在遙遠的宇宙中，有一個名叫NGC 7497的美麗螺旋星系，距離我們約60萬光年遠。當我們仰望星空，看到的每顆明亮的星星都是我們銀河系中的一部分，這些星星周圍的光輝還是由星際塵埃所形成的雲朵。這些雲朵叫做galactic cirrus，它們在銀河的平面上漂浮，散發著柔和的光亮。你知道嗎？其實在這片星空上，還有一塊被塵埃包圍的地方，這就是很靠近我們的MBM 54雲。它就在千光年以內！如果我們細心觀察，就會發現這片星際塵埃的影像與我們銀河系中的星星和塵埃相互交織，就像在宇宙中尋找最美的拼圖。在這片魔幻的星空中，我們可以看到這些閃亮的星星與藍色的星雲交錯，引導我們探索宇宙的奧秘。

This well-composed telescopic field of view covers over a Full Moon on the sky toward the high-flying constellation Pegasus. Of course the brighter stars show diffraction spikes, the commonly seen effect of internal supports in reflecting telescopes, and lie well within our own Milky Way galaxy. The faint but pervasive clouds of interstellar dust ride above the galactic plane and dimly reflect the Milky Way’s starlight. Known as galactic cirrus or integrated flux nebulae they are associated with the Milky Way’s molecular clouds. In fact, the diffuse cloud cataloged as MBM 54, less than a thousand light-years distant, fills the scene. The galaxy seemingly tangled in the dusty cloud is the striking spiral galaxy NGC 7497. It’s some 60 million light-years away, though. Seen almost edge-on near the center of the field, NGC 7497’s own spiral arms and dust lanes echo the colors of stars and dust in our own Milky Way.
