恒星

In this sharp composite from the Hubble Space Telescope, Fomalhaut's surrounding ring of dusty debris is imaged in detail, with overwhelming glare from the star masked by an occulting disk in the camera's coronagraph.

在这幅来自哈勃空间望远镜的精细合成图像中，北落师门周围的尘埃环的碎片能够精细展现，并且在相机的日冕观测仪下，能够观测到被一神秘圆盘遮蔽的恒星发出十分耀眼的光线。

The coronagraph has been used to block the light from the brightstar allowing the search for the dim glow of the planet HR 8799b.

通过星冕仪技术，明亮的恒星光全部被遮蔽，以便我们寻找行星HR 8799b的微弱光芒。

The coronagraph has been used to block the light from the brightstar allowing the search for the dim glow of the planetHR 8799b.

通过星冕仪技术，明亮的恒星光全部被遮蔽，以便我们寻找行星HR 8799b的微弱光芒（PS：我们在Photoshop中可以做类似操作，把中央区域给全部dell后，整个图片的亮度、对比度等都会有巨大改变，继续做大幅度增加亮度、对比度操作，有近似的效果——译注）。

Astronomers have partially solved the problem of looking at objects near to a star's bright glare by inventing the coronagraph, which focuses all the incoming light around a dark spot in the telescope's innards, neatly clipping off most of the central starlight and passing on much of the planetary glow.

天文学家用日冕仪一定程度上解决了观测恒星强光附近物体的难题。日冕仪精巧地阻挡了进入望远镜中央区域的绝大部分恒星光，让更多的行星光进入望远镜。这样一来，日冕仪就能专注于分析望远镜内部圆形黑暗区域周围的入射光。

This composite of both X-ray and Infrared images shows the Coronet Australis region, one of the nearest and most active regions of ongoing star formation.

X-射线和红外图像的合成图，显示的是南冕座，这个"从人马座头上掉落的皇冠"是一个距离我们最近的、生成恒星活动最活跃的星座。

The three stars probed by COROT – known as HD499933, HD181420 and HD181906 – are similar to the sun.

由"科罗特"卫星探测到的三颗恒星分别被称为 HD499933、 HD181420 和 HD181906，跟太阳类似。

The Antennae Galaxies (also known as NGC 4038/NGC 4039) are a pair of galaxies about 68 million ly away in the constellation Corvus.

最近史匹哲太空望远镜的观测显示，在双天线状星系的中心有许多新生的恒星在形成，尤其是在NGC4038和NGC4039交迭的地方。

A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust.

当热恒星的光被宇宙尘埃反射是，产生了显著的蓝色。

Of course, that string is a cosmic trail of gas, dust, and stars about 22,000 light-years long.

当然，连成串的线是一道由气体，尘埃和恒星组成的宇宙潮汐尾，大约有2.2万光年长。

A cosmic bubble of gas and dust, RCW 79 has grown to about 70 light-years in diameter, blown by the winds and radiation from hot young stars.

RCW79，一个由气体和尘埃组成的宇宙气泡，在星风的吹动和炽热年轻恒星的辐射的影响下，它的半径已经扩展到了大约70光年。

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。
