But with the advent of radio astronomy we figured that out too.

但随着射电天文学的出现，我们也能弄明白了。

Yet the physics of radio astronomy means that such mighty machines are, nevertheless, fairly crude.

然而从射电天文学涉及的物理现象来说，这些巨大的设置显得十分“粗笨”。

This is like the discovery of radio astronomy or this is like starting radio astronomy after only being able to observe the universe in visible light.

这就像对射电天文学的发现——或者说在只能用可见光观测宇宙之后，我们开启了射电天文学。

There is a technique. It's called radio astronomy.

有一个技巧。这叫做射电天文学。

You essentially have two options to get high-quality radio astronomy data: more time or more space.

本质上，您有两种选择来获取高质量的射电天文学数据：更多时间或更多空间。

And fortunately, the entire field of radio astronomy is built on the fact that there are bright radio signals in the sky.

幸运的是，整个射电天文学领域都建立在天空中存在明亮射电信号这一事实之上。

Professor : Well, the thing is, with the radio astronomy, you can’t just set up a telescope in you backyard and observe stars.

教授：嗯，问题是，对于射电天文学， 你不能只是在自家后院架起望远镜来观察星星。

The sixth will assess the Moon's potential as a site for radio astronomy, as well as the challenges of radio communication from a location where Earth is always low on the lunar horizon.

第六个将评估月球作为射电天文学站点的潜力，以及从地球始终处于月球地平线低处的位置进行无线电通信的挑战。

The researchers will further focus on nanohertz gravitational waves and open up a new scientific direction of nanohertz gravitational wave astronomy, and continue to maintain the country's leading position in low-frequency radio astronomy in the world, said Chang.

研究人员将进一步聚焦纳赫兹引力波， 开辟纳赫兹引力波天文学新的科学方向，继续保持我国在低频射电天文学领域的国际领先地位。

The other is very close by, a radio astronomy observatory located in the suburbs of Beijing, which is run by the Chinese Academy of Sciences and Peking University's Joint Center for Astrophysics.

另一个离得很近，是位于北京郊区的射电天文台，由中国科学院和北京大学天体物理联合中心运营。

But constructing this image was a feat of radio astronomy and was achieved by  combining the signals from 8 radio telescopes all around the world to create a virtual telescope  the size of the Earth; an amazing achievement.

但是构建这张图像是射电天文学的一项壮举， 它是通过结合来自世界各地 8 台射电望远镜的信号来创建一个地球大小的虚拟望远镜来实现的;这是一项了不起的成就。
