埃特纳火山是地球上著名的平流层活火山，它的山顶发出的光芒，在这幅山脉和夜空的地平线上脱颖而出。来自银河系无数恒星群的漫射光带横跨天空。在侧影中，银河系巨大的尘埃云沿着银道平面聚集在一起。对于北方的天文爱好者来说，同样熟悉的还有明亮的恒星：天津四、织女星和牛郎星，横跨黑暗星云的夏季三角和在火山山顶上保持平衡的明亮恒星云。深组合曝光揭示了沿银河系活跃的恒星形成区域的光，呼应了北半球夏夜埃特纳火山的红色色调。

A glow from the summit of Mount Etna, famous active stratovolcano of planet Earth, stands out along the horizon in this mountain and night skyscape. Bands of diffuse light from congeries of innumerable stars along the Milky Way galaxy stretch across the sky above. In silhouette, the Milky Way's massive dust clouds are clumped along the galactic plane. Also familiar to northern skygazers are bright stars Deneb, Vega, and Altair, the Summer Triangle straddling dark nebulae and luminous star clouds poised over the volcanic peak. The deep combined exposures reveal the light of active star forming regions along the Milky Way, echoing Etna's ruddy hue in the northern hemisphere summer's night.
