Fermi Telescope Turns to Dark Matter Search
2013-01-21 10:58:25

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online For much of the last century, scientists have been searching for a mysterious substance thought to make up about 85 percent of the total mass of the Universe. Without it, galactic rotation curves, galaxy interactions and the very structure of the Universe are inconsistent with our knowledge of physics. Yet, this so-called dark matter remains elusive. One reason researchers have had such a difficult time finding and...

Researchers Disprove Pulsar Glitch Theory
2012-12-18 16:21:44

Lee Rannals for redOrbit.com — Your Universe Online Researchers reported in the journal Physical Review Letters that they have found a "glitch" in a 40-year-old theory explaining the periodic speeding up or "glitching" of pulsars. Pulsars emit a rotating beam of electromagnetic radiation, which can be detected by powerful telescopes once it sweeps past the Earth. The cosmic objects, which are highly magnetized rotating neutron stars formed from the remains of supernovae, rotate...

Renaissance Artwork Shows History Of Wormholes
2012-11-21 10:36:50

Brett Smith for redOrbit.com - Your Universe Online European Renaissance printers probably knew they were recording history for future generations, but what they didn´t realize is that they were also recording events related to biological history. Blair Hedges, a professor of biology at Penn State University, has discovered ℠wormholes´ that pock-marked European printed art from that time period were formed by two different types of beetles, which had separate, clearly...

Dark Matter Detector Gets Helping Hand From Livermore Team
2012-11-16 05:58:38

April Flowers for redOrbit.com - Your Universe Online Nearly a mile underground beneath the Black Hills of South Dakota, scientists from Lawrence Livermore National Laboratory (LLNL) are using a tank to make key contributions to a physics experiment that will look for one of nature's most elusive particles, "dark matter." The Large Underground Xenon (LUX) experiment located at the Sanford Underground Research Facility in Lead, SD is the most sensitive detector of its kind to look for...

The Local Universe Offered Up In Unprecedented Detail
2012-10-31 13:21:28

Lee Rannals for redOrbit.com - Your Universe Online The intimate details of 100 galaxies in the local universe have been published by the Calar Alto Legacy Integral Field Area survey (CALIFA). The survey offers up new data, representing the first large-scale effort at "two plus one" mapping of galaxies. For every pixel within each two-dimensional image, scientists could perform a detailed analysis and provide information about dynamics and chemical composition. This information could...

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using simulations were able to catch the Large Magellanic Cloud (LMC) in the act of stealing stars away from its neighbor, the Small Magellanic Cloud (SMC). The team was trying to look for massive compact halo objects (MACHOs) in order to find out if they could be a major component of dark matter. In order for MACHOs to make up dark matter, they must be so faint that they can't be directly detected. When studying the...

New Scenario for the Birth of Type Ia Supernovae
2012-10-26 05:49:37

Lee Rannals for redOrbit.com - Your Universe Online Astronomer J. Craig Wheeler reports in The Astrophysical Journal that he has a new theory on the identity of the "parents" of Type Ia supernovae. Wheeler said that current theories of Type Ia parents do not correctly match up with telescope data on actual supernovae. There are two models today that attempt to explain how Type Ia supernovae are born, the first being "single-degenerate model." In this model, a binary star is made...

Superconductors: Technologies and Global Markets -BCC Research Wellesley, MA (PRWEB) October 25, 2012 According to a new technical market research report, SUPERCONDUCTORS: TECHNOLOGIES AND GLOBAL MARKETS (AVM066C) from BCC Research (http://www.bccresearch.com), the global market for superconductor technologies was valued at nearly $1.7 billion in 2011 and should reach $1.8 billion in 2012. Total market value is expected to reach $3.3 billion in 2017 after increasing at a five-year compound...

Prestigious Panofsky Prize Won By Stanford's Blas Cabrera For Dark Matter Work

The search for dark matter runs deep with physicists Blas Cabrera and Bernard Sadoulet, who have chased this mystery far underground and will be recognized for their work as joint recipients of the 2013 W.K.H. Panofsky Prize in Experimental Particle Physics.

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...
