Cometary blood cell CG4 in the stern - CG4, a cometary blood cell in Puppis - Cometary blood cells are small clouds of isolated gases. The latter, called CG4, is located about 1300 light years ago in the constellation of Pupus. Its head is 1.5 years light and its tail extends for 8 years. This cloud is a star-forming region. A spiral galaxy seen by the slice (ESO 257 - 19) is visible at the top left. It is located 100 million years later. The odd looking “” creature”” to the right of center in the above photo is a gas cloud known as a cometary globule.This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails. These features cause cometary globules to have visual similarities to comets, but in reality they are very much different. Cometary globules are frequently the birthplaces of stars, and many show very young stars in their heads. The reason for the rupture in the head of this object is not completely known. The galaxy to the left of center is very far in the distance and is only placed near CG4 by chance superposition
