Comments: This region of the southern sky has numerous colorful faint gaseous nebulae that are very difficult to image due to thier very low surface brightness. CG4 is a ruptured cometary globule that appears to be ready to "eat" the distant galaxy ESO257-019. In fact, these two objects are very far apart; ESO257-019 being more than 100 million light years further away than CG4. Cometary globules are isolated, relatively small clouds of gas and dust within the Milky Way. CG4, is about 1,300 light years from Earth. Its head is some 1.5 light-years in diameter, and its tail is about eight light-years long. The dusty cloud contains enough material to make several Sun-sized stars. A closer view of CG4 may be seen here. Other cometary globules in the region are CG1 and 2.
