On Monday, scientists in Europe said they have solved the case of the missing neutrinos, one of the enduring mysteries in the subatomic universe of particle physics. The researchers said the findings challenge core precepts of the so-called Standard Model of physics, and could have major implications for our understanding of matter in the universe. Neutrinos are electrically neutral particles that travel close to the speed of light. Physicists had observed for years that fewer neutrinos...

Astrophysicists at UC Santa Barbara are the first scientists to identify two white dwarf stars in an eclipsing binary system, allowing for the first direct radius measurement of a rare white dwarf composed of pure helium. The results will be published in the Astrophysical Journal Letters. These observations are the first to confirm a theory about a certain type of white dwarf star. The story began with observations by Justin Steinfadt, a UCSB physics graduate student who has been monitoring...

Observations of how the youngest-known neutron star has cooled over the past decade are giving astronomers new insights into the interior of these super-dense dead stars. Dr Wynn Ho will present the findings on Thursday April 15th at the RAS National Astronomy Meeting in Glasgow. Dr Ho, of the University of Southampton, and Dr Craig Heinke, of the University of Alberta in Canada, measured the temperature of the neutron star in the Cassiopeia A supernova remnant using data obtained by NASA's...

Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion -- dubbed the "dark flow" -- to twice the distance originally reported. "This is not something we set out to find, but we cannot make it go away," Kashlinsky said. "Now we see that it persists to much greater...

UCLA scientists to discuss XENON100, the newest dark matter detector Dark matter, for more than 70 years as mysterious and unknowable a subject to science as the legendary island of Atlantis has been to history, is bringing 140 scientists from the U.S., Europe and Asia to the Marriott Hotel in Marina del Rey for the ninth UCLA Symposium on Sources and Detection of Dark Matter and Dark Energy in the Universe. The three-day conference runs through Friday, Feb. 26. "Dark matter is one of the...

Even the biggest Star Trek fan would probably have trouble understanding the technical details of the research done by Particle Astrophysics Professor Wolfgang Rau. Professor Rau is the only Canadian researcher among the group of 60 scientists involved in the Cryogenic Dark Matter Search experiment (CDMS) whose latest findings are published in the latest edition of Science magazine. Professor Rau says the project is among the top two or three most important experiments on this subject in the...

Two University of Colorado at Boulder physicists are part of a collaborative team working with the U.S. Department of Energy's Brookhaven National Laboratory in New York that have created the hottest temperature matter ever measured in the universe -- 7.2 trillion degrees Fahrenheit. The team used Brookhaven's giant atom smasher, the Relativistic Heavy Ion Collider, or RHIC, to ram charged gold particles into each other billions of times, creating a "quark-gluon plasma" with a temperature...

New findings from NASA's Chandra X-ray Observatory have provided a major advance in understanding a type of supernova critical for studying the dark energy that astronomers think pervades the universe. The results show mergers of two dense stellar remnants are the likely cause of many of the supernovae that have been used to measure the accelerated expansion of the universe. These supernovae, called Type 1a, serve as cosmic mile markers to measure expansion of the universe because they can be...

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...
