The Running Man Nebula (Sh2-279), north of the Orion Nebula, is a blue reflection nebula. Its dust, forming a "running legs" appearance, is slowly being destroyed by embedded stars, expected to dissipate in ~10 million years. Located 1,500 light-years away.

During Artemis I Flight Day 13, Orion reached its max distance (>430,000 km from Earth). From this extreme range, our home world and its Moon appeared nearly the same apparent size to the spacecraft. Artemis II will launch with crew.

M78 is a blue reflection nebula 1,500 light-years away in the Orion Molecular Cloud. Its dust glows by reflecting light from embedded stars. Diffuse hydrogen creates the overall red hue of this star-forming complex, home to the Orion and Horsehead Nebulas.
