In their studies of a large, distant galaxy, a team of astronomers made a very interesting finding. They were able to pinpoint the location of a very small, dwarf galaxy – in orbit around its larger counterpart. Remarkably, the smaller galaxy appears to be made exclusively out of dark matter.
Even more intere... |

In a new study funded by the US National Science Foundation (NSF), experts were able to place very strong limits on the mass range in which dark matter can exist. Details of the research effort were published in the December 1 issue of the esteemed scientific journal Physical Review Letters.

When experts conduct studies of extrasolar planet, they tend to assess their potential for supporting life based on some of the traits they can distinguish. But there is often an overlooked factor, some experts say, and that is the influence of dark matter. In the image attached to this article, the distribution of d... |

Researchers working at the Coherent Germanium Neutrino Technology (CoGeNT) experiment – deep underground in a Minnesota mine – say that they may have found additional evidence on the existence of hypothesized, long-sought-for dark matter. A team in Italy has been reporting on seasonal variations in the pa... |

Scientists in the United States recently provided the first confirmation that an European collaboration of physicists actually saw particles thought to make up dark matter in a long-term experiment.
The American team, based in an abandoned iron mine in Minnesota, operates a germanium-based detector, which seeks to... |

A report detailing more than three months of scientific observations contains no clues that may indicate dark matter actually exists. The paper shows the conclusions of 100 days of surveys, conducted using the XENON100 experiment in Italy. The facility is operated by the Italian National Institute for Physics (INFN) ... |

Homestake Mine, the deepest such structure in the western hemisphere, was until 200 2 the home of a massive gold exploitation, that produced billions of dollars for North America. Now, it is being re-purposed as one of the most advanced dark matter detectors in the world. Locate in Black Hills, that large mine is now... |

Deep underground, inside a Canadian mine, researchers with the Sudbury Neutrino Observatory in Ontario are deploying a new detection chamber, aimed at identifying the elementary particles believed to make out dark matter. A large portion of the international scientific community believes that the elusive stuff makes ... |

For many years, physicists have been trying to determine what dark matter is, ever since it was proposed that its influence was the one holding galaxies together. Experts have attempted to find the particles that make up the elusive substance, thought to form much of the known Universe, though we can't seem to b... |

Experts have recently come to believe that some of the earliest stars in the Universe, which formed more than 13 billion years ago, may have been fueled by dark matter originally. This type of matter was hypothesized more than a decade ago, but thus far scientists have been unable to detect it directly. But some beli... |

For the last decade or so, astrophysicists have been trying to find signs of the elusive dark matter, the stuff believed to make up about 90 percent of the mass of the Universe. Its existence can only be inferred through the gravitational effects it has on galaxies and other celestial bodies around it, but physicists... |

Rumors around the Internet and the blogosphere have it that researchers working with the Cryogenic Dark Matter Search (CDMS) collaboration may have discovered certain signs of the elusive dark matter, the proposed force that acts like gravity, keeping galaxies together. The existence of this type of matter has been h... |

During 2008, a number of scientific observations conducted in the upper atmosphere and in deep space yielded very promising results for research teams looking for the elusive dark matter around our planet. Large amounts of high-energy electrons were discovered just outside the Earth, and astronomers hypothesized that... |

The current largely adopted view on dark matter implies that it's mostly made of Weakly Interacting Massive Particles (WIMPs). Although these are theoretical massive particles that scarcely interact with regular matter, making them very hard to detect, a huge effort has been made to discover them, on a global sc... |

A major step in the actual discovery of dark matter, or at least a honing of the discovery process, was performed by the PICASSO project taking place at SNOLAB, in Canada. Scientists came upon a method to refine the search by finding that, under certain conditions, dark matter's WIMPs yield different acoustic si... |

The construction of the 12 observation lines of the first underwater neutrino telescope, Antares, is now complete and for more than a month now, two of the observation lines have been operational, continuously looking for any sign of neutrino particles coming from out of space. Antares is part of the European Antares... |

The attention of the world has recently been focused on the startling assertion made by the DAMA experiment researchers claiming that they have found evidence of WIMP particles existence, possible constituents of dark matter, while the Large Hadron Collider was somehow forgotten for a brief period of time. The most p... |

Last week, physicists from the Dark Matter experiment running for the last five years under 1.4 kilometers of solid rock beneath the Gran Sasso mountain in Italy, presented their findings suggesting that dark matter particles had been discovered in the 250 kilograms sodium-iodide WIMP detector. Dark matter was first ... |
