Locked within the cometary particles is unique chemical and physical information that could be the record of the formation of the planets and the materials from which they were made, he adds.

彗星微粒中封存着独特的化学和物理信息，或许可以记录行星和和彗星成分物质的形成，他补充说。

Less than a year after arriving on Earth the Stardust cometary samples have both challenged and confirmed scientists' most basic assumptions on the nature of comets, the history of the solar system, and the origins of life on Earth.

Methods Vero cells were cultured with mercury chloride, at the same time zinc sulfate, sodium selenite and zinc sulfate together with sodium selenite were added respectively. The tail length and the rate of the comet cells were measured and calculated.

常规培养vero细胞，通过MTT法制定出氯化汞染毒剂量，与氯化汞同时加入不同浓度的硫酸锌、亚硒酸钠以及硫酸锌+亚硒酸钠溶液，共同培养2 h后采用单细胞凝胶电泳法检测细胞的彗星尾长和彗星率。

Several days before Comet 73P shot across the Ring Nebula,astro-paparazzi Nicolas Outters caught the comet sneaking past M13, the Great Globular cluster in Hercules.

There has also been speculation - but scant evidence - that a brilliant comet seen in 372 BC, which the Greek philosopher Ephorus claimed to have seen tear in two, was perhaps the progenitor of the entire Kreutz system.

As Comet Lulin moves into the northern sky in mid February to rise around midnight, it should at least be spotted by comet watchers with binoculars and a good sky chart.

彗星卢琳在2月中旬将移动到北变的天空，午夜中升起，彗星了望者用双目望眼镜和天体图应该就能将它定位。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
