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…
Astronomers found that active star formation upswells galaxies, like yeast helps bread rise. Using three powerful telescopes on the ground and in orbit, they…
For a number of years, scientists have been working on using electron spins to store and process information. A possible approach is to use a quantum system in…
“It's a bit like Legos,” said Ian Wong, an assistant professor in Brown's School of Engineering and co-author of the research. “We can attach polymers together…
Even today, fast data transfer in telecommunication networks employs short light pulses. Ultra broadband technology uses optical fiber links through which…
Conventional electron accelerators have become an indispensable tool in modern research. The extremely bright radiation generated by synchrotrons, or free…
In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin…
We generally imagine atomic nuclei to be more or less spherical, but always relatively chaotic, clusters of protons and neutrons. Experiments at the Argonne…
Although most of the more than 2,500 pulsars known are solitary objects, a few are found in tight binary systems. The discovery of the first of these, the…
NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.
Water has many ice phases that form under different pressure and temperature conditions. The effects of positive pressure have been explored extensively, with…
A pulsar is the core of a massive star that exploded as a supernova. In this stellar remnant, also called a neutron star, the equivalent mass of half a million…
Everyone will be familiar with playing a video on their computer that keeps pausing every few seconds and just won’t buffer properly. These stops and starts…
Reproducing experiments and results is a cornerstone of science, but researchers acknowledge that actually achieving this feat can be tricky. Specific…
Current smartwatches can recognise a limited number of particular activities, including yoga and running, but these are programmed in advance.
Most digital data is stored in the cloud as magnetic bits within massive numbers of magnetic disk drives. Over the past several decades these magnetic bits…
Venus rotates westward with a very low angular speed; it takes 243 Earth days to rotate once. The planet's atmosphere rotates in the same direction but at much…
