The first star to have its parallax successfully measured was in 1838.

人们在1838年第一次成功测量到恒星的视差。

When stars were observed, no parallax was seen.

在观察恒星时，我们看不到视差。

The team used a method known as the " parallax effect" to measure the volcano's plume.

研究小组使用了一被“视差效应”的方法来测量火山的烟柱。

The scientists said they used the parallax effect to examine the images captured from above by satellites.

科学家们说，他们利用视差效应检查了卫星从高空拍摄的图像。

Nor so far wide as to create a parallax distortion.

也不 从而造成脖子酸疼。

We figured this out by measuring how different astronomical objects shift relative to their background–a phenomenon called parallax.

我们通过测量不同的体相对于它们的背景如何移动来弄清楚这一点——一视差的现象。

If we want to measure their distance using parallax, we need a lot bigger baseline than the few centimeters between our eyes.

如果我们想用视差来测量他们的距离，就需要比我们两眼之间的那几厘米更大的基线。

We have to think about how we create depth and parallax using foreground, background elements as the camera moves.

我们必须考虑如何在相机移动时使用前景和背景元素来创建深度和视差。

The parallax effect describes a difference in the apparent position of an object when it is seen along two different lines of sight.

视差效应描述了当物体沿着两条不同的视线观察时，物体的表观位置的不同。

What Gaia is also able to do is to measure those parallaxes down to a level of something like a few hundredths of arcseconds, of milliarcseconds.

盖亚还能够做到的是，将这些视差测量到几百分之一角秒或毫角秒的水平。

We use stereo vision, parallax motion, intuitive physics, and feedback from all our sensory systems to create a mental map of the environment.

我们使用立体视觉、视差运动、直觉物理学和来自我们所有感官系统的反馈来创建环境的心理地图。

So if you know how far away the nearer one is by measuring its parallax, you just have to compare its brightness to one farther away to get its distance.

所以如果你通过测量视差得知离你最近的那颗星有多远，你只需要将它的亮度和离你远的那颗星进行比较，就能得到它的距离。

I play parallax and perspective games with my eyes pretty much all the time, and it's something I've been doing since I was a teenager.

我几乎一直都在用眼睛玩视差和透视游戏，这是我从十几岁起就一直在做的事情。

You can use the principle of parallax to learn how far away a star is or you can look at a star's luminosity to figure out how hot it is.

你可以用视差原理来计算一颗恒星离我们有多远，或者你可以通过观察一颗恒星的亮度来计算它的温度。

They use a distance called the parsec (a contraction of parallax and second), based on a universal measure called the stellar parallax and equivalent to 3.26 light-years.

他们用的距离单位是“秒差距”基于一普遍使用的、名叫恒视差的量度方法，相当于3.26光年。

Scientists hail Gaia's mapping work as crucial to the parallax method, which compares the difference in the direction a star appears to be traveling depending on where on earth it is viewed.

科学家们盖亚的制图工作对视差法至关重要，视差法比较了在地球上的不同位置观察，一颗恒星所显示的行进方向的差异。

To speak of their doings on this pilgrimage, of ingress and egress, of tangent and parallax, of external and internal contact, would avail nothing. Is it not all written in the chronicles of the Astronomical Society?

谈论他们在这次朝圣之旅中的所作所，入口和出口，切线和视差，外部和内部接触，都无济于事。文学的编年史不都是这样写的吗？
