In this picture, which combines views from Hubble and the Keck-II telescope on Hawaii (using adaptive optics), you can see a foreground galaxy that is acting as the gravitational lens. The galaxy resembles how our home galaxy, the Milky Way, would appear if seen edge-on. But around this galaxy there is an almost complete ring — the smeared out image of a star-forming galaxy merger far beyond. (Credit: NASA, ESA)

Probability density of an Efimov trimer state at different three-body geometries that are characterized by the polar angle — indicated by the trimer legends. The key feature in the probability density is that unlike ordinary molecular binding that mostly has a single geometry, the Efimov trimer covers have a broad range of geometries. The atoms in such states behave more like in a fluid drop. (Credit: Yujun Wang, Kansas State University)
Dark matter and dark energy continue to be cosmological conundrum for physicists worldwide. Nobel prize winner Brian Schmidt offers his perspective in an interview.

. A novel class of electronic materials – the so-called transition-metal oxides – hold promise for exciting, new applications. Where layers of this novel class of electronic materials touch, often a unique, and unprecedented phenomenon occurs: for instance, the interface between two insulators can become superconducting, or a strong magnetic order can build up between two non-magnetic layers.
