Researchers Recreate Space Jets Using Extremely High-Powered Lasers

Streaming jets of high-speed matter produce some of the most stunning objects seen in space. Astronomers have seen them shooting out of young stars just being formed, X-ray binary stars and even the supermassive black holes at the centers of large galaxies.

New Way of Defining Measurement Errors Applicable in Quantum Domain

Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics with the first rigorous formulation supporting the uncertainty principle as Heisenberg envisioned it.

Magnetic Properties Observed in Iron Based Compound Without Rare Earth Elements

Scientists at the Department of Energy's Ames Laboratory have observed magnetic properties typically associated with those observed in rare-earth elements in iron. These properties are observed in a new iron based compound that does not contain rare earth elements, when the iron atom is positioned between two nitrogen atoms.

Lens in the Sky Amplifies Light from Supernova

An exceptionally bright supernova reported in 2013 is so luminous, a new study reports, because a lens in the sky amplified its light. The discovery of the lens settles an important controversy in the field of astronomy.

Galaxy Magnifies Supernova Thirtyfold Through Gravitational Lensing

A team of researchers led by Robert Quimby at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has announced the discovery of a galaxy that magnified a background, Type Ia supernova thirtyfold through gravitational lensing. This is the first example of strong gravitational lensing of a supernova confirms the team's previous explanation for the unusual properties of this supernova.

Researchers Demonstrate How High-Temperature Superconductivity Emerges out of Magnetism

Scientists at SLAC National Accelerator Laboratory and Stanford University have shown for the first time how high-temperature superconductivity emerges out of magnetism in an iron pnictide, a class of materials with great potential for making devices that conduct electricity with 100 percent efficiency.

Coldest Known Brown Dwarf Discovered

NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole.
