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…
Knowing the location of the centre of mass, determined using measurements from sites on Earth's surface, is important because it provides the reference frame…
Atoms on the surfaces and borderlines of matter behave differently to atoms inside its volume due to their position at the boundary. Significantly altering the…
The findings will be presented by lead researcher Ingrid Wilke, assistant professor of physics at Rensselaer, at the World of Photonics Congress in Munich,…
GRBs are the most powerful energy releases since the Big Bang and are so bright that they rival the whole Universe in luminosity. They last for a very short…

In 2004 Koichi Itagaki discovered an exploding star in the galaxy UGC4904 (78 million light years away in the Lynx constellation), which rapidly faded from…
Quantum computers have superior qualities in comparison to the type of computers currently in use. If they are realised, then quantum computers will be able to…
Stars in the early stages of life are surrounded by dust clouds that thin out and dissipate as the star reaches maturity, becoming rings in their final stages….
Physicists of the DZero experiment at the Department of Energy's Fermi National Accelerator Laboratory have discovered a new heavy particle, the Îb (pronounced…
The experiment allows ESA to take a step closer to exploiting entanglement as a way of communicating with satellites with total security. Quantum entanglement…
Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray…
