Small thunderstorms may add up to massive cyclones on Saturn

more »
Atmospheric scientists propose a possible mechanism for Saturn's polar cyclones: Over time, small, short-lived thunderstorms across the planet may build up angular momentum, or spin, within the atmosphere -- ultimately stirring up a massive and long-lasting vortex at the poles.

Philae wake-up triggers intense planning

more »

The receipt of signals from Rosetta’s Philae lander on 13 June after 211 days of hibernation marked the start of intense activity. In coordination with its mission partners, ESA teams are working to juggle Rosetta’s flight plan to help with renewed lander science investigations.

Unveiling the ancient climate of Mars

The high seas of Mars may never have existed. According to a new study that looks at two opposite climate scenarios of early Mars, a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the planet today.

World's thinnest lightbulb -- graphene gets bright

more »
Scientists have demonstrated -- for the first time -- an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament. They attached small strips of graphene to metal electrodes, suspended the strips above the substrate, and passed a current through the filaments to cause them to heat up.

Nanotubes ground to nanoribbons

Researchers on three continents have discovered that functionalized carbon nanotubes, when ground together, react and unzip into nanoribbons. The all solid-state process suggests that nanostructures may serve as templates for controlled chemical reactions.

Eagle Nebula Print

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

This eerie, dark structure in IC 4703 (the Eagle nebula) is a column of cool molecular hydrogen gas and dust that is an incubator for new stars. The stars are embedded inside finger-like protrusions clearly seen extending from the top of the column. Each "fingertip" is somewhat larger than our own solar system. The pillar is slowly eroding away by the ultraviolet light from nearby hot stars, a process called "photoevaporation". As it does, small globules of especially dense gas buried within the cloud are uncovered. These globules have been dubbed "EGGs" ; an acronym for "Evaporating Gaseous Globules". The shadows of the EGGs protect gas behind them, resulting in the finger-like structures at the top of the cloud.

Idaho Republicans want Bible in schools for “astronomy, biology, geology”

Science Focus

original post »

Yesterday, we described how legislation in Louisiana may be encouraging teachers to introduce religious material in science classes. But Louisiana is clearly not alone in recommending that its educators engage in constitutionally forbidden activities. Later that day, we were directed to a document suggesting that problems could be brewing in Idaho.

The document is a set of proposed resolutions crafted by the state Republican Party's Central Committee. Among those is Resolution 2015-P20, "A Resolution Supporting Bible Use in Idaho Public Schools." While the Bible could add value to a number of curricula (social studies, literature, and comparative religion, for example, all of which are named in the resolution), it's not widely recognized for being much help with plate tectonics. Yet the resolution also suggests that the Bible should be used in classes on astronomy, biology, geology, world geography, archaeology, music, and sociology. Somehow, chemistry and physics escaped the committee's notice.

While a resolution like this is a long way from becoming law, the Republican Party holds the governorship and large majorities in both houses of the legislature, so there is a heightened risk.

Tarantula Nebula Star Forming Gas Cloud Sculpture Star Sticker

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


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

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.

Star Birth in Constellation Cygnus, The Swan Star Sticker

Galaxies, Stars and Nebulae series A gorgeous star forming region in Constellation Cygnus (The Swan). This Hubble image shows a dust-rich, interstellar gas cloud with a new-born star in the centre of the hour-glass shape. The glowing blue of the hydrogen in this nebula is due to the jets being emitted from the forming star as dust falls into into it and this causes the heating and turbulence of the hydrogen. The star, known as S106 IR, is reaching the end of its birth and will soon enter the much quieter period of adulthood known as the main stage.
