At long last, a 3D picture of an interstellar cloud, a...

A duo of astronomers has accomplished a difficult feat: determining the 3-D structure of an interstellar cloud, the birth site of stars. The advance not only reveals the true structure of the molecular cloud Musca, which differs from previous assumptions in looking more like a pancake than a needle, but it could also lead to a better understanding of the evolution of interstellar clouds in…

Reconnection tames the turbulent magnetic fields around Earth

When the solar wind - which is really a driving rain of charged particles from the sun - strikes Earth's protective magnetic field, the shock generates roiling, turbulent magnetic fields that enshroud the planet and stretch for hundreds of thousands of miles. Where does all that turbulent energy go? One of NASA's space weather missions, called Magnetospheric Multiscale or MMS, has discovered one surprising way…

For how long will the USA remain the Nobel Prize leader?

Since first being awarded in 1901, most Nobel Prizes for science have gone to the USA, the United Kingdom, Germany and France. An empirical study by Professor Claudius Gros from the Institute for Theoretical Physics at the Goethe University in Frankfurt has now shown that the Nobel…

Because gravity determines so much of a live organism's behavior and growth, centrifuge-based experiments have long been a part…

Atmospheric seasons could signal alien life

RIVERSIDE, Calif. (http://www.ucr.edu) --Dozens of potentially habitable planets have been discovered outside our solar system, and many more are awaiting detection. Is anybody -- or anything -- there? The hunt for life in these places, which are impossible to visit in person, will begin with a search for biological products in their atmospheres. These atmospheric fingerprints of life, called biosignatures, will be detected using next-generation…

NASA spacecraft discovers new magnetic process in turbulent space

Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA's Magnetospheric Multiscale spacecraft -- MMS --have uncovered a new type of magnetic event in our near-Earth environment by using an innovative technique to squeeze extra information out of the data. Magnetic reconnection is one of…

New research reveals how energy dissipates outside Earth’s magnetic field

IMAGE: In this visualization, as the supersonic solar wind (yellow haze) flows around the Earth's magnetic field (blue wavy lines), it forms a highly turbulent boundary layer called the 'magnetosheath' (yellow... view more  Credit: NASA/GSFC Earth's magnetic field provides an invisible but crucial barrier that protects Earth from the solar wind--a stream of charged particles launched from the sun's outer layers. The protective properties of the…

NASA spacecraft finds new type of magnetic explosion

Four NASA spacecraft have observed magnetic reconnection in a turbulent region of the Earth's outer atmosphere known as the magnetosheath, the planet's first line of defense against the intensity of the solar wind. The new insights could help us understand how such phenomena affect Earth's atmosphere because of the potential impact on astronauts in space, satellites and electrical power industries. Frequent flyers know a thing…

Fleet of spacecraft spot long-sought-after process in the Earth’s magnetic field

A NASA mission has discovered an important process explaining the fate of energy contained in the turbulent magnetic fields surrounding the Earth. The phenomenon, discovered by NASA's four-spacecraft Magnetospheric Multiscale (MMS) mission, is small but provides crucial insight into turbulent plasmas. The Earth's magnetic field protects us from the solar wind, which is a stream of plasma coming from the Sun. Plasmas - streams of…
