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…
“Bethe strings” are excitations of strongly bound electron spins in one-dimensional quantum spin systems. These quantum spin states are named after the…
Dark matter is increasingly puzzling. Around the world, physicists have been trying for decades to determine the nature of these matter particles, which do not…
The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields. Astrophysicists have long puzzled over…
Building a submarine gets tricky when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane.
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature…
How can an existing work unit be digitalized? Many manufacturing companies see this as a major issue for the vertical integration and retrofitting of their…
Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes….

Whenever Industrie 4.0 is mentioned, the general assumption is that processing and evaluating large volumes of data are part of the equation. Although modern…
A sunspot usually consists of a circular dark core (the umbra) with a vertical magnetic field and radially-elongated fine threads (the penumbra) with a…
Matt Reagor, lead author of the paper, says: “We've developed a technique that enables us to reduce interference between qubits as we add more and more qubits…
Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution: gravitational lensing, predicted by…
Like other large galaxies, our Milky Way is surrounded by smaller galaxies that orbit it as satellites. According to the standard model of cosmology that…
Now a team led by scientists from the Max Planck Institute for Structure and Dynamics (MPSD) has provided the first evidence of a hidden superconducting state…
Every galaxy harbours a supermassive black hole at its center. A new computer model now shows how these gravity monsters influence the large-scale structure of…
After an amateur astronomer recorded observations of a satellite in high Earth orbit on Jan. 20, 2018, his initial research suggested it was the Imager for…
