Experience the Gravity of a Super Earth HD 40307g Poster

Here's a great poster featuring a beautiful image from deep space


tagged with: hd 40307g, nasa, space, art, astronomy, exploration, planet, exoplanet

Twice as big in volume as the Earth, HD 40307g straddles the line between "Super-Earth" and "mini-Neptune" and scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. One thing is certain though: at eight time the Earth's mass, its gravitational pull is much, much stronger.

Your body, the battery: Powering gadgets from human “biofuel”

Science Focus

original post »

Technology has always been intimately linked to the human body. From sharpened flint to smartphones, we've been carrying our inventions for millennia—but the relationship is about to get even closer. The next generation of electronic devices might not just be near our bodies, they could be powered by them.

Staying alive guzzles energy. In order to keep us ticking, our bodies need to burn between 2,000 and 2,500 calories per day, which is conveniently enough to power a modestly used smart phone. So if just a fraction of that energy could be siphoned, our bodies could in theory be used to run any number of electronic devices, from medical implants to electronic contact lenses—all without a battery in sight. Recently, researchers have taken important strides toward unlocking this electric potential.

Untapped potential

To start, the energy in our bodies exists in various forms. Most of them need some manipulation before they can be used to power an electronic device. But not all do.

Monogram, Butterfly Nebula, Scorpius Constellation Classic Round Sticker

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


tagged with: envelope sealers, galaxies and stars, stellar winds, btbgneb, butterfly nebula, bug nebula, scorpius constellation, ngc 6302, sculptured gas clouds, monogram initials

Galaxies, Stars and Nebulae series NGC 6302, more popularly called the Bug Nebula or the Butterfly Nebula, lies within our Milky Way galaxy, roughly 3,800 light-years away in the constellation of Scorpius.
The central dying star cannot be seen because it's hidden within a doughnut-shaped ring of dust, which appears as a dark band pinching the nebula in the centre. The thick dust belt constricts the star's outflow, creating the classic "bipolar" or hourglass shape displayed by some planetary nebulae.
The nebula's reddish outer edges are largely due to light emitted by nitrogen, which marks the coolest gas visible in the picture. The white-coloured regions are areas where light is emitted by sulphur. These are regions where fast-moving gas overtakes and collides with slow-moving gas that left the star at an earlier time, producing shock waves in the gas (the bright white edges on the sides facing the central star).

This is a mosaic image, one of the largest ever taken by NASA's Hubble Space Telescope of the Crab Nebula, a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans.

Emission Nebula NGC 2467 in Constellation Puppis Square Sticker

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


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

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.
