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 properties of materials are determined by their atomic structure. If atoms and electrons change their positions, then the characteristics of a material…
On Dec. 7, 1995, NASA's historic Galileo probe plunged into Jupiter's atmosphere at 106,000 mph, relaying 58 minutes of data back to Earth before it was…
But one critical question has bedeviled astronomers for generations: Is there water deep in Jupiter's atmosphere, and if so, how much?
The Earth's magnetic field extends from pole to pole and is strongly affected by solar wind from the sun. This “wind” is a stream of charged particles…
In a finding that caps years of exploration into the tiny particle known as the Higgs boson, researchers have traced the fifth and most prominent way that the…
With an equator diameter of around 143,000 kilometers, Jupiter is the largest planet in the solar system and has 300 times the mass of the Earth. The formation…
But the wait was uniquely nerve-wracking for a group of scientists at Predictive Science Inc., a private research company in San Diego: They had just published…
They demonstrate, for the first time that, under the conditions used at the time of the experiment, an increased number of X-ray pulses per second as produced…
Over the past decades, nanoactuators for detection or probing of different biomolecules have attracted vast interest for example in the fields of biomedical,…
Animals in natural environments come into contact with many different surfaces, where the spectrum ranges from very smooth to very rough. Whereas humans wear…
A Vanderbilt team found the answer in a formula familiar to college physics students – a solution so simple and elegant, it was tough for reviewers to believe….
Especially the high costs of commercially available radio and position finding systems, amounting to more than 300 euros per person, have prevented these…
Polyisobutylene (PIB) is a workhorse polymer that is found in a multitude of products, ranging from chewing gum, to tires, to engine oil and gasoline…
This tiered “wedding cake,” which appears in images that show the energy level structure of the electrons, experimentally confirms how electrons interact in a…
Research on insulators with topologically protected surface conductivity – in short: topological insulators – is currently in vogue. Topological materials may…
Metals usually conduct heat extremely well. Local heating is distributed almost instantaneously through their free electrons. By contrast, insulating materials…
