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…
Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, scientists have demonstrated full quantum…
The new composite picture (viewable at http://www.spitzer.caltech.edu/glimpse360), using infrared images gathered over the last decade, was unveiled today…
University of Oregon physicists using a supercomputer and mathematically rich formulas have captured fundamental insights about what happens when objects…
The theory explains the transition phase to superconductivity, or “pseudogap” phase, which is one of the last obstacles to developing the next generation of…
Fusion is widely considered the ultimate goal of nuclear energy. While fission leaves behind radioactive waste that must be stored safely, fusion generates…
University of Utah electrical engineers fabricated the smallest plasma transistors that can withstand high temperatures and ionizing radiation found in a…
NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner radiation belt display a persistent pattern that resembles slanted…
Earth dodged a huge magnetic bullet from the sun on July 23, 2012.
Web viewers can zoom in and out, and pan around an area. Constructed from 10,581 pictures, the mosaic provides enough detail to see textures and subtle shading…
A team of U.S. cosmologists using the BICEP2 telescope at the South Pole announced this week that they have discovered the first direct evidence of the rapid…
The Canadian technology company of the same name is advertising the machine as a quantum computer. However, whether or not the machine does in fact use quantum…
Lithium-Ion-batteries often comprise collector foils made of chemically pre-treated aluminium. The chemical pre-treatment of such aluminium collector foils can be superseded by a plasma treatment of raw aluminium. More general, the patented method allows reduction of the contact resistance of different metal substrates.
Point defects, for example missing atoms (so called vacancies) significantly influence the performance and durability of modern materials. Even smallest defect…
NGC 2174 lies about 6400 light-years away in the constellation of Orion (The Hunter). Hubble previously viewed this part of the sky back in 2001, creating a…
Unlike comparable mid- and far-infrared detectors currently on the market, the detector developed by University of Michigan engineering researchers doesn't…
A new study led by the University of Colorado Boulder showed that as a group, volunteer counters who examined a particular patch of lunar real estate using…
