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…
The following expose presents a novel and patent-pending fluidic micro-pump. The pumping of the medium is performed without any mechanical moving parts and is…
The invention consists of an electrochemical measuring cell with redox mediators for measuring very low concentrations. Nevertheless, by means of designing…
Even some stars go ballistic, racing through interstellar space like bullets and tearing through clouds of gas.Images from NASA's Hubble Space Telescope reveal…
The new finding counters the previous explanation of the evenly spaced arrangement of small rocks on Mars. That explanation suggested the rocks were picked up…
Nanotechnology exploits the properties of materials on a nanometric scale, (a nanometer is one millionth of a millimeter). The ultimate limit for such…
The finding comes from a balloon-borne instrument named ARCADE, which stands for the Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission. In…
An image-recognition system developed by European researchers can hyperlink reality. It’s true. The MOBVIS system can recognise individual buildings in a photo…
Could a concept from information technology familiar to online file sharers be exploited to reduce road congestion and even traffic accidents? That is the…
A mysterious flash of light from somewhere near or far in the universe is still keeping astronomers in the dark long after it was first detected by NASA's…
In synch with the International Year of Astronomy (IYA), which marks the 400th anniversary of Galileo's discoveries, a group of astronomers and curators from…
“This observation required a rare and exceptionally bright event to allow us to probe the fragile environment where stars were forming just 3 billion years…
Nearly ten years ago, Chandra's “First Light” image of Cassiopeia A (Cas A) revealed previously unseen structures and detail. Now, after eight years of…

This sweeping panorama is the sharpest infrared picture ever made of the Galactic core. It offers a nearby laboratory for how massive stars form and influence…
That increase in speed, said Mark Reid, of the Harvard-Smithsonian Center for Astrophysics, increases the Milky Way's mass by 50 percent, bringing it even with…
The galactic center is wracked with powerful gravitational tides stirred by a 4 million solar-mass black hole. Those tides should rip apart molecular clouds…
