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…
But that doesn’t work for knit sweaters. To make the image realistic, the computer has to simulate the surface right down to the intricate intertwining of yarn.
The evidence indicates that the missing planet was devoured as the star began expanding into a “red giant” — the stellar equivalent of advanced age. “A similar…
Now, a group of researchers at UC Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number — in this case the…
A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission….
Graphene — a single layer of carbon atoms packed in a hexagonal lattice — has a number of appealing properties owing to its two-dimensional geometry.It has,…
Much the same must currently be done to understand the various motions at work in the great space weather system that links the sun and Earth as the sun shoots…
What at first was thought to be only one cluster in the core of the massive star-forming region 30 Doradus (also known as the Tarantula Nebula) has been found…
For data transmission over the Internet, electrical computer signals are converted into light signals and conducted via fiber optic cables to the recipient.Once there, they are converted back into electrical signals. These light signals can be tapped into on the cables, enabling unauthorized persons to intercept data without detection. However, this does not go undetected if single light particles, photons, are used for encryption based on quantum cryptography….
The situation changed dramatically when a large international team of over 80 astronomers, led by Massachusetts Institute of Technology's Hubble Fellow Michael…
The discovery of this cluster, known as the Phoenix Cluster, made with the National Science Foundation's South Pole Telescope, may force astronomers to rethink…
Sierra Nevada Corporation (SNC) is one of three companies that will receive hundreds of millions of dollars to further develop its commercial human spacecraft…
A National Science Foundation-funded radio telescope in Antarctica has found an extraordinary galaxy cluster that may force astronomers to rethink how galaxy…
A new study by researchers at the University of California, San Diego, and Emory University has uncovered fundamental details about the hexamer structures that…
Living subjects are very complex systems and, at the same time, stunningly robust and accommodative. The secret of success are their proteins which build up…
Experiments using heavy ions at CERN1’s Large Hadron Collider (LHC) are advancing understanding of the primordial Universe. The ALICE, ATLAS and CMS…
They are often only visible to those in flight above a storm, and happen so quickly you might not even see it unless you chance to be looking directly at it….
