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…
Looking at a bright, nearby baby star and the dust swirling in its cradle, astronomers from the University of Illinois and six collaborating institutions were…
This happened on April 21, 2014, when Hubble was being used to monitor changes in Jupiter's immense Great Red Spot (GRS) storm. During the exposures, the…
This novel software technique automates the comparison of HTML pages across many browsers and a diverse range of formats. In a first step, screen shots from different browser and format combinations are automatically superimposed and compared. Relevant differences are highlighted in color to alert the web designer where additional work is required. To scale up for a large number of pages, the process can generate key numerical metrics that characterize the visual match.
Cars take on continuously more tasks: They communicate with each other, defuse critical traffic situations and will steer automatically in the future. All of…
In a paper published in the prestigious journal Physical Review X, Professor Howard Wiseman and Dr Michael Hall from Griffith's Centre for Quantum Dynamics,…
Novel electro-spun fibers with integrated molecular switches (e.g. spin-crossover compounds) offer a multitude of interesting applications in the field of bio-medical research and microsensor technology. Future applications can be the new implants like e.g. cochlea implants.
With their new software the SnT researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining….
“The Lunar Reconnaissance Orbiter Camera (LROC) team recently developed a new computer tool to search Narrow Angle Camera (NAC) before and after image pairs…
New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, in a helium bubble.
Each second, the sun hurls millions of tons of hot, charged plasma gas into space. This volatile “solar wind” buffets the magnetosphere, the magnetic field…
Researchers have improved plasma performance by applying lithium coatings to the walls of fusion facilities. But a complete understanding of the mechanism…
Comet Siding Spring – an Oort Cloud comet that may contain material from the formation of the solar system some 4.6 billion years ago – was making its first…
X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three…
Astronomers with the National Science Foundation (NSF)-funded National Optical Astronomy Observatory (NOAO) captured pictures not only of Thursday's partial…
The first images of a nova during its early fireball stage–when it ejects material, and gases expand and cool–show that this activity is more complicated…
Distinguished Professor Sheldon Stone and his colleagues recently announced their findings at a workshop at CERN in Geneva, Switzerland. Titled “Implications…
