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…
Stars are born when giant clouds of gas and dust collapse. Whenever one of the collapsing regions becomes hot and dense enough for nuclear fusion to set in, a…
Data recorded by NASA's Chandra X-ray Observatory of a neutron star as it passed through a dense patch of stellar wind emanating from its massive companion…
Flashback to the days when one tried learning a second language. Whether adult or child – a person’s ability to remember those nouns, verbs and adjectives…
Until a few decades ago it was unthinkable for physicists to carry out experiments with individual atomic particles. Erwin Schrödinger, one of the pioneers of…
Solitons are the most stable of all waves. Under conditions that result in the dispersion of all other waveforms, a soliton will continue undisturbed on its…
So far, a foggy cloud of hot gas has prevented astronomers from making sharp images of the supermassive black hole Sgr A* and causing doubt on its true nature….
We live in a polarized world. No, we aren't talking about politics — we're talking about light. Much of the light we see and use is partially polarized,…
Gamma-ray bursts are the most powerful explosions in the cosmos. These explosions last several seconds and emit the same amount of light as nearly all the…
It is one of the most vulnerable times for “secondary accidents,” which often can be worse than an original source of the slowdown, according to the U.S….
Their space radars TIRA and GESTRA present researchers with examples of their use at the ESA Neo and Debris Detection Conference from 22 to 24 January 2019, in…
The new sensor – capable of detecting vibrations of living cells – may revolutionise everything from medical devices to unmanned vehicles.
In 1915, Albert Einstein and Wander de Haas reported that changing the magnetization of a suspended iron rod by applying an external magnetic field leads to…
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken…
Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been…
Plasmas – hot gases consisting of chaotically-moving electrons, ions, atoms and molecules – can be found inside of stars, but they are also artificially…
Researchers of the Institute of Photonic Integration of the Eindhoven University of Technology (TU/e) have developed a 'hybrid technology' which shows the…
