Antimatter Positrons Explain Gamma Ray Mystery In Milky Way Galaxy
2009-07-09 16:02:00 From ScienceDaily: Latest Science News: Astrophysicists have solved a mystery that led some scientists to speculate that the distribution of certain gamma rays in our Milky Way galaxy was evidence of a form of undetectable "dark matter" believed to make up much of the mass of the u
The Five Greatest Mysteries of Antimatter
2009-04-27 15:49:00 From New Scientist - Online News: It was not so long ago that we were hearing how CERN's Large Hadron Collider would produce planet-destroying black holes. Now a movie based on Dan Brown's blockbuster, due to hit the big screen next month, provides us with another supposed danger e

origin of antimatter surrounding the galactic center
2008-01-24 19:35:00 New research based on the four years of observations from the European Space Agency’s Integral (INTErnational Gamma-Ray Astrophysics Laboratory) satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center.Integral found that the cloud extends farther on the western side of the galactic center than it does on the eastern side. This imbalance matches the distribution of a population of binary star systems that contain black holes or neutron stars, strongly suggesting that these binaries are churning out at least half of the antimatter, and perhaps all of it.The cloud itself is roughly 10,000 light-years across, and generates the energy of about 10,000 Suns. The cloud shines brightly in gamma rays due to a reaction governed by Einstein’s famous equation E=mc^2. Negatively charged subatomic particles known as electrons collide with their antimatter counterparts, positively charged positron...

The mysterious source of this antimatter has now been discovered — sta
#28 Carnival of space & collecting antimatter
2007-11-10 17:35:00 The 28th carnival of space is now online at the Planetary Society's blog.An especially interesting entry is aboutcollecting natural antimatter.Antimatter readily annihilates when it contacts with normal matter, and releases the whole energy corresponding to its mass (E=mc2). This makes it especially useful for spacecraft propulsion.The recently finished report for the Nasa Institute for Advanced Concepts says:For example, 100 nanograms of antiprotons can be used to catalyze sub-critical nuclear reactions and drive a one metric ton of payload to 100 km/sec. ... In comparison, if traditional chemical propellants were used for the same task, nearly 109 metric tons of hydrogen and oxygen would have to be launched into space.And that would mean about 500,000 shuttle launches.Currently antimatter is generated at CERN and Fermilab, with capacities about 1 nanogram/year (10-9 grams). The production costs are estimated to be about $100 trillion per gram.The report investigates trapping an...

Researchers fire most powerful antimatter beam ever
2007-10-29 01:50:00 Now that the device is working, the team is looking for practical applications for the tech, including building an "antimatter telescope," which would allow even closer observations of atomic interactions. The antimatter device -- which apparently looks like a Star Trek warp reactor -- was developed as part of a two year project by NC State, the University of Michigan, and Oak Ridge National Labs. Scientists at North Carolina's PULSTAR nuclear reactor facility fired a positron bean five times stronger than any other ever created earlier this month, breaking a record previously held by a team in Germany. You know, whatever. Or they could use it to blow up the universe.
Most powerful antimatter beam ever, next stop Warp Drive?
2007-10-28 08:18:00 You know it's kind of odd how real life mimmicks science fiction over time. It's happened in all kinds of ways some are so similar its almost insane. From the current research into shields and lasers to aircraft designs and futuristic concept cars. Well it turns out that something else is on its way. Researchers from North Carolina's PULSTAR nuclear reactor facility have fired an antimatter beam that's five times stronger than any ever created in the past. What's interesting is the antimatter device at current is being researched for what it can be used for such as an antimatter telescope which would allow even closer observcations of atomic interactions. But what I find most interesting is that from the images this baby's looking a lot like the warp drive from star trek. This is probably even cooler than an life insurance no medical exam plan to a penny pincher. Those of you trekies that might recall, guess what powered the star trek warp engine, they kind of mention it in ...

Melyn Bragg - Antimatter
2007-10-06 08:18:00 reposted from: Melvyn Braggs Newsletter today Hello .... contradictions between matter and antimatter. One thing that fascinates me when I enter into the area of physics is the glossary that I usually get hold of. The glossary of physics terms. Antimatter itself, of course: “material made from antifermions”,fermions: “any particle that has odd-half-integer (1/2, 3/2 ...) intrinsic angular momentum (spin), measured in units of h-bar”, boson, hadron, kaon, photon, positron … I can understand why Christopher Marlowe was so entranced by the great names of cities and places which came out of the East and understand the allure of the shipping forecast to all of us – Seamus Heaney wrote a memorable poem about it which is a poetically-shaped listing of that reassuring, but somehow gallant, tour of these islands. And so to antimatter. Once again, you have to be impressed by the generosity of people who are at the coal-face of modern physics, taking the time and ...

Journalists and scientists - an antimatter explosion? [Evolving Thoughts]
2007-06-20 03:29:00 What happens when you put journalists in contact with scientists? To hear some people tell it, it results in an antimatter-matter explosion that destroys careers and causing black holes of ignorance in the general population, particularly when the density is already great, as in political circles. Tara, from the scientists’ perspective, gave a list of rules for science journalists. Her commentators broadly agreed, ranging from gentle to vociferous. Chris Mooney leapt to the defence of what is, after all, his profession (and one he’s damned good at if his book is anything to judge by), and Carl Zimmer came in with a balanced response and Kevin Padian’s rules. Now I, for my sins, have been a public relations guy for an academic institution, as well as for local government, a state government instrumentality, and for a largish university. My first job was in fact as the “copyboy” in the editorial room of a large metropolitan newspaper (*cough*), and t...
New form of matter-antimatter transformation observed for first time
2007-05-05 14:08:00 Whilst science fiction toys effortlessly with anti-matter, in reality it can be very hard to produce, so researchers around the world are celebrating a new break through in this area. For the first time, scientists using the BaBar experiment at the Stanford Linear Accelerator Center (SLAC) have observed the transition of one type of particle, the neutral D-meson, into its antimatter particle - a process known as 'mixing'. The new observation will be used as a test of the Standard Model, the current theory that best describes the entire universe's luminous matter and its associated forces.UK BaBar spokesman, Fergus Wilson of the Rutherford Appleton Lab said "D-meson mixing was first predicted over three decades ago but it is such an elusive phenomenon that it has taken until today to see it. The observation of D-meson mixing is yet another outstanding achievement for the BaBar experiment. The BaBar collaboration continues to make ground-breaking measurements that challenge our und...
