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…
On the quest for novel solutions for future information technology, scientists from the University of Hamburg and the Forschungszentrum Jülich managed to…
An international group of astronomers including a scientist from the University of Göttingen has found an explanation of the long-standing mystery of why…
This new detection is considered one of the most reliable distance measurements of a galaxy that existed in the early universe, said the Hubble researchers….
Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today's chips, an…
Diamondoids are molecules whose framework structure represents a section of the diamond lattice. Due to their size in the range of 0.5 ? 2 nm, they can be considered as ?nano diamonds? with a hydrogen-terminated surface. Despite their small size, they comprise several properties which are characteristic for diamonds, such as a negative electron affinity and, in particular, chemical inertness.
The test procedure demonstrates the efficacy of substances and/or methods which eliminate infectivity using several quantitative measurement parameters (HBsAg, HBeAg, mRNA, cccDNA) for the detection of HBV infection after a titer reduction by more than 4 log 10 steps and is, thus, the first HBV infectivity test to meet the new guidelines of the Robert Koch Institute (RKI) and the German Association for the Control of Virus Diseases (DVV) for the efficacy of disinfectants and virus-inactivating procedures.
Now, for the first time ever, an international team of researchers has successfully tested a new model that explains how magnetic fields form these emissions…
Their model predicts that a bright hot star, which is the binary companion to an exploding object, remains after the explosion. To verify their theory, the…
The new information will help researchers better understand how our nearest star transfers energy through its atmosphere and track the dynamic solar activity…
This galaxy offers a peek back to the very early formative years of the universe and may just be the tip of the iceberg.
To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now…
The KBOs were detected through a dedicated Hubble observing program by a New Horizons search team that was awarded telescope time for this purpose.
This question has baffled astronomers for decades. Today, a team led by Paola Testa of the Harvard-Smithsonian Center for Astrophysics (CfA) is…
Using a patented experimental device and large-scale numerical simulations, the team obtained data consistent with astrophysical observations.
For as long as astronomers have been looking to the skies, we have had just one planetary system—our own—to study in depth. That means we have only…
These new radio observations, which are the highest sensitivity of their kind ever undertaken, reveal that within a well-defined boundary around our Galaxy,…
