … With sufficient warning, satellites can be turned around so their shielding faces the eruption, or switched to a lower voltage, and power can be rerouted from parts of electricity grids.” The full view of the Sun will last for eight years, until the probes orbit back toward Earth. The time will allow scientists to test some longstanding theories about the Sun’s behavior that, a blogger for Discover Magazine explains, they just couldn’t test without a full view. “The Sun is not a solid object; it’s a seething, writhing ball of plasma (ionized gas). Something might happen on the far side and it would take a week or more for it to rotate into view, and by then it will have evolved or possibly even disappeared entirely! … Scientifically, this is critical for understanding the Sun.” The timing of the probes couldn’t be better. The Sun’s activity changes from year to year, and a writer for Sky and Telescope points out observations are about to get much more exciting. “The Sun is just rousing itself from a deep and prolonged hibernation in its 11-year-long activity cycle. But once activity ramps up in a year or two, CMEs will occur at least every couple of weeks.” So what you think of the stereophonic sun spotter? Let your thoughts shine in our comments section.

BY MATTHEW HIBBARD You're watching multisource science news analysis from Newsy Space shuttle Discovery touched down for the last time Wednesday, wrapping up another chapter of U.S. space travel. NASA’s oldest and most-flown spacecraft ends its career with 148 million miles and 365 days spent in space. As the shuttles start to roll into retirement, it’s hard for astronauts to keep back the emotions. Current astronauts of STS-133 mission tell Orlando’s WFTV, the Discovery will be hard to leave behind. “After we land, that will be the time where we’ll reflect. I suspect, seated on the runway, I’ll be sitting in my seat when we do the last switch throw and it’s time for me to get out and I don’t think I’m going to want leave my seat.” With the Discovery heading for retirement, NASA’s future plans for space exploration are still up in the air. Former NASA Astronaut Bob Springer, who flew on the shuttle in 1989, tells CNN how NASA needs to rediscover its identity before it can move forward. BOB SPRINGER: “This is a difficult time, you know, and it’s still a little bit incomprehensible to me that we’re shutting down one program before we have another viable program online. Where of course, NASA is struggling to reidentify itself and find out exactly where NASA want to go in the future.” The future of where the shuttles will go is also in the dark. A widespread assumption is they’ll end up in the Smithsonian's National Air and Space Museum near Virginia, but museum spokesperson Brian Mulen told MSNBC, NASA has yet to make a decision. And while the shuttle may be best known for its space flights, it also provided paychecks. A writer for The New York Times says the end of the shuttle program is stirring up mixed feelings. “[This] a bitter pill for the thousands of men and women who have worked on the shuttle fleet over the past three decades, who now face layoffs and the prospect of seeing Discovery, Endeavour and Atlantis — the world’s most sophisticated spacecraft — turned into museum displays. After the next two space shuttles are flown, American astronauts will have to hitch rides to the space station on Russian Soyuz capsules.

BY STEVEN SPARKMAN ANCHOR CHRISTINA HARTMAN You're watching multisource science news analysis from Newsy After a trip that’s covered nearly five billion miles, NASA’s Messenger probe is finally ready to start its mission. It’s arrived at the planet Mercury, beginning a years’ study to shed light on the sunniest planet. The Baltimore Sun has more. “Fifteen years of planning and 6 1/2 years of maneuvering in space will all come down to the crunch Thursday evening as mission managers in Maryland try to slip NASA's Messenger spacecraft into orbit around Mercury. The braking maneuver, playing out 96 million miles from Earth, will have to slow the desk-sized planetary probe by 1,929 mph and ease it into a polar orbit around the planet closest to the sun.” Getting to the Mercury wasn’t easy. The tiny planet moves about 65,000 mph faster than Earth. Instead of sending Messenger up with tons of fuel, NASA engineers picked up gravity boosts from the Earth, the Moon, Venus, and Mercury itself to get it up to speed. Now the fun begins. The probe will make highly elliptical sweeps around Mercury’s poles, then zip back out again. Hanging out in Mercury’s shadow for a while will allow the instruments to cool off, then it’s back in again every 12 hours. That’s over 700 orbits, with all of Messenger’s sensors firing. (Video source: NASA) Though Mercury is relatively close by, this will be the first time scientists have gotten a detailed look at it. The planet is kind of an oddity: it’s denser than the other rocky planets and has a gas trail like a comet. As UANews explains, it’s also unusually active. “One of the mysteries scientists are hoping to solve with the MESSENGER mission surrounds Mercury's magnetic field. At a diameter only slightly larger than that of the moon ... Mercury should have solidified to the core. However, the presence of a magnetic field suggests the planet's innards are partially molten.” NASA’s other probes have been shelling out data on planets in other solar systems, but astronomers still don’t know all the ins and outs of how rocky planets form. One of the researchers told Space**** that’s why studying Mercury is so important. “Discovering more about this searing hot, rocky sibling of Earth could shed light on how our solar system formed, and how alien planets coalesced around faraway stars... ‘Many exoplanets discovered to date are as close or closer than Mercury is to our host star...’ ” After a warm-up to get its sensors online, Messenger is expected to start sending back data in April. That means we could be just weeks away from finally answering the question, “Is there mercury on Mercury?” 'Like' Newsy on Facebook for updates in your news feed Get more multisource video news analysis from Newsy

BY STEVEN SPARKMAN You're watching multisource science video news analysis from Newsy. The little planet that isn’t just keeps churning out new surprises. New research on Pluto’s atmosphere shows the dwarf planet is way more dynamic than previously thought. Space**** reports the newest finds. “Poisonous carbon monoxide gas has been discovered in the atmosphere of the dwarf planet Pluto, after a worldwide search that lasted nearly two decades, according to a new study that also detected the planet's atmosphere extending much higher above the surface than previously thought.” Astronomers were expecting to find carbon monoxide in the atmosphere eventually. What they weren’t expecting was the amount. A researcher tells National Geographic the results were dramatic. “The new study... not only confirms the gas is there, it shows that the amount of carbon monoxide has doubled since 2000. ‘Think of [any gas doubling] on Earth over one decade,’ said study leader Jane Greaves...” Pluto’s atmosphere grows as it orbits closer to the sun. The extra heat evaporates gas from the surface. In the last 10 years, it’s grown so high, you could fit another Pluto in it. (Image source: Science Magazine) The problem, according to Science Magazine, is Pluto has been moving farther away from the sun for 20 years. “Pluto travels along a highly elliptical path and last passed closest to the sun in 1989. Many planetary scientists expected the atmosphere to shrink as the icy orb began receding from the sun’s warmth. The unanticipated expansion may be related to changes in the darkness of the orb’s surface a decade or so ago … Or ... long-term variations in the sun’s ultraviolet output...” The researchers say the dramatic change in Pluto’s atmosphere can help us understand the changes in Earth’s climate. And that’s not all: MIT Technology Review says the extra atmosphere gives Pluto the chance to wag its tail. “The thinking is that the expanding atmosphere is interacting with the solar wind and being shaped into a tail. That could throw the cat among the pigeons next time Pluto's status as a planet comes up for discussion. It gives ammunition to the naysayers who can now claim that far from being a planet or even a dwarf planet, Pluto is merely a giant comet.” The biggest news about Pluto is expected to come in 2015, when the spacecraft New Horizons is scheduled to give us the Planet’s first ever fly-by pictures.
