M78 - Reflection nebula in Orion


Copyright 2007 Frank Hinson

Classified as a reflection nebula, M78 is a cloud of interstellar gas and dust glowing by reflected starlight.  It has the bluish color characteristic of all reflection nebulae.  M78 is actually composed of several smaller objects...the bright NGC2067 near the bottom and the fainter NGC2071 near the top.  If you look closely, you can make out vast regions of light obscuring dust crossing in front of each portion.  A much longer total exposure is required to really tease out the detail in these dust lanes...a project for later this winter.  The M78 complex is approximately 4 light-years across and is part of the much larger region of gas and dust surrounding and penetrating the constellation of Orion.

M78 lies at a distance of 1600 light years.
