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…
Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the…
The new Willard L. Eccles Observatory’s 32-inch reflecting telescope took its first pictures the night of Oct. 15. The “first light” photo is an edge-on view…
Heinke and a colleague have identified the 20 kilometre-wide remnant of the supernova as a neutron star. It's the youngest neutron star ever identified, and…
This will be the third Earth swingby, the last of Rosetta’s four planetary gravity assists. Closest approach to Earth is expected at 08:45 CET (07:45 UT). The…
The discovery has just been published by the journal Nature. The study reports that researchers using the VERITAS array of four telescopes at the Fred Lawrence…
The gamma rays observed by the team have energies more than a trillion times higher than the energy of visible light and are the highest-energy photons ever…
“Starburst galaxies have not been accessible in gamma rays before,” said Fermi team member Seth Digel, a physicist at SLAC National Accelerator Laboratory in…
The measurement of biological magnetic fields relies mostly on SQUID technology. However, the high level of running cost (for cooling) and the complex…
The experiment was performed by a team that includes astrophysicists at Penn State University, who used NASA's Fermi Gamma Ray Space Telescope to study…
Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves…
Using the invention, virtually no force is exerted on the abrasive layer during a dressing process. Combined with the small dimensions of the wire electrode…
Computer scientists at the University of Washington have used Android, the open-source mobile operating system championed by Google, to turn a cell phone into…
Named RICC (RIKEN Integrated Cluster of Clusters), the supercomputer is made up of four distinct computer clusters connected through InfiniBand…
Cellular phones – once a luxury used strictly for talking – have taken on many new roles in recent years. Now researchers at Saint Louis University and Old…
The system works well, and millions rely on it every day, but what tells the GPS satellites where they are in the first place? “For GPS to work, the orbital…
Suggesting that atoms in a solid can move or be transported through it seems as impossible as using a syringe to inject material into a billiard ball. It…
