Dark Matter Clues From The Center Of Our Galaxy
2014-04-03 13:57:46

[ Watch the Video: Fermi Data Hints At New Dark Matter Clues ] Francis Reddym, NASA Goddard Space Flight Center A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe. Using publicly available data from NASA's Fermi Gamma-ray Space Telescope, independent scientists at the Fermi National Accelerator Laboratory (Fermilab), the...

A University of Maryland research team provides visual evidence confirming computer simulations of a special type of ripple that dissipates energy in extremely cold liquid helium. The research could lead to advances in superconductors. College Park, MD (PRWEB) March 24, 2014 Draining the water from a bathtub causes a spinning tornado to appear. The downward flow of water into the drain causes the water to rotate, and as the rotation speeds up, a vortex forms that obeys the laws of...

Dark Matter Results From LUX Confirmed After Recalibration - WIMPs Still Not Detected
2014-02-21 08:47:17

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dark matter research, like all experiments involving particle and astrophysical detections, relies on sorting out the desired events (the source events) from the noise (the background events). Since the interactions occur at a quantum level, the statistical process of sorting through the data is laborious, but also, more importantly, relies on your ability to calibrate and understand the instrument. Back in October the Large...

What's so 'super' about this superfluid Atomtronics is an emerging technology whereby physicists use ensembles of atoms to build analogs to electronic circuit elements. Modern electronics relies on utilizing the charge properties of the electron. Using lasers and magnetic fields, atomic systems can be engineered to have behavior analogous to that of electrons, making them an exciting platform for studying and generating alternatives to charge-based electronics. Using a superfluid...

New Look At Old Galactic Friend
2014-02-07 09:05:06

NASA Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short). This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central supermassive black hole. Since then, Chandra has returned its attention to this galaxy, each time gathering more data. And, like an old family photo that has been digitally restored, new processing techniques are providing...

Black Holes Unlikely To Help Explain Dark Matter

[ Watch the Video: Dark Matter Not Linked To Primordial Black Holes ] redOrbit Staff & Wire Reports - Your Universe Online Dark matter, the mysterious substance that comprises more than 85 percent of the universe, is unlikely to be made of primordial black holes due to the existence of neutron stars, astrophysicists from the University of Lisbon in Portugal and the Harvard-Smithsonian Center for Astrophysics (CfA) claim in a new study. The theory, originally proposed by Stephen...

[ Watch the Video: Turn About Is Fair Play - Black Hole Caught Orbiting A Star ] John P. Millis, PhD for redOrbit.com - Your Universe Online Black holes, by their very definition, are difficult to find. Their density is so great, that light cannot be given off directly, and photons that stray too close are absorbed into the gravitational well. So researchers have to rely on indirect evidence that a black hole is present by searching for their effects on other nearby objects....

Gravity Clues From Stellar Triple System
2014-01-06 03:39:45

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new study in Nature. Using the National Science Foundation's Green Bank Telescope (GBT), the study authors were able to locate the pulsar along with two white dwarf stars in a compact area...

Rare Binary White Dwarf Systems
2013-12-20 08:30:50

John P. Millis, PhD for redOrbit.com - Your Universe Online Nearly a half-century ago, astronomers discovered a strange star in the Canes Venatici constellation. It was later determined that the unusual properties of the object arose because it was not an isolated star at all, but rather a very tight binary system. With an orbital period of 18 minutes – for comparison the orbit of Mercury around the Sun takes about 88 Earth days – the individual members of the system are incredibly...

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....

White Dwarf -- A white dwarf is a a star supported by electron degeneracy. A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf. A typical white dwarf is half as massive as the Sun, yet only...

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first...

Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
