SOFIA to Study Celestial Objects Taking Advantage of Southern Hemisphere's Orientation

NASA's SOFIA airborne observatory will be based in New Zealand for the next two weeks, taking advantage of the Southern Hemisphere's orientation to study celestial objects that are difficult or impossible to see in the northern sky.

Planets Orbiting Cool Stars May be Warmer and Less Icy

In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star’s light with ice and snow on the planet’s surface.

Measurements of Rarest Measureable Processes in Physics to be Presented at EPS-HEP Conference

New results to be presented at the EPS-HEP conference in Stockholm, Sweden, this afternoon have put the Standard Model of particle physics to one of its most stringent tests to date. The CMS and LHCb experiments at CERN’s Large Hadron Collider will present measurements of one of the rarest measureable processes in physics: the decay of a Bs (pronounced B-sub-s) particle into two muons.

More Elegant Way to Fine-Tune Topological Insulator Behavior

Physicists at the University of Michigan say they have devised a more elegant way to fine-tune the behavior of topological insulators—peculiar, two-faced materials whose electrical properties differ markedly between their surface and their interior.

Hubble Helps Track Orbital Motion of 33,000 Stars in Old Globular Cluster

UBC astronomers have used NASA’s Hubble Space Telescope to track the orbital motion of 33,000 stars in one of the galaxy’s oldest globular clusters, offering new insights into the formation of the Milky Way.

Snow Line Imaged in Far-Off Infant Planetary System

A snow line has been imaged in a far-off infant planetary system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System. The results are published today in Science Express.

Movement of Stars in Globular Clusters Linked With Stars' Ages

Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in an ancient globular star cluster, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days.
