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…
This finding was announced today by theorists from the Stanford Institute for Materials and Energy Science (SIMES), a joint institute of the Department of…
ESA's Mars Express spacecraft orbits the Red Planet in a highly elliptical, polar orbit that brings it close to Phobos every five months. It is the only…
These include geomagnetic storm, hazardous cosmic particles, space weather etc. Understanding the behavior of solar wind is therefore very critical. In situ…
But direct observation by the Chandra orbiting telescope have changed all that and led to “the first characterization of the spatial, thermal, chemical and…
Visible light and X-rays are different types of radiation. Visible light, for example, doesn’t penetrate the human body, whereas X-rays are absorbed weakly and…

Unfortunately, that is far from the case with many of today's machines. Beneath their smooth exteriors, modern computers behave in wildly unpredictable ways,…
“This is not something we set out to find, but we cannot make it go away,” Kashlinsky said. “Now we see that it persists to much greater distances — as far as…
The energy of ions impacting surfaces during plasma processing is crucial in determining both
