Researchers develop world's thinnest electric generator

more »

Researchers have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide, resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.

Getting to know super-earths: Astronomers conduct atmospheric study of a second super-Earth

"If you have a coin and flip it just once, what does that tell you about the odds of heads versus tails?" asks Heather Knutson, assistant professor of planetary science at Caltech. "It tells you almost nothing. It's the same with planetary systems," she says.

The personality types of successful poker players, according to science

Science Focus

original post »


Sure, you've got to know when to hold 'em, and know when to fold 'em.

But more importantly, you need to have the emotional temperament to follow through on that strategy, even when the stakes are high and the pressure is on.

That's the conclusion of a newly published study that examines the personality types of successful poker players. Confirming the cliché, it finds such people tend to be cool, calm, and difficult to rattle.

Writing in the journal Cyberpsychology, Behavior and Social Networking, a research team led by the University of Helsinki's Michael Laakasuo suggests such steadiness...

Atmospheric oxygen can be created without plant life

Science Focus

original post »

Over the past 40 years, evidence has turned up on Mars pointing to the presence of oxygen. This suggested that some oxygen must have been created in the early Earth’s atmosphere as well, due to the similar compositions of the two atmospheres. Before this new idea, it was widely understood that oxygen in the Earth’s atmosphere originated in an event called the “Great Oxidation Event,” which occurred about 2.4 billion years ago as the first plants appeared and converted carbon dioxide to oxygen.

But a new experiment has confirmed that there is a mechanism for creating oxygen that doesn't require the presence of life. The results have implications not only for understanding the evolution of Earth’s atmosphere, but also for the study of exoplanetary atmospheres.

The experiment

The team used a vacuum ultraviolet (VUV) laser to break carbon dioxide apart, leaving free carbon and oxygen. Vacuum ultraviolet has a short wavelength (a range of 200-10 nanometers) that puts it at the far end of the ultraviolet portion of the electromagnetic spectrum. Today, VUV is absorbed by the oxygen in the atmosphere (hence its name). But in the early atmosphere, VUV from the Sun could have been producing oxygen out of then-abundant carbon dioxide.

Name, Star Superbubble in Large Magellanic Cloud Gift Wrapping Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!


tagged with: dust clouds, new born stars, star nursery, interstellar hydrogen clouds, n44 nebula, star cluster ngc 1929, supernovas, hrbstslr sbsblmc, astronomy images, outer space, hot young stars

Galaxies, Stars and Nebulae series An awesome photograph from deep space featuring a super bubble in the Large Magellanic Cloud, which is a small satellite of our Milky Way galaxy around 160000 light years from us.
The massive stars of this nebula produce intense radiation, expelling matter at high speeds, and race through their main stage finally to explode as supernovas. The stellar winds of charged hydrogen and other particles and the supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. Blue shows hot regions created by these winds and shocks, while red shows where the dust and cooler gas are found. Yellow regions show where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

Construction secrets of a galactic metropolis

more »

Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood. The Spiderweb Galaxy (formally known as MRC 1138-262) and its surroundings have been studied for twenty years, using ESO and other telescopes, and is thought to be one of the best examples of a protocluster in the process of assembly, more than ten billion years ago.

Monogram Barred Spiral Galaxy NGC 1672 iPad Folio Case

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: monogram initials, star galaxies, deep space astronomy, barred spiral galaxy, starry space picture, galactic arms, supermassive black hole, dust lanes, star forming galaxy, hrbstslr bsgsst

Galaxies, Stars and Nebulae series This NASA Hubble Space Telescope view of the nearby barred spiral galaxy NGC 1672 unveils details in the galaxy's star-forming clouds and dark bands of interstellar dust.
One of the most striking features is the dust lanes that extend away from the nucleus and follow the inner edges of the galaxy's spiral arms. Clusters of hot young blue stars form along the spiral arms and ionize surrounding clouds of hydrogen gas that glow red. Delicate curtains of dust partially obscure and redden the light of the stars behind them by scattering blue light.
Galaxies lying behind NGC 1672 give the illusion they are embedded in the foreground galaxy, even though they are really much farther away. They also appear reddened as they shine through NGC 1672's dust. A few bright foreground stars inside our own Milky Way Galaxy appear in the image as bright and diamond-like objects.
As a prototypical barred spiral galaxy, NGC 1672 differs from normal spiral galaxies, in that the arms do not twist all the way into the center. Instead, they are attached to the two ends of a straight bar of stars enclosing the nucleus. Viewed nearly face on, NGC 1672 shows intense star formation regions especially off in the ends of its central bar.
Astronomers believe that barred spirals have a unique mechanism that channels gas from the disk inward towards the nucleus. This allows the bar portion of the galaxy to serve as an area of new star generation.
NGC 1672 is also classified as a Seyfert galaxy. Seyferts are a subset of galaxies with active nuclei. The energy output of these nuclei can sometimes outshine their host galaxies. This activity is powered by accretion onto supermassive black holes.
NGC 1672 is more than 60 million light-years away in the direction of the southern constellation Dorado. These observations of NGC 1672 were taken with Hubble's Advanced Camera for Surveys in August of 2005. The composite image was made by using filters that isolate light from the blue, green, and infrared portions of the spectrum, as well as emission from ionized hydrogen.

Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.

Rediscovering Venus to find faraway Earths: Measuring gravitational pull of a planet should speed search

more »

As the search for Earth-like planets wages on, a team of researchers may have found a way to speed up the process. The team is developing a new laser-based technology known as the green astro-comb to obtain information about the mass of a distant planet. Using this information, astronomers will be able to determine whether distant exoplanets are rocky worlds like Earth or less dense gas giants like Jupiter.
