Monogram - Emission Nebula NGC 2467 in Puppis Classic Round Sticker

tagged with: envelope sealers, galaxies and stars, sculptured gas clouds, enebicp, constellation puppis, ngc 2467, the stern, hot young stars, star incubator, monogram initials

Galaxies, Stars and Nebulae series A colourful star-forming region is featured in this stunning image of NGC 2467 located in the southern constellation of Puppis (The Stern). Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing gas. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas, mostly hydrogen, that serves as an incubator for new stars. Some of these youthful stars have emerged from the dense clouds where they were born and now shine brightly, hot and blue in this picture, but many others remain hidden.

Eclipsed in Southern Skies

more »
This stunning panorama in southern skies was recorded on the colorful night of September 27/28 from Carngegie Las Campanas Observatory. A diffuse glow and dark rifts of the central Milky Way hang over domes of the twin 6.5 meter Magellan telescopes. But most eye-catching is the deep red glow of the Moon. Immersed in Earth's shadow during the much anticipated perigee-total-lunar eclipse, the Moon's surface reflects the light of sunsets and sunrises scattered and refracted into the planet's cone-shaped umbra. Along with the dramatic hue of the eclipsed Moon, other colors of that night captured by the sensitive digital camera include the red and green shades of atmospheric airglow. Viewers can also spot the Andromeda Galaxy below the Moon, seen as a tiny smudge through the reddish airglow and lights along the horizon. The Magellanic Clouds, satellite galaxies of the Milky Way, join in at the far left of the full panorama frame.

First observation made of quantum-tunneling diffusion of hydrogen atoms on ice

more »
(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," along the two-dimensional surface of a solid. The most well-known mechanism to explain surface diffusion is a classical mechanism called thermal hopping, in which gas molecules jump from one adsorption site (the place where the gas molecules attach to the surface) to another at a temperature-dependent rate. So far, thermal hopping is the only mechanism known to explain the surface diffusion of hydrogen atoms on the surface of ice.

Quantum dots have made it possible to substantially increase color quality in LCD displays. However, these cadmium-based nanocrystals have proven to be harmful to the environment. Fraunhofer researchers are working together with an industry partner to develop a promising alternative: quantum dots based on indium phosphide.

Scientists' discovery could have powerful effect on electronics

more »
The field of quantum mechanics deals with materials at atomic dimensions, and big discoveries often happen at a very small scale. Researchers in the Erik Jonsson School of Engineering and Computer Science, in collaboration with an international team of engineers and scientists, have uncovered a phenomenon that could have major implications for the development of nano-electronic circuits and devices.

Monogram, Witch Head Nebula deep space image Classic Round Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space

Monogram, Witch Head Nebula deep space image Classic Round Sticker

tagged with: monogram initials, star galaxies, outer space picture, deep space astronomy, witch head nebula, cursing witch, nasa space photograph, faces in space, witches curse, hrbstslr wtchneb, screaming witch

Galaxies, Stars and Nebulae series A witch appears to be screaming out into space in this image from NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE's detectors.
The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.
WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned.

Tarantula Nebula Star Forming Gas Cloud Sculpture Case For The iPad Mini

tagged with: billowing interstellar gas clouds, awesome hubble images, star forming activity, star nurseries, tarantula nebula, triggering star formation, large magellanic cloud, hrbstslr tnlmcsfr, cosmological, galaxies, young hot stars

Galaxies, Stars and Nebulae series An awesome mobile phone shell featuring the Tarantula Nebula of the Large Magellanic Cloud, which is the nearest galaxy to the Milky Way, our galactic home. This Hubble image shows old stars from the distant past and rich, interstellar gas clouds feeding the formation of new ones. The most massive and hottest stars are intense, high-energy radiation sources and this pushes away what remains of the gas and dust, compressing and sculpting it. As the whorls and eddies clump and stretch it, gravity takes over and the birth of the next generation of new stars is triggered.
