Scanning the skies for galaxies, Canadian astronomer Paul Hickson and colleagues identified some 100 compact groups of galaxies, now appropriately called Hickson Compact Groups. The four prominent galaxies seen in this intriguing telescopic skyscape are one such group, Hickson 44. The Hickson 44 galaxy group is about 100 million light-years distant, far beyond the foreground Milky Way stars, toward the northern springtime constellation Leo. The two spiral galaxies in the center of the image are edge-on NGC 3190 with distinctive, warped dust lanes, and S-shaped NGC 3187. Along with the bright elliptical, NGC 3193 (left) they are also known as Arp 316. The spiral toward the lower right corner is NGC 3185, the 4th member of the Hickson group. Like other galaxies in Hickson groups, these show signs of distortion and enhanced star formation, evidence of a gravitational tug of war that will eventually result in galaxy mergers on a cosmic timescale. The merger process is now understood to be a normal part of the evolution of galaxies, including our own Milky Way. For scale, NGC 3190 is about 75,000 light-years across at the estimated distance of Hickson 44.

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。
