Earth's Magnetic Field Far Older than Believed

Earth's Magnetic Field Far Older than Believed

Since 2010, the best estimate of the age of Earth's magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older. [More]
Intense Winds from Hot Stars and Energetic Star Formation fill the Lagoon Nebula

Intense Winds from Hot Stars and Energetic Star Formation fill the Lagoon Nebula

Some of the most breathtaking views in the Universe are created by nebulae - hot, glowing clouds of gas. This new NASA/ESA Hubble Space Telescope image shows the centre of the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust. [More]
Gravitational Microlensing Helps Discover Exoplanet Orbiting far from its Central Star

Gravitational Microlensing Helps Discover Exoplanet Orbiting far from its Central Star

NASA's Hubble Space Telescope and the W.M. Keck Observatory in Hawaii have made independent confirmations of an exoplanet orbiting far from its central star. The planet was discovered through a technique called gravitational microlensing. [More]
Comet Churyumov-Gerasimenko’s Near Surface Material May Have Changed Since its Formation

Comet Churyumov-Gerasimenko’s Near Surface Material May Have Changed Since its Formation

Comet Churyumov-Gerasimenko poses new riddles: Surface material measurements performed by the «Philae» landing module indicate that the near surface material might have changed since its formation. Up to now, many researchers had assumed that it has remained in virtually the same state since its formation about 4.5 billion years ago. The results of the study, in which researchers from the University of Bern were also involved, have been published in «Science» magazine. [More]
Astronomers Discover Secret Planetary System Hiding in the Arms of Cassiopea

Astronomers Discover Secret Planetary System Hiding in the Arms of Cassiopea

Astronomers from the University of Geneva (UNIGE) and members of the NCCR PlanetS have teased out a secret planetary system hiding in the arms of Cassiopea, just 21 light years away from us. The remarkable system, named HD219134, hosts one outer giant planet and three inner super-Earths, one of which transits in front of the star. [More]
Novel Method for Gaining Insight into Mechanical Systems Behavior at Classical-Quantum World Interface

Novel Method for Gaining Insight into Mechanical Systems Behavior at Classical-Quantum World Interface

Scientists at Freie Universität Berlin in the group of physics professor Jens Eisert developed a novel method for gaining insight into the complex behavior of mechanical systems at the micro and nano scale. These systems are located at the interface of the physical worlds that, on the one hand, are described by classical mechanics, and on the other, by quantum theory, i.e., the theory of the behavior of atoms, molecules, and modes of light.

Astronomers Detect Lithium Ejected by Nova Centauri 2013

Astronomers Detect Lithium Ejected by Nova Centauri 2013

The chemical element lithium has been found for the first time in material ejected by a nova. Observations of Nova Centauri 2013 made using telescopes at ESO's La Silla Observatory, and near Santiago in Chile, help to explain the mystery of why many young stars seem to have more of this chemical element than expected.

Physicists Develop Fully-Symmetric Formulation of Quantum Theory

Physicists Develop Fully-Symmetric Formulation of Quantum Theory

Theoretical physicists at the Université libre de Bruxelles have developed a fully-symmetric formulation of quantum theory which establishes an exact link between asymmetry and the fact that we can remember the past but not the future... [More]
Cornell Physicists Develop Quantum-Compatible Mechanical Resonators

Cornell Physicists Develop Quantum-Compatible Mechanical Resonators

In their quest to make the world's most precise sensors, Cornell physicists have developed a novel method of manipulating mechanical resonators to be sensitive enough to work at the quantum scale. [More]
Astronomers Discover Aurora from Low-Mass Star

Astronomers Discover Aurora from Low-Mass Star

Astronomers have discovered the first aurora ever seen in an object beyond our Solar System. The aurora -- similar to the famous "Northern Lights" on Earth -- is 10,000 times more powerful than any previously seen. They found the aurora not from a planet, but from a low-mass star at the boundary between stars and brown dwarfs. [More]
