在宇宙的深處，有一個名叫Cigar Galaxy的星系，也就是M82。這個星系最近因為靠近一個大的螺旋星系M81而變得熱鬧起來。可是，這並不能完全解釋為什麼出現了發紅的氣體和塵埃。科學家發現，這些氣體和塵埃是因為很多星星發出的粒子風一起把它們推了出去，形成了一種叫做「銀河超風」的現象。這些塵埃粒子像香煙的煙霧一樣，是從Cigar Galaxy的星際空間中來的。這幅照片是由哈勃太空望遠鏡和詹姆斯韋伯太空望遠鏡拍的，結合了可見光和紅外光的影像。圖片的中間是這顆星系的亮白色部分，上面和下面都伸展著驚人的橙色和紅色氣體和塵埃，這些氣體和塵埃的長度超過了10,000光年。Cigar Galaxy距離我們有1200萬光年，是天空中最亮的紅外光星系，還可以用小望遠鏡在大熊座（Ursa Major）那個方向看到它。
原文:
Why is the Cigar Galaxy billowing red smoke? M82, as this starburst galaxy is also known, was stirred up by a recent pass near large spiral galaxy M81. This doesn’t fully explain the source of the red-glowing outwardly expanding gas and dust, however. Evidence indicates that this gas and dust is being driven out by the combined emerging particle winds of many stars, together creating a galactic superwind. The dust particles are thought to originate in M82’s interstellar medium and are actually similar in size to particles in cigar smoke. The featured photographic mosaic combines images taken in visible light from the Hubble Space Telescope and images taken in infrared light from James Webb Space Telescope. It shows the light-colored central galaxy nearly edge on across the image center with tremendous orange and red colored filaments of gas and dust extending both up and down. The filaments extend for over 10,000 light years. The 12-million light-year distant Cigar Galaxy is the brightest galaxy in the sky in infrared light and can be seen in visible light with a small telescope towards the constellation of the Great Bear (Ursa Major).
