Stars that Eat Dark Matter Live Longer

A recent study indicates that there are stars in the proximity of the Milky Way's core that feed on dark matter, thus prolonging their lifespan with more than a billion years. Finding them would possibly help understanding what dark matter really is and how exactly it functions.

A Chance to See Dark Matter

Most of the matter in the universe is the mysterious dark matter, which astronomers can detect through gravitational effects but cannot actually see. The visible matter, or baryonic matter, that we're familiar with seems to make up only about 5% of the known universe compared to the 25% of dark matter!

Dark Matter Discovered Near Solar System?

gpronger writes "The ATIC (Advanced Thin Ionization Calorimeter) has potentially discovered the presence of dark matter close (only 3000 light-years) to our solar system. The system detected a large amount of high energy cosmic rays which match the theoretical signature of dark matter annihilating itself. The universe is believed to be composed of about 25% dark matter, but there has been little evidence of it. This discovery, if correct, would be the first." The paper was published in Nature, but it requires a subscription to see beyond the abstract.

Are We Close to Finding Dark Matter?

Scientists say he search for the mysterious substance which makes up most of the Universe could soon be at an end. A massive computer simulation was used to show the evolution of a galaxy like the Milky Way, and analysts were able to "see" gamma-rays given off by dark matter. Dark matter is believed to account for 85 per cent of the Universe's mass but has remained invisible to telescopes since scientists inferred its existence from its gravitational effects more than 75 years ago. If the computations are correct, the findings could help NASA's Fermi Telescope to search for the dark matter and open a new chapter in our understanding of the Universe.

Dark matter may shine with invisible 'dark light'

Mysterious dark matter could be shining with its own private kind of light. This "dark radiation" would be invisible to us, but could still have visible effects.

Mysterious Dark Matter Might Actually Glow

The strange stuff makes up about 85 percent of the heft of the universe. It's invisible, but researchers know it's there because there is not enough regular matter -- stars and planets and gas and dust -- to hold galaxies and galaxy clusters together. Some other unseen material, dubbed dark matter, must be gluing things together.

Simulation points scientists to dark matter

This simulation shows the projected distribution of dark matter in the Milky Way. Myriad concentrations of dark matter are embedded within the galaxy's halo, and their dense centers emit energetic gamma rays from the annihilation of particles.

Space Dust Is Dark Matter

A small number of scientists defines space dust as the observable portion of dark matter. Space dust is comprised of small particles (about 0.1 mm) which reflect light on a very large scale. This is what can be seen of dark matter, not observable directly, but its hypothetical effects have been noticed.

Where will new Fermi telescope find dark matter?

More than a billion particles were included in a simulation of dark matter in a Milky Way-like galaxy. The annihilation of dark matter in a cloud-like halo around the galaxy should produce a diffuse glow of gamma rays that could be detected by NASA's new Fermi telescope (Simulation: Virgo Consortium)

Simulations Predict Where We Can Find Dark Matter

p1234 writes with this excerpt from the Max Planck Institute for Astrophysics: "Simulations by the Virgo team show how the Milky Way's halo grew through a series of violent collisions and mergers from millions of much smaller clumps that emerged from the Big Bang. ... If Fermi does detect the predicted emission from the Milky Way's smooth inner halo, then it may, if we are lucky, also see gamma-rays from small (and otherwise invisible) clumps of dark matter which happen to lie particularly close to the Sun. ... The largest simulation took 3.5 million processor hours to complete. Volker Springel was responsible for shepherding the calculation through the machine and said: 'At times I thought it would never finish.' Max Planck Director, Professor Simon White, remarked that 'These calculations finally allow us to see what the dark matter dis

Scientists closer to finding dark matter

Researchers may be closer to detecting dark matter, the mysterious matter that scientists believe makes up the majority of the observable universe.

The Whereabouts of Dark Matter Revealed

According to a Reuters article, a recent vast-scale simulation of the creation and evolution of a Milky Way-type of galaxy has indicated some potential places in space where scientists should search for dark matter. Although the existence of the matter that forms a huge part of the universe has been known for a long time, and theoretically proved, all efforts to actually discover it turned out to be useless. However, in light of their research, experts may yet stand a chance.

Anti-Matter Created By Laser At Livermore

zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.

Do We Live In a Giant Cosmic Bubble?

Khemisty writes "Earth may be trapped in an abnormal bubble of space-time that is particularly void of matter. Scientists say this condition could account for the apparent acceleration of the universe's expansion, for which dark energy currently is the leading explanation. Until now, there has been no good way to choose between dark energy or the void explanation, but a new study outlines a potential test of the bubble scenario. If we were in an unusually sparse area of the universe, then things could look farther away than they really are and there would be no need to rely on dark energy as an explanation for certain astronomical observations. 'If we lived in a very large under-density, then the space-time itself wouldn't be accelerating,' said researcher Timothy Clifton of Oxford University in England.

AMD and Red Hat Demonstrate Live Migration of Virtual Machines

AMD, in collaboration with Red Hat, have demonstrated the "live migration" of a virtual machine across vendor platforms. Live migration enables the movement of running virtual machines from one physical server to another without disrupting service to the end user, something that, till now, has only been demonstrated across systems based on one vendor's platforms. The live migration demonstration moves a live VM from an dual socket Intel Xeon DP Quad Core E5420-based system to a system based on the forthcoming 45nm Quad-Core AMD Opteron processor, utilizing Red Hat's high-performance open source virtualization software.
