The blue reflection nebula M78 lies about 1,600 light-years away in Orion. It is a cloud of interstellar gas and dust that owes its luminosity to embedded, bright, blue, early B-type stars — making it the brightest diffuse reflection nebula in the Orion B molecular cloud complex.

This 1874 lithograph was created by Étienne Léopold Trouvelot with the 15-inch refractor at the Harvard College Observatory, for the purpose of measuring the nebula’s extent. A glass plate with dark black lines was placed on the focus of the telescope for marking placement. No wonder it shows no central star.
