![]() They are overlaid on a view of the region in visible light. This star-forming region is located about 1,350 light-years away. map of the reflection nebula NGC 2068 (Messier 78) is presented. The submillimetre-wavelength observations, made with the Atacama Pathfinder Experiment (APEX) telescope and shown here in orange, use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. Messier 78, or M78, is one of the brightest reflection nebulas in the sky and can be easily observed with a small telescope. 131.195 An investigation of the interstellar I. blue hue of reflection nebulae is caused by the tendency of interstellar dust. This image of the region surrounding the reflection nebula Messier 78, just to the north of Orion’s belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. Messier 78 (also known as NGC 2068) is a reflection nebula that spans some. ![]() ![]() It is illuminated over an expanse of four light years by the by the energy of its embedded, bright blue, early. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionize the gas to make it glow its dust particles simply reflect the starlight that falls on them. M78 is a cloud of interstellar dust located about 1,600 light years from Earth.
