Explanation: A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker: the Seagull Nebula. This portrait of the cosmic bird covers a 1.6-degree wide swath across the plane of the Milky Way, near the direction of Sirius, the alpha star of the constellation of the Big Dog (Canis Major). Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission and reflection nebula with an embedded massive star that forms the bird’s head. Dominated by the reddish glow of atomic hydrogen, the complex of gas and dust clouds with bright young stars spans over 100 light-years at an estimated 3,800 light-year distance.

说明: 这大片发光气体与尘埃云，对地球上的天文学家来说形如鸟面，故有海鸥星云之昵称。这幅呈现宇宙之鸟的影像，涵盖了大犬座最亮星天狼方向、分跨在银河系盘面二侧的1.6度天区。此区域当然还有带着其他编录号的天体，其中最醒目的为NGC 2327，而这团紧凑、内藏大质量恒星的尘埃发射与反射星云，则是海鸥的头部。以原子氢的泛红辉光为主色的这个气体、尘埃云和年轻亮星复合体，如果用3,800光年的估计距离来换算，其跨幅超过100光年。
