NGC 3199 [2] [1] [3] is an emission nebula in the constellation Carina. It is commonly known as the Banana Nebula [4] or Carina's Smile. [5] The object was discovered in 1826 by the Scottish astronomer James Dunlop. [6]

ngc 3199 [2] [1] [3] 是一個在天球上位於船底座的發射星雲，距離地球約1.2萬光年。 該星雲由英國天文學家 約翰·赫歇爾 發現於1834年4月1日。 NGC 3199是由星雲中心的 沃爾夫–拉葉星 WR 18的恆星風與星際物質交互作用的 弓形震波 所形成 [ 4 ] 。

NGC 3199 (RCW 48) is a bright, 20’ crescent-shaped nebula in the southern constellation of Carina about 12,000 light years distant. Deeper images, as presented above, show the bright crescent to be part of a larger elliptical bubble.

Explanation: NGC 3199 lies about 12,000 light-years away, a glowing cosmic cloud in the southern constellation of Carina. The nebula is about 75 light-years across in this haunting, false-color view. Though the deep image reveals a more or less complete ring shape, it does look very lopsided with a much brighter edge at the lower right.
