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…
NASA's Hubble Space Telescope has identified a star that was one million times brighter than the sun before it exploded as a supernova in 2005. According to…
Along with scientists at the University of Sheffield and California State University, the researchers have detected giant twisting waves in the lower…
The end of the Launch and Early Orbit Phase (LEOP) came overnight after GOCE was switched to Fine Pointing Mode. This means that all of its systems are working…
NASA's Kepler spacecraft just launched to find such worlds. Once the search succeeds, the next questions driving research will be: Is that planet habitable?…
A star is a large ball of hot gas and in its incredibly hot interior hydrogen atoms combine to form helium, which subsequently forms carbon, other heavier…
In the first observation if its kind, scientists at the Weizmann Institute of Science and San Diego State University were able to watch what happens when a…
Researchers at Rensselaer Polytechnic Institute have discovered the origins of nanorod diameter, demonstrating that the competition and collaboration among…
Development of the device brings researchers a big step closer to higher speed electronics and higher performance electrical and optical integrated circuits.The mixing device accepts two electrical inputs and produces an optical signal that was measured at frequencies of up to 22.7 gigahertz. The frequency range was limited by the bandwidth of the detector employed in the measurements, not by the transistor device.“…
The picture that emerges from these first-ever simultaneous observations with optical, X-ray and new-generation gamma-ray telescopes is much more complex than…
Lawrence Livermore National Laboratory scientists have for the first time converted the highest frequency sounds into light by reversing a process that…
The Gregor Solar Telescope saw sunlight for the first time at 14:55 UT on Thursday, March 12, 2009. This picture shows the image of the Sun on the field stop…
Three members of the faculty at Stevens Institute of Technology recently collaborated on a paper focusing on free-space optical communication, which appears in…
“We found more support for the idea that biological molecules, like amino acids, created in space and brought to Earth by meteorite impacts help explain why…
The invention comprises designed novel biologically highly potent ansamitocin analogues for tumor therapy, inlcuding among other new 19-deschloro and demethoxy…
The world market for cancer diagnosis is estimated to be 3.5 billion dollars for 2010. Scientists at the University of Goettingen identified a new diagnostic…
