暗物质

These so-called dark stars, named for the song "Dark Star" by the Grateful Dead , would contain mostly normal matter, in the form of hydrogen and helium molecules, but would be vastly larger (about 400 to 200,000 times wider) and "fluffier" than the sun and other stars.

这些所谓的暗恒星，是根据&感恩而死&乐队创作的歌曲《暗恒星》命名的。暗恒星中所包含的主要是普通物质，以氢分子和氦分子的形式而存在。但是暗恒星比太阳和其他恒星要大得多（大400倍至20万倍），密度也要低得多。

The study of solar filament activations and eruptions is important not only in understanding formation, supporting and stability of filaments in general, but also in understanding violent solar eruptions such as flares and coronal mass ejections.

太阳暗条激活与爆发的研究，不仅对理解暗条的形成、支撑和稳定性是重要的，对理解剧烈的太阳爆发，如耀斑和日冕物质抛射，也是重要的。

"While this result is consistent with dark matter, it is also consistent with backgrounds," said Fermilab Director Pier Oddone. In 2010, the collaboration is installing an upgraded detector at Soudan with three times the mass and lower backgrounds than the present detectors.

&尽管这次的结果跟暗物质一致，它同时也跟背景一致，&费米实验室的主任Pier Oddone说道：在2010年，研究者们将会在Soudan安装一个升级了的探测器(超级CDMS，SuperCDMS)，比现在的探测器重3倍，而噪音水平更低。

"This is a story that may soon be at its end," Turner said, noting that the Cryogenic Dark Matter Search in the Soudan mine of Minnesota and other experiments below the ground should be sensitive enough to detect a WIMP.

特纳注意到明尼苏达州苏丹矿山里的低温暗物质搜寻计划及其他的地下试验非常精确灵敏，应该可以探测到弱作用重粒子，他说：情况可能很快就会有结果的。

The other was the announcement earlier in the week that scientists have found direct evidence for dark matter.

另一个是在本周初科学家已经发现暗物质的直接证据的发表。

另一个本周早期宣布的是科学家们发现了暗物质存在的直接证据。

Meanwhile Pierre Colin of the Max Planck Institute for Physics in Munich and his colleagues reckon that the shadow of the moon could be used to help work out whether the abundance of positrons actually does come from annihilating dark matter, using telescopes that look for Cherenkov radiation —flashes of light in the sky—that are created when cosmic rays, in the form of high-energy electrons and positrons, hit the upper atmosphere.

同时，在慕尼黑的马普物理研究所的皮埃尔·科林和他的同事们指出：可以用望远镜观测月球阴影下的切伦科夫辐射现象来判断大量的正电子是否的确来自湮灭的暗物质。切伦科夫辐射现象，是指带有高能量的电子和正电子的宇宙射线，撞击外层大气层时在天空中产生的闪光现象。

At near-absolute zero, conducting research is "quite challenging," said Gaitskell, who spent a decade trying to make detection systems work at that temperature.

盖茨凯尔没有参与亚巴塞斯的研究。他说，在接近绝对零度的条件下实施研究&非常具有挑战性&。盖茨凯尔曾花费十年心血，试图开发出能在此温度下运转的暗物质探测系统。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
