1. One is the general atmosphere of secrecy in which it is carried out,
    一是科研工作中普遍存在的保密气氛；

2. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets.
    地球周围温暖的大气层和望远镜散出的热量使得我们根本不可能找到比行星更小的物体。

3. Of course, the Hubble is above the earth´s atmosphere, so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen.
    当然，哈勃位于地球的大气层之外，因此，它很快就会给我们传送我们所见到过的、有关行星和远距离星系的最清晰的照片。

4. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions.
    然后给它以充足的食物和水，一定不要惊扰它，以便让他能适应新居的气氛，并且看到自己的同伴身上没有发生让自己担惊受怕的事。
