GPS satellites to aid in hunt for elusive dark matter

By - November 18, 2014
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.

Reaching space in a balloon may sound like something out of a children’s book, but Spain’s zero2infinity company doesn't think so. The Barcelona-based company specializes in near-space balloon flights for scientific and engineering clients, and is working on a nanosatellite launch vehicle called bloostar, which uses a high-altitude balloon as a first stage and rockets for reaching orbit.

New map shows world's seafloor in unprecedented detail

By - October 3, 2014 8 Pictures
Given they aren't covered by oceans, it's maybe not so surprising that we know more about the topography of the Moon and Mars than we do about Earth's ocean depths. But researchers have evened the score at least a little with the creation of a new map of the world's seafloor. Twice as accurate as the previous version produced almost 20 years ago, the new map details thousands of previously uncharted mountains and provides new clues on the formation of the continents.
