NGC1977 is often referred to as
the "Running Man Nebula" because, with some imagination,
the dark lanes look like a ... running man.
It lies a mere 1,500 light years
away. It lies just north of M42 (the Great Orion Nebula) in the
sword of Orion. In contrast with M42, it does not emit its own light.
It appears blue because it reflects the light of nearby stars.
