Are lasers from giant telescopes being used to defend the Earth? No. Lasers shot from telescopes are now commonly used to help increase the accuracy of astronomical observations. In some directions, Earth atmosphere-induced fluctuations in starlight can indicate how the air mass over a telescope is changing, but in other directions, no bright star exists. In these directions, astronomers can create an artificial star with a laser. Subsequent observations of the artificial laser guide star can reveal information so detailed about the changing blurring effects of the Earth's atmosphere that much of it can be removed by rapidly flexing a telescope's mirror. Such adaptive optics techniques allow high-resolution ground-based observations of real stars, planets, and nebulas. Pictured here, telescopes at Paranal Observatory in Chile study a colorful sky filled with green airglow and the Magellanic Clouds on the left, red airglow on the right, and the majestic central band of our Milky Way Galaxy arching across the center.

你好,幸会了!

生存问题虽然没有解决,但是决定全身心开始工作

大奖,一直没有。

收入一直没有。但是,我知道,时间越少越少,

危机越来越多。

我必须开始全身心投入工作了。

必须完成我的使命和责任。

首先需要构思大概内容。书写出来。

在新网站上。

然后,每天写一些思想,充实内容。

数学逻辑学物理学,很多地方不明确,

但是,没法细致研究了,必须完成我的工作。

那就把想法写出来吧。

提纲,细节。未来伏笔。过去埋笔。

都要用文字体现出来。开始吧。阿们。
