另眼系列之深空
来源:http://gallery.spitzer.caltech.edu/Imagegallery/image.php?image_name=ssc2007-15a1Hubble Ultra Deep FieldIn this image of the Hubble Ultra Deep Field, several objects are identified as the faintest, most compact galaxies ever observed in the distant universe. They are so far away that we see them as they looked less than one billion years after the Big Bang. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy.
The detection required joint observations between Hubble and NASA's Spitzer Space Telescope. Blue light seen by Hubble shows the presence of young stars. The absence of infrared light from Spitzer observations conclusively shows that these are truly young galaxies without an earlier generation of stars.

Hubble and Spitzer Uncover Smallest Galaxy Building BlocksIn this image of the Hubble Ultra Deep Field, several objects are identified as the faintest, most compact galaxies ever observed in the distant universe. They are so far away that we see them as they looked less than one billion years after the Big Bang. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy.
The bottom row of pictures shows several of these clumps (distance expressed in redshift value). Three of the galaxies appear to be slightly disrupted. Rather than being shaped like rounded blobs, they appear stretched into tadpole-like shapes. This is a sign that they may be interacting and merging with neighboring galaxies to form larger structures.

http://ipac.jpl.nasa.gov/media_images/ssc2007-15a.jpg 太浩瀚了！！！::070821_07.jpg:: 嘿嘿 这是一张很常见的照片哦 ::070821_09.jpg:: 图片所示区域在天炉座东北角，如图所示
曝光时间：11.3天（即，1,000,000秒)
曝光日期：September 24, 2003 - January 16, 2004（2003.09.24－2004.01.16）
影像大约占据3平方角秒的天区
该图片与Hubble此前的深空场和南天深空场成一系列,经典的深空照片,图中的星系及其暗淡,一般的拍摄方法根本无法成像,还是哈勃空间望远镜用一百万秒的曝光时间记录了它们

宇宙的浩瀚， 莫过于此！
