Probing Galaxy's Halo Provides New Insights into Galaxy's Formation, Evolution, and Composition

Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored.

Theorists Propose New Method of Amplifying Power of Vacuum Fluctuations

Vacuum is not as empty as one might think. In fact, empty space is a bubbling soup of various virtual particles popping in and out of existence – a phenomenon called "vacuum fluctuations". Usually, such extremely short-lived particles remain completely unnoticed, but in certain cases vacuum forces can have a measurable effect.

The SuperCDMS-SNOLAB Project Selected to Search for Dark Matter

The SuperCDMS-SNOLAB project has been selected by U.S. funding agencies in the second generation (G2) program to search for “dark matter.” This means that the SuperCDMS experiment will be expanding to SNOLAB, Canada’s underground science laboratory specializing in neutrino and dark matter physics in Sudbury, Ontario.

Study Results Offer Clue to Why Superconductivity Doesn’t Happen at Higher Temperatures

A team at Cornell and Brookhaven National Laboratory has discovered that previously observed density waves that seem to suppress superconductivity are linked to an electronic “broken symmetry,” offering an important clue to why superconductivity doesn’t happen at higher temperatures.

Novel Mechanism for How to Make Universal Topological Quantum Computers

So far it exists mainly in theory, but if invented, the large-scale quantum computer would change computing forever. Rather than the classical data-encoding method using binary digits, a quantum computer would process information millions of times faster through the use of quantum states of matter.

Transiting Exoplanet with Longest Known Year Discovered

Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods.
