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…
School physics teaches that the basis of an ordinary mirror is a thin aluminum or silver foil. Glass, which is in fact a large transparent piece of ordinary…
All today’s commercial drones use GPS, which works fine above building roofs and in high altitudes. But what, when the drones have to navigate autonomously at…
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image…
New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their…
The Physikalisch-Technische Bundesanstalt (PTB) is known for providing time e.g. for radio-controlled clocks. For this purpose, it operates some of the best…
A technical revolution came when the US engineer Jack Kilby developed the integrated circuit in the 1960s. Initially assembled in a pocket calculator, this…
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by…
Dust is everywhere–not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a nuisance by blocking the light of distant…
The measurements were performed using scanning tunnelling microscopy (STM). The researchers have published their results in the specialist journal Nanoscale.
Particularly for SMEs, it is often difficult to find a secure and reliable option among the many smaller cloud service providers on the market. On the back of…
Some ten years ago, Johannes Gutenberg University Mainz (JGU) entered a new field of research by starting to generate ultracold neutrons (UCN) for use in…
An international team of astronomers with the involvement of the University of Göttingen has conducted the deepest spectroscopic survey ever. Using the MUSE…
Black holes absorb light and all other forms of radiation, making them impossible to detect directly. But the effects of black holes, in particular accretion…
Exoplanet hunters watch stars for a few telltale signs that there might be planets in orbit, like changes in the color and brightness of the starlight. For…
Data travels through thousands of miles of fiber optic cables underneath the world's oceans–via pulses of light. And according to experts, the data in these…
Using data from the Arecibo Observatory, Puerto Rico, and the Green Bank Telescope, West Virginia, astronomers have shown that the radio bursts from the…
