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…
The radiation could even provide physicists with clues to another outstanding problem about our universe: how the invisible “dark matter” and “dark energy,”…
A gas giant has been added to the short list of exoplanets discovered through direct imaging. It is located around GU Psc, a star three times less massive than…
Haze is usually composed of pollutants in the form of tiny suspended particles or fine mists/droplets emitted from vehicles, coal-burning power plants and…
Eight years ago Rudolf Grimm’s research group was the first to observe an Efimov state in an ultracold quantum gas. The Russian physicist Vitali Efimov…
Based on this census, an international team of scientists led by Timea Csengeri from the Max Planck Institute for Radio Astronomy in Bonn has estimated the…
On its first scientific mission the far-infrared spectrometer FIFI-LS (Field-Imaging Far-Infrared Line Spectrometer) developed by a team led by the University…
In order to make the plasma flow control technology more practical, the plasma authority must be improved at high wind speed. Dr. ZHANG Xin and his group from…
The nanostructures (particles of a microscopic size of between 1 and 100 nanometres) are coated in titanium oxide to which nitrogen has been added. This allows…
This time, Chang and his team have developed a new ultrafast light source for observing electron motion in molecules – made up of nuclei and electrons – at the…
People standing on a beach often feel the water tugging the sand away from under their feet. This is the undertow, the current that pulls water back into the…
Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position. This is the result of recent HADES…
Solar flares are powerful bursts of radiation.
This finding is very surprising, as the astronomers expected that any central rotation should have been erased by now due to the old age of these clusters.
Trapping light into a small volume is a useful way of amplifying optical effects. Optical cavities, for example, can enhance the interaction between light and…
“We live in a world in which the majority of work processes are aided by computers,” said Professor Dr André Hinkenjann, Director of the Institute of Visual…
Galaxies are typically comprised of several hundred billion stars and display a variety of shapes and sizes. The formation of galaxies is one of the most…
