恒星年

This conclusion was seemingly bolstered in 1999 when Hubble failed to find close-orbiting "hot Jupiter"-type planets around the stars of the globular cluster 47 Tucanae.

这一结论在1999年似乎得到支持，因为当时&哈勃&没能在图坎尼47号球状星团中发现任何紧密围绕恒星运转的类似于&高温木星&的行星。

In Egypt there exists a star clock for the Precession of the Equinoxes and an electric light bulb that dates to 2600 BC.

在埃及存在岁差的恒星时钟和日期是西元前2600年的电灯泡。

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。

Scheduled to begin operations in 2018, the E-ELT will help track down Earth-like planets around other stars in the "habitable zones" where life could exist — one of the Holy Grails of modern observational astronomy.

E-ELT预定在2018年开始科学操作，将获取其他恒星周围生命可能存在的&宜居带&中类地行星的图像——现代天文学的圣杯之一。

Orbiting a Red Dwarf Star Image of the Day Gallery Orbiting a Red Dwarf Star This artist's concept of a gas giant planet orbiting a red dwarf K star shows a planet has not been directly imaged , but its presence was detected in 2003 microlensing observations of a field star in our galaxy .

此图本意是拍摄一颗环绕红矮星K运行的由气体组成的巨大行星，但并未直接对其成像，不过该行星的踪迹在2003年针对银河系中恒星带的引力透镜现象进行观测时被发现。

For centuries, astronomers had not been able to figure out the nature of this "eclipsing binary system," in which a bright naked-eye star is eclipsed by a companion object every 27 years.

一个多世纪来，天文学家一直没搞清柱一&食双星&的性质，这颗肉眼可见明亮恒星，以27年的周期改变光度。

However, one third of these stars show an unexplained additional periodic variation, on even longer timescales — up to five years.

但是，1/3的类太阳恒星显示出一种难以解释的附加的周期性光度变化，其时间甚至长达5年。

The most massive of these young stars race through their evolution in a few million years and explode as supernovas.

质量最大的年轻恒星会在几百万年的时间里飞快地演化完毕，并以超新星的形式爆发。

Since the improvement of the observation, especially at high redshift and the advancement in the nuclesynthesis in the star, more and more people pay close attention to this field.

近十年来由于观测手段，尤其是对高红移的观测手段的提高，以及在恒星核合成研究方面取得的新进展使得此领域再次为人们关注。

Batista and John Cena were two of the brightest stars in WWE at the beginning of 2005, so it was no wonder that they were the final two Superstars in the Royal Rumble that year.

巴蒂斯塔和约翰价格两方面的最亮的恒星则WWE在2005年初，所以说这是怪不得说，他们最后两名超级巨星在皇家隆隆这一年。

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

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
