The sphere, for instance, represents how space is bent around a star or other mass - light passing through this warped space bends in an effect called gravitational lensing.
作为例子,这个球面代表了恒星或其他质量附近的空间是怎样弯曲的-光通过这个扭曲空间所引起的弯曲称为引力透镜效应。
That means they should escape the star almost immediately, while photons of light will take about 3 hours.

If a large object passes in front of a more distant background star, it may act as a lens, bending and distorting the light of that star so that it may appear to brighten significantly.
如果一个体积足够大的星体从一个距离很远的恒星前面经过,那么会产生透镜效果,使那个恒星的光线产生弯曲或变形,这样就能很清楚的看到这个星体。
Instead, Dr Marcy and others like him look for changes that the wobbles cause in the wavelength of the light from the star.
相反,马西博士与像他那样的其他科研人员在尽力发现一些变化,即恒星发出光束的波长受位置移动的影响而造成的变化。
Because a planet that close to its star would dim the dwarf's light as it passes.
因为,当一颗靠近白矮星的行星路过它的时候,会使它发出的光线变的模糊不清。
Other artists have created tangible works such as a Star Wars Steampunk light saber made from old radio parts and evening a functioning R2D2 Steampunk robot.
其他艺术家们还制作了一些实体装置,第二张图里展示的是一把用旧收音机零件制成的光剑,第三张图里是一台真的可以活动的机器人R2D2。
Here, the bright star near the dust vortex creates the light of surrounding reflection nebula.
在这里,尘埃涡流附近的亮恒星使附近的反射星云呈蓝色。
That instrument, an even more expensive space telescope, will require some means of blocking the light from a star in order to detect light reflected by its planet.
作为一个价值千金的天文望远镜,这个仪器需要一些能够掩盖星光的方法,从而使其更好的探测行星的反射光。
This means that light from a star that Kepler is examining is sometimes "polluted" by light from other stars that appear near to it in the sky.
原因是有时开普勒观察到的来自恒星的光会被其它邻近恒星所发出的光给误导。
Instead the failed star ultimately cools and emits most of its light at infrared wavelengths.
因此这颗不成熟的恒星最终将会冷却并在红外波段发射出其大部分的光芒。
By 2024, say the team, our planet's computers will be getting through enough data every year to build a stack of books as far as the next star, Alpha Centauri, 4.37 light years away.
据这个小组说,到了2024年,我们星球的计算机每年消耗的数据量将可以建造一堆足以到达下一颗星球- 4.37光年之外的半人马座阿尔法星-的书了。
The planet is one of three extrasolar planets orbiting the young star HR 8799, which lies 130 light-years away.

It orbits a red dwarf star about 28, 000 light-years away, making it the most distant exoplanet currently known.
它围绕着一颗距地球28,000光年远的红矮星运行,这使它成为目前已知的最远的外行星。
This was quite a feat as the intense light from the star normally obscures the subtle visual details necessary to distinguish a planet.
这可以算得上是个相当壮举,因为恒星发出得强烈光芒掩盖了区分行星所需得视觉细节。
Last month, astronomers announced the discovery of the most Earth-like planet ever found - a rocky world three times the size of our own world, orbiting a star 20 light years away.
上月,天文学家宣称已发现最类似地球卫星——其大小为地球的三倍,表面为岩石覆盖,距离其环绕的恒星20光年。
