IC 1318 – Butterfly Nebula


Sadr, the central star of the Northern Cross, is surrounded by extensive regions of emission nebulosity. One such region is IC 1318, also known as the Bufferfly Nebula. The dark lane separating the two “wings” is a dark nebula known as LDN 889. Sadr shines at magnitude 2.2, and is about 1550 light-years from Earth. The name is Arabic for “The Hen’s Chest”.
