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…

Alignment of the optical components with micrometer accuracy
The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the…
If you want to build the most accurate clock in the world, you need something that “ticks” very fast and extremely precise. In an atomic clock, electrons are…
The enormous black hole at the center of our galaxy is having an unusually large meal of interstellar gas and dust, and researchers don't yet understand why.
Astronomers at the Center for Space Exochemistry Data at the University College London in the United Kingdom used data from NASA's Hubble Space Telescope to…
While billed as a “challenge,” the organizers had no intention of declaring a winner, as the technologies focused on different aspects of leak detection, such…
Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for…
