galactic gas and dust
解釋
銀河氣塵-
In this graph, the galactic plane is horizontal and we ignore the distances. note that the gas and dust in our galaxy not only block the stars in our galaxy, but also the galaxies far away. taking this into consideration, the distribution of the galaxies is fairly uniform
圖中中間的水平線標示出銀河系平面,銀河系的氣體塵埃除了掩蓋了背景星光,亦同時遮蔽了遙遠的星系,撇除了這個因素,我們會發覺星系在天空的分佈是頗為平均的。
