Experiment attempts to snare a dark energy 'chameleon'

more »
Is dark energy hard to detect because it's hiding from us? According to a recent theory, hypothetical particles called chameleons vary in mass depending on nearby matter: in the vacuum of space, they have a small mass and large reach, pushing space apart. In the lab, surrounded by matter, they have a large mass and small reach, making them difficult to detect. A new experiment seeks to find chameleons by lessening the screening.

New record temperature for a superconductor

Science Focus

original post »

Superconductivity was first seen in metals cooled down to close to absolute zero. But after exhausting every metal on the periodic table, the critical temperature at which the metal transitions to superconductivity never budged far from those extremely low temperatures.

That changed dramatically with the development of cuprate superconductors, copper-containing ceramics that could superconduct in liquid nitrogen—still very cold (138K or −135°C), but relatively easy to achieve. But progress has stalled, in part because we don't have a solid theory to explain superconductivity in these materials.

Now, taking advantage of the fact that we do understand what's going on in superconducting metals, a German research team has reached a new record critical temperature: 203K, or -70°C, a temperature that is sometimes seen in polar regions. The material they used, however, isn't a metal that appears on the periodic table. In fact, they're not even positive they know what the material is, just that it forms from hydrogen sulfide at extreme pressures.

The Rose Galaxies, Arp 273 Square Sticker

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


tagged with: envelope sealers, trgarp, breathtaking hubble space photos, rose galaxy, interacting spiral galaxies, amazing astronomy images, arp 273, star forming activity, new born stars, star nursery, hot young stars

Galaxies, Stars and Nebulae series An amazing outer space picture featuring two interacting galaxies that together form the shape of a rose. The larger of the spiral galaxies, UGC 1810, has a disk that is twisted by the gravitational pull of its companion galaxy, UGC 1813.
Knots of young, hot blue stars bejewel the spirals arms in glistening starlight while below, its smaller, nearly edge-on companion is going through intense star formation at its centre, perhaps triggered by their encounter.

M27: Not a Comet

more »
While hunting for comets in the skies above 18th century France, astronomer Charles Messier diligently kept a list of the things he encountered that were definitely not comets. This is number 27 on his now famous not-a-comet list. In fact, 21st century astronomers would identify it as a planetary nebula, but it's not a planet either, even though it may appear round and planet-like in a small telescope. Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core. The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light. Known by the popular name of the Dumbbell Nebula, the beautifully symmetric interstellar gas cloud is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula. This impressive color composite highlights details within the well-studied central region and fainter, seldom imaged features in the nebula's outer halo. It incorporates broad and narrowband images recorded using filters sensitive to emission from sulfur, hydrogen and oxygen atoms.

Large Magellanic Cloud Superbubble in Nebula N44 Wall Stickers

Here's a great wall decal featuring a beautiful image from deep space


tagged with: awesome astronomy images, interstellar hydrogen clouds, sbsblmc, n44 nebula, star cluster ngc 1929, supernovas, dust clouds, superbubble, star nursery, new born 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.
