Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
Astronomers have, for the first time, directly imaged a snow line at another star. Using the new Atacama Larger Millimeter/submillimeter Array (ALMA) telescope…
“The beauty of these measurements lies in the fact that these are the first really high-precision measurements of the composition of Mars' atmosphere,” said…
The picture of the world of the inscrutable neutrinos is getting clearer: today at the European Physical Society meeting in Stockholm, the international T2K…
“We are conducting this line of research because it opens up a way to create new responsive and intelligent systems and materials,” said Dr. Robin Ras of Aalto…
Vinh-Tan Nguyen and co-workers at the A*STAR Institute of High Performance Computing in Singapore have developed a more robust and efficient way to simulate…
Tiny optical components – the heart of modern communications systems – might one day increase the operational speed of computers. When designing these…
A team led by John Hagopian, an optics engineer at NASA’s Goddard Space Flight Center in Greenbelt, Md., has demonstrated that it can grow a uniform layer of…
Kinect technology recognizes a person's movements and posture and transfers them to an avatar in a virtual environment. In the same way that a player moves…
Safety is a key priority when designing and building a tunnel. All information relating to the equipment used in the tunnel and traffic conditions converges at…
Every tunnel has its own, unique safety requirements depending on the location, design, height and level of traffic. Even seemingly insignificant events can…
In 2011 ESO's Very Large Telescope (VLT) discovered a gas cloud with several times the mass of the Earth accelerating towards the black hole at the centre of…
These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 560 miles per second, which is a fairly typical speed for CMEs….
Magnetic reconnection happens when magnetic field lines come together, break apart and then exchange partners, snapping into new positions and releasing a jolt…
The moon, designated S/2004 N 1, is estimated to be no more than 12 miles across, making it the smallest known moon in the Neptunian system. It is so small and…
This invention enables for the first time the production of complex, non-developable surfaces with thermoplastic in-situ tape placement. In doing so, staple…
