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…
Using the STEREO data, scientists at NASA's Goddard Space Flight Center in Greenbelt, Md. clocked this giant cloud, known as a coronal mass ejection, or CME,…
The ions (electrically charged atoms) travel 100 times faster than was possible before across a few hundred micrometers in an ion trap—a single ion can go 370…
The system works by measuring differences in gamma radiation emitted when atoms in radioactive elements “decay,” or lose energy. This rate of decay is widely…
This new technique expands the range of X-ray research possible for biology and many aspects of nanotechnology, particularly nanofilms, photonics, and micro-…
Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are…
His paper focused on bacteria that live in environments that are salty, but not with sodium chloride – the kind of salt we're used to. It has to do with…
