CG 4 :球體與銀河系
CG4: The Globule and the Galaxy

發表日期:2024-05-21
氣體雲能吞噬星系嗎? 還差得遠呢。 照片中這個長相奇特的 "生物 "的 "爪子 "是被稱為彗星球的氣體雲。 不過,這個球體已經破裂了。 彗星球的典型特徵是頭部多塵,尾部拉長。 這些特徵使彗星球在視覺上與彗星非常相似,但實際上它們有很大的不同。 球粒經常是恆星的誕生地,許多球粒的頭部都有非常年輕的恆星。這個天體頭部破裂的原因尚不清楚。球體左側的星系非常巨大,距離很遠,只是由於偶然的疊加才被放置在CG 4 附近。
原文:Can a gas cloud eat a galaxy? It's not even close. The "claw" of this odd looking "creature" in the featured photo is a gas cloud known as a cometary globule. This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails. These features cause cometary globules to have visual similarities to comets, but in reality they are very much different. Globules are frequently the birthplaces of stars, and many show very young stars in their heads. The reason for the rupture in the head of this object is not yet known. The galaxy to the left of the globule is huge, very far in the distance, and only placed near CG4 by chance superposition.
