Plasmonic metamaterials: From microscopes to invisibility cloaks

(PhysOrg.com) -- A new class of artificial materials called metamaterials -- which derive their properties from carefully engineered, nanostructured building blocks rather than from their chemical composition -- may one day ...

A multilayer haze system on Saturn's hexagon

A rich variety of meteorological phenomena takes place in the extensive hydrogen atmosphere of Saturn, a world about 10 times the size of the Earth. They help us to better understand similar features in the Earth's atmosphere. ...

Solar wind from the center of the Earth

High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University ...

New ultra metal-poor star discovered

An international team of astronomers has detected a new ultra metal-poor star with the lowest ever measured abundance of iron. Designated SMSS J160540.18−144323.1, the newly found object is the most iron-deficient star ...

A warp in the Milky Way linked to galactic collision

When most of us picture the shape of the Milky Way, the galaxy that contains our own sun and hundreds of billions of other stars, we think of a central mass surrounded by a flat disc of stars that spiral around it. However, ...
