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…
Physicists from the University of Stuttgart show the first experimental proof of a molecule consisting of two identical atoms that exhibits a permanent…
For over a decade, Intel’s widely used copy protection HDCP has been trusted by the media industry, which carries out business in high-resolution digital video…
If dark matter exists in the universe, scientists now have set the strongest limit to date on its mass.In a paper to be published on Dec. 1 in Physical Review…
The most common causes of security issues in today’s software are not inadequate network security, poor security protocols or weak encryption mechanisms. In…

Aging bright stars in the cluster glow in intense shades of red and blue. The majority of middle-aged stars, several billions of years old, are whitish in…
By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the…
Lasers as sources for coherent and intense light are used in many high-tech applications and medical devices. Generally, the generation of Laser-light is…
Approval to move forward came during a recent Agency Project Management Council (APMC) meeting at NASA Headquarters. “I am very proud of the entire TDRS civil…
“Mars either has more gusts of wind than we knew about before, or the winds are capable of transporting more sand,” said Nathan Bridges, planetary scientist at…
Type Ia supernovae form when a white dwarf star – the left-over cinder of a star like our Sun – accumulates so much mass from a companion star that it…
The researchers also identified large masses of previously undetected material surrounding galaxies, and described the large-scale flows of this gas. The…
Researchers at the University of Pittsburgh have made advances in better understanding correlated quantum matter that could change technology as we know it,…
Led by Chang-Beom Eom, a UW-Madison professor of materials science and engineering and physics, the multi-institutional team published its results in the Nov….
An electrical spark in a drop of water creates a bubble of hot vapor. As the bubble rapidly expands and cools, pressure from the surrounding liquid pushes…
This ongoing recycling keeps galaxies from emptying their “fuel tanks” and therefore stretches out their star-forming epoch to over 10 billion years. However,…
