Most comprehensive map of the universe yet could pinpoint dark matter

By - April 30, 2015 1 Picture
Astrophysicists from the University of Waterloo have compiled the most comprehensive 3D map of our cosmic surroundings to date. The map describes how ordinary matter is distributed in space up to a distance of about a billion light-years away from us. This survey will help scientists better understand the distribution of dark matter and explain why, to some extent, galaxies are moving erratically with respect to us. Read More

LISA Pathfinder gravity probe moves to testing

A European Space Agency (ESA) mission aimed at testing new technologies for understanding the universe has left Britain for final testing before being launched into space. The LISA Pathfinder mission's propulsion and science modules left Airbus Defence and Space for Industrie Anlagen Betriebs Gesellschaft (IABG) in Germany for final tests before shipment to the ESA launch site in Kourou, French Guiana, where they will be shot into low-Earth orbit atop a Vega rocket.

Research suggests dark matter plays a significant role in our planet's mass extinction cycle

By - February 24, 2015 1 Picture
A new study carried out by Professor Michael Rampino of New York University suggests that dark matter may have had a part to play in the periodic mass extinction events that are known to have taken place throughout Earth's history. It takes our planet roughly 250 million years to circle the Milky Way, and around every 30 million years the Sun's orbit takes us through what is known as the galactic disk. The galactic disk is where the majority of the mass in our galaxy resides, and alongside it a thin disk of dark matter. Read More

New Planck map begins to unlock the secrets of the early universe

By - February 13, 2015 2 Pictures
ESA's Planck mission is yielding some surprising findings along with a beautiful new map of the Milky Way that breaks down some of the key elements of our galaxy. The telescope spent four years studying the cosmic microwave background radiation (CMB), a relic from the birth of the universe. The resulting data from this endeavor is now helping us refine how we measure matter, how we understand dark matter and generally just unraveling the secrets of the universe. Read More

The lighter side of dark matter

By - February 1, 2015 1 Picture
In spite of substantial scientific investigation and convincing indirect evidence, dark matter still eludes direct detection and its existence essentially remains a tantalizing, but unproven, hypothesis. Notwithstanding this, nearly 85 percent of the predicted mass of the universe remains unaccounted for, and dark matter theory is still the prime contender to explain where it may be. Researchers at the University of Southampton have theorized the existence of a new "lighter" dark matter particle in an effort to help unravel the mystery. Read More

GPS satellites to aid in hunt for elusive dark matter

By - November 18, 2014 1 Picture
Dark matter is hypothesized to account for the large amounts of "missing" invisible matter in the universe where visible objects such as stars, gas, and dust are insufficient to explain the total gravitational effects observed. Despite repeated and verifiable observational evidence supporting this hypothesis, the existence of dark matter remains unproven. However, recent research has suggested that the hunt for this elusive substance may be aided by detecting any changes in the synchronization between the individual atomic clocks on-board satellites in the orbiting GPS network and receivers on the ground as waves of dark matter pass between them and the surface of the Earth.
