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…
When two uncharged objects are placed in a vacuum with no external fields, we wouldn’t expect them to have any force between them other than gravity. Quantum…
An international team of researchers has developed a numerical modeling technique to study specific types of particles called excitons, which consist of a…
Adaptive Optics (AO) corrects for the blurring effect introduced by the Earth's atmosphere. This turbulence causes the stars to twinkle in a way that delights…
The worldwide attempt to increase the speed of supercomputers merely by increasing the number of processor cores on individual chips unexpectedly worsens…
For over a year, the SIGAP system has been managing around 100 procedures, some of which use more than 100 screens. The results are well above expectations,…
The Meta-Mole, created by the Centre for Design in the Digital Economy (D-LAB) based within the University’s Institute of Digital Innovation, will ultimately…
NGC 2818 is one of very few planetary nebulae in our galaxy located within an open cluster. Open clusters, in general, are loosely bound and they disperse over…
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at…
They observed dust forming around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, giving them a…
The new polarization-matched LED, developed in collaboration with Samsung Electro-Mechanics, exhibits an 18 percent increase in light output and a 22 percent…
Nanotubes, the tiny honeycomb cylinders of carbon atoms only a few nanometers wide, are perhaps the signature material of modern engineering research, but…
The transit event causes a small drop in the observed starlight, which can then be detected. Fifty-five exoplanets have been detected this way since the…
The process takes place in binary stars – star systems consisting of two stars orbiting around their common centre of mass. This helps to resolve a long…
The official Opening Ceremony for the International Year of Astronomy 2009 (IYA2009) began today. It is taking place at the United Nations Educational,…
This invention is developed for non contact treatment of surfaces of different materials to get more adhesive power between a material and a coating.Further…
There are just five so-called Soft Gamma-ray Repeaters (SGRs) known, four in the Milky Way and one in our satellite galaxy, the Large Magellanic Cloud. Each is…
