Great Rift Near the Center of the Milky Way
more »
Over 100 telescopic image panels in this stunning vertical mosaic span about 50 degrees across the night sky. They follow part of the Great Rift, the dark river of dust and molecular gas that stretches along the plane of our Milky Way Galaxy. Start at top center and you can follow the galactic equator down through brighter stars in constellations Aquila, Serpens Cauda, and Scutum. At the bottom is Sagittarius near the center of the Milky Way. Along the way you'll encounter many obscuring dark nebulae hundreds of light-years distant flanked by bands of Milky Way starlight, and the telltale reddish glow of starforming regions. Notable Messier objects include The Eagle (M16) and Omega (M17) nebulae, the Sagittarius Star Cloud (M24), the beautiful Trifid (M20) and the deep Lagoon (M8). Tomorrow's picture: pixels in space

Comet Chury is much younger than previously thought
more »
Based on computer simulations, astrophysicists conclude that the comet Chury did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.

Skin pigment could help strengthen foams, fabrics
more »
Melanin is the natural molecule in animals' skin, hair and the iris of eyes that gives them color and helps protect them from ultraviolet light. Someday soon, the pigment could be found in unexpected places such as sofa cushions or clothing -- but not for its hue. Scientists have found that adding a small amount of melanin to polyurethane makes it far stronger than the material by itself.

The thinnest photodetector in the world
more »
The world's thinnest photodetector has been developed. This is a device that converts light into an electric current. With a thickness of just 1.3 nanometers - 10 times smaller than the current standard silicon diodes - this device could be used in the Internet of Things, smart devices, wearable electronics and photoelectronics. This 2D technology uses molybdenum disulfide (MoS2) sandwiched in graphene.

Graphene templates used to make new metal-oxide nanostructures

Researchers have found a new method for making ultrathin metal-oxide sheets containing intricate wrinkle and crumple patterns. In a new study, the researchers show that the textured metal-oxide films have better performance when used as photocatalysts and as battery electrodes.
