Target: Lobster Nebula
Located about ~5,500 light years away from Earth, the Lobster Nebula NGC 6357 is a diffuse nebula containing many proto-stars shielded by dark discs of gas, and small young stars wrapped in expanding "cocoons" of gas.*
This nebula was also given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its resemblance to a dove and a skull in infrared, although all I see is a cosmic koala at the helm of a spaceship.
