橢圓星系 NGC 1132

說明: NGC 1132 是一個平滑的星系，但它是如何形成的？NGC 1132 是一個橢圓星系，因此少有塵埃和氣體，最近也很少有新恆星形成。雖然有許多橢圓星系是存在於星系團之中，但位於波江座的 NGC 1132 似乎是一個巨大的孤立星系。為了研究這個擁有數百萬兆顆恆星的星系的過去，天文學家們利用可見光波段的哈伯太空望遠鏡以及X光波段的錢卓拉太空望遠鏡對 NGC 1132 進行觀測。在這張合成的假色影像中，可見光是以白色表示，而X光則是以藍色表示，而它所代表的意義便是異常高溫的氣體。X光波段也能描繪出暗物質的位置。有一個假設認為 NGC 1132 是由一個小星系群進行一系列星系融合之後的產物。NGC 1132 的距離大約是三億光年遠，因此我們現在看到的光是在恐龍時代之前就發出來的。在更遙遠的地方，可以看到許多迷人的背景星系。



Elliptical Galaxy NGC 1132

Explanation: NGC 1132 is a smooth galaxy, but is it to how become?NGC 1132 is an Elliptical galaxy, the friendly body of the therefore rare dust, recently also the few new fixed star become.Although have many Elliptical galaxies is exist in cluster of galaxies, be located a NGC of river's 1132 apparently BE a huge isolated galaxy.For studying this galaxy that owns the millions trillion a fixed star of past, the astronomerses make use of it is thus clear that the space telescope of 哈伯 of the light wave segment and QIAN2 ZHUO2 LA's space telescope of the X light wave segment to NGC 1132 carry on prognosticate.In this false color image that synthesize, it is thus clear that only indicate with the white, and the X light then indicates with the blue, and the meaning that it represent woulds be the air of the excrescent heat.The X light wave segment also can describe the dark material position.There is an assumption think NGC 1132 by an outcome that small galaxies carry on after a series of galaxy blend.NGC 1132 of the distance is about 300,000,000 light years far, so we see only now to send out to come times before the dinosaur.At the more faraway place, can see many charming background galaxies.
