spiral galaxy

基本解釋

This band is the disk of our spiral galaxy.
這條光帶就是我們這個(gè)漩渦星系的銀盤。
Can you find, in the above image, a comet, a spiral galaxy, an open star cluster, and a supernova remnant?
在上面圖中，你能找到：一彗星，一旋渦星系，一疏散星團(tuán)和一超新星遺跡嗎？
It is the fate of the spiral galaxy to be pulled like taffy and then swallowed by the pair of elliptical galaxies, which will trigger a firestorm of new stellar creation.
這個(gè)漩渦星系將不可避免的被像太妃糖一樣拉長(zhǎng)，最后被那一對(duì)橢圓星系吞掉，而這將觸發(fā)一場(chǎng)恒星誕生烈火風(fēng)暴。

Mr. Reid noted that: "Our galaxy probably has 4, not 2, spiral arms of gas and dust that are forming stars."
Recent observations had suggested that 2 of the 4 spiral arms hold most of the older stars in the Milky Way galaxy.
The new information also adds to astronomers' understanding of our galaxy's spiral arms.

We even get to see a (relative) close-up of a "barred spiral galaxy" (above) called NGC 1365.

a galaxy consisting of an ellipsoidal nucleus of old stars from opposite sides of which arms, containing younger stars, spiral outwards around the nucleus. In a barred spiral the arms originate at the ends of a bar-shaped nucleus
