恒星

The giant planet is young and hot, but still only 1/100,000th the brightness of its parent star (by comparison, cooler Jupiter is one-billionth the brightness of the sun).

这个巨行星年轻而炎热，但仍旧只有主恒星十万分之一的光芒。

Project content:According to the market demand,expand production of Four-star、and star series bike parts: front shaft、back shaft 、bike pump、front fork、steel ball、chain、chainwheel crank、cold patch glue、glue and other products for all kinds of bikes.

二、项目内容：根据市场需求，扩大生产&佛斯特&、&四星&、&恒星&牌系列自行车中轴、前后轴、飞轮、链条、曲柄、胶水、前叉、钢珠、打气筒等产品。

The brightest star in the nighttime sky, Sirius, or the Dog Star, greatly outshines its white dwarf companion, Sirius B. At 8.6 light-years away, Sirius is the nearest star to Earth.

夜空中最亮的一颗星，天狼星，或者叫&犬狼星&，其光芒远远胜过它的白矮星伴星，在8.6光年外的天狼星是距地球最近的一颗恒星。

But it took the Hubble Space Telescope with a clever device to block out the glaring light of the star itself and see the graceful, elongated band of dust.

但是要观察到它长长的优美的尘埃带只有借助于哈勃望远镜的智能仪器来疲敝掉恒星本身的刺眼强光。

This red cloud, composed of hydrocarbon dust similar to car exhaust, is being blown out into space by the galaxy's millions of young stars.

这个红色云，组成由碳氢化合物粉尘类似于汽车排气管，是吹出来进入太空的银河系的数以百万计的年轻恒星。

The large concentrations of gas and dust in both galaxies may well erupt into regions of active star formation in the near future.

在不久的将来，这些大量集中的气体和灰尘可能向某些能够形成恒星的区域发生巨大的爆发。

Note 2: Previous studies for this star have shown that the abundances of metals such as iron and calcium are about 30 times lower than in the Sun, while the elements heavier than iron are as rich as the Sun's.

注2：先前研究这颗恒星已经表明，银河系中的金属，如铁，钙约有30时报低于太阳，而更重的元素，比铁都是那么富有太阳的。

Note3: Actinide abundance ratios may be applied to measurements of stellar ages.

注3：锕充足比率可用于测量恒星的年龄。

Their discovery marks the first abundance determination of the actinide s element thorium in a star beyond the Milky Way, and follows the detection of thorium in more than ten stars within the Milky Way.

他们发现，标志着首丰测定的锕系元素钍星以外的银河系，跟检测钍十余恒星的银河系。你知道它的英文吗？

Major advances have been made in the last a few years, including the discovery of fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence showing that many GRBs are associated with star-forming regions of the host galaxies and possibly a peculiar type of supernova.

过去几年里γ暴的研究取得了重大突破，包括发现了变暗的X射线、光学和射电余辉，探测到位于宇宙学距离的寄主星系，发现γ暴与恒星形成区成协、甚至可能与超新星关联的证据等等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
