Thanks to Neil DeGrasse Tyson all of my astronomy books are useless! This poster is available with or without labels and is suitable for classroom displays. Order yours and try to come up with a new mnemonic device now that Aunt Sally has no Pizza.

Physicists spy on random motion of electrons with defective diamonds

Science Focus

original post »

Normally, noise is something we scientists try to avoid. In the most advanced physics experiments, the goal is usually to measure something new. If you ever ask the experimenters why it took them so long to do a measurement, the most common answer is "finding a way to defeat the noise."

Sometimes, though, the noise becomes more interesting than the signal, telling us new things about the physical system we are studying. The study of noise is not new, of course, but with our increasingly precise control of quantum systems, we can study it in ever finer detail.

In this case, researchers studied Johnson noise, otherwise known as white noise. In a metal, there is a sea of electrons that is free to travel around in constant motion—the fact that the temperature is above absolute zero is enough to keep electrons in motion. Because of this motion, the density of electrons varies slightly from place to place at any given time. These fluctuations create small attractive and repulsive forces that drive electrons to attempt to neutralize the fields. In doing so, they create new density fluctuations and fields in an endlessly repeating cycle.

Monogram, Butterfly Nebula, Scorpius Constellation 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).

M51: The Whirlpool Galaxy

more »
Follow the handle of the Big Dipper away from the dipper's bowl until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (right), NGC 5195. The pair are about 31 million light-years distant and officially lie within the angular boundaries of the small constellation Canes Venatici. Though M51 looks faint and fuzzy to the eye, deep images like this one can reveal striking colors and the faint tidal debris around the smaller galaxy

Where the Grass is Always Redder on the Other Side Print

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


tagged with: kepler-186f, planet, 'habitable, nasa, space, star, astronomy, solar

Kepler-186f is the first Earth-size planet discovered in the potentially 'habitable zone' around another star, where liquid water could exist on the planet's surface. Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star's red-wavelength photons, making for a color palette that's very different than the greens on Earth. This discovery was made by Kepler, NASA's planet hunting telescope.

Monogram - Emission Nebula NGC 2467 in Puppis Round Stickers

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, 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.
