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.

研究小组使用了一种被称为“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.

也不会太斜 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天体相对于它们的背景如何移动来弄清楚这一点——一种称为视差的现象。

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。
