M78, Reflection Nebula in Orion |
This busy area is located in the
constellation Orion, with reflection nebula Messier 78 at the
center. M78 is about 1,600 light-years away and not too far
(from our perspective) from the famous Horsehead Nebula.
Reflection nebulae such as M78 are dust
clouds that reflect the light from bright stars in their
vicinity. Reflection nebulae are blue in color for the same
reason that the Earth’s daytime sky is blue: the dust
preferentially scatters blue light in a manner similar to the
Earth’s atmosphere. This region is also the site of a recent amateur discovery. In February 2004, Jay McNeil of Paducah, Kentucky, was trying out a new telescope and CCD camera, and aimed this at M78 for a test shot. Being an astute observer, he spotted something in his image was not in other photos of the area. The object, which is a variable nebula, has been dubbed McNeil’s Nebula. |
