Yutu on a Little Planet

more »
Tracks lead to a small robot perched near the top of this bright little planet. Of course, the planet is really the Moon. The robot is the desk-sized Yutu rover, leaving its looming Chang'e 3 lander after a after a mid-December 2013 touch down in the northern Mare Imbrium. The little planet projection is a digitally warped and stitched mosaic of images from the lander's terrain camera covering 360 by 180 degrees. Ultimately traveling over 100 meters, Yutu came to a halt in January 2014. The lander's instruments are still working though, after more than two years on the lunar surface. Meanwhile, an interactive panoramic version of this little planet is available here.

Graphene leans on glass to advance electronics

more »
Scientists have developed a simple and powerful method for creating resilient, customized, and high-performing graphene: layering it on top of common glass. This scalable and inexpensive process helps pave the way for a new class of microelectronic and optoelectronic devices -- everything from efficient solar cells to touch screens.

A metal that behaves like water

more »
Researchers have made a breakthrough in our understanding of graphene's basic properties, observing for the first time electrons in a metal behaving like a fluid. This research could lead to novel thermoelectric devices as well as provide a model system to explore exotic phenomena like black holes and high-energy plasmas.

Silicon chip with integrated laser: Light from a nanowire

more »
Physicists have developed a nanolaser, a thousand times thinner than a human hair. Thanks to an ingenious process, the nanowire lasers grow right on a silicon chip, making it possible to produce high-performance photonic components cost-effectively. This will pave the way for fast and efficient data processing with light in the future.

Twisted X-rays unravel the complexity of helical structures

more »
Since the discovery of the diffraction of X-rays by crystals just over 100 years ago, X-ray diffraction as a method of structure determination has dominated structural research in materials science and biology. However, many of the most important materials whose structures remain unknown do not readily crystallize as three-dimensional periodic structures.

Graphene decharging and molecular shielding

more »
A new study sheds light on unique property of 2-D materials -- ability to shield chemical interactions at the molecular level. Discovery of shielding effect allows scientists to control reactivity of molecules, tune activity of catalysts, and construct new generation of carbon materials.

The sleeping giant NGC 4889 harbors a dark secret

more »
The placid appearance of NGC 4889 can fool the unsuspecting observer. But the elliptical galaxy, seen in a new image from the NASA/ESA Hubble Space Telescope, harbors a dark secret. At its heart lurks one of the most massive black holes ever discovered.

A star's moment in the spotlight

more »
A newly formed star lights up the surrounding clouds in this new image from ESO's La Silla Observatory in Chile. Dust particles in the vast clouds that surround the star HD 97300 diffuse its light, like a car headlight in enveloping fog, and create the reflection nebula IC 2631. Although HD 97300 is in the spotlight for now, the very dust that makes it so hard to miss heralds the birth of additional future stars.

Scientists discover hidden galaxies behind the Milky Way

more »
Hundreds of hidden nearby galaxies have been studied for the first time, shedding light on a mysterious gravitational anomaly dubbed the Great Attractor. Despite being just 250 million light years from Earth, the new galaxies had been hidden from view until now by our own galaxy, the Milky Way. Using CSIRO's Parkes radio telescope equipped with an innovative receiver, an international team of scientists were able to see through the Milky Way, into a previously unexplored region of space.
