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…
These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.Experimental NASA research models, based on observations from NASA's Solar Terrestrial Relations Observatory and ESA/NASA's Solar and Heliospheric Observatory show that the CME left the sun at speeds of around 1350 miles per second, which is a fast speed for CMEs….
Nestled inside this constantly changing magnetic bubble lies a donut of charged particles generally aligned with Earth’s equator. Known as the ring current,…
But transistors based on semiconductors can only get so small. “At the rate the current technology is progressing, in 10 or 20 years, they won’t be able to get…

The resulting hybrid technology could eventually lead to computer and data-storage chips that pack more components in a given area and are faster and less…
When two galaxies stray too close to each other they begin to interact, causing spectacular changes in both objects. In some cases the two can merge — but in…
The eruption and subsequent splashdown were observed in spectacular detail by NASA's Solar Dynamics Observatory. This spacecraft watches the Sun 24 hours a…
Picture two light beams intersecting one another in space. When the beams touch one another, does the light bend? Reflect? Combine into a single beam? The…
The projects with a total value of 31 million euro and a consortium of 29 partners from industry and research are the first two projects that have been…
As reported in the journal Nature, important conclusions about the nature of the forces between the protons and neutrons in nuclei can be drawn by comparing…
The research, done at the Georgia Institute of Technology, used a new type of optical trap that simultaneously confined both ground-state and highly-excited…
