M78 - Reflection Nebula

M78 is a reflection nebula located in the constellation Orion. It was discovered by Pierre Méchain in 1780 and later cataloged by Charles Messier. M78 is part of the Orion Molecular Cloud Complex and is one of the brightest reflection nebulae in the sky.

M78 spans about 5 light-years across and contains several young stars that illuminate the surrounding dust. The nebula is approximately 1,600 light-years away from Earth and has an apparent magnitude of 8.3, making it visible with binoculars or a small telescope.

M78 — Image Gallery

DSS Blue

M78 — blue-filter image
Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

M78 — red-filter image
Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

M78 — near-infrared image
Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

M78 — composite color image
DSS color images combine blue, red and often near-infrared exposures into a composite view.

The images come from the Digitized Sky Survey 2 (DSS2), produced at the Space Telescope Science Institute (STScI) under contract with NASA, using data from UK Science and Technology Facilities Council (STFC), European Southern Observatory (ESO), National Geographic Society-Palomar Observatory Sky Survey (POSS II).

Special thanks to National Optical Astronomy Observatory (NOAO), Royal Observatory, Edinburgh, California Institute of Technology for their significant contributions.
