周坚每日解读一天文图
应用《解析宇宙学》探索宇宙! 每天发布一张基于中国科学家周坚于2009年3月8日创立的《解析宇宙学》（著作权登记号是2009-A-020687）理论解读反映我们迷人宇宙的不同影像或照片，重点给出影像或照片中天体的解析宇宙学参数以及相关比较结果。

庆祝哈勃升空18周年美公开59张星系相撞奇观照的第24幅ESO286-19相撞星系
ABOUT THIS IMAGE:
ESO 286-19 is a peculiar galaxy that consists of what were originally two disk galaxies that are now in the midst of an ongoing collision. It has undergone a burst of star formation that ended about eight million years ago. ESO 286-19 has a long tail to the right of the main body, and a shorter tail curving to the left. The presence of the tails is a unique signature of the merger process: gas and stars were stripped out by rippling gravitational pulls as the galaxies collided and the outer regions of the parent galaxies were torn off. These tidal tails can persist long after the galaxies have finally merged. ESO 286-19 is located 600 million light-years away from Earth and is an exceptionally luminous source of infrared radiation.
This image is part of a large collection of 59 images of merging galaxies taken by the Hubble Space Telescope and released on the occasion of its 18th anniversary on 24th April 2008

周坚于2010年8月20日公布的ESO286-19相撞星系解析宇宙学参数
从影像中观察，这个ESO286-19星系很特别，其右边有一条长长的尾巴，而长尾巴的末端还向左端弯曲，构成星系相撞过程的一种独特标志，真不愧是星系相撞的宇宙壮丽景观呀！据资料显示，ESO286-19位于显微镜座，距离大约是6亿光年。据解析宇宙学参数显示，ESO286-19的标准距离是5.677300亿光年（174.063522Mpc），而诸多其它参数以及比较情况敬请参阅上述参数表，而表中的数据来自解析宇宙学所涉及的计算公式已经上传到本人的三个主要博客中了（强国博客http://blog.people.com.cn/blog/c48/s294173,w1282050005205226；
