Long-exposure night-time photograph of DU's historic Chamberlin Observatory. The brick building is lit in a warm glow of downward-facing light fixtures and surrounded by lush green pine trees. The stars in the sky above the building are moving, forming an implied circle around the North Star, Polaris.

Image of galaxy M77.

M77 is one of the largest galaxies in the Messier catalog. It is located in the constellation Cetus at a distance of 45 million light-years from Earth. M77 has an apparent magnitude of 9.6 and is visible in a small telescope. It is most easily observed during December.

Initially identified as a nebula by the French astronomer Pierre MΓ©chain in 1780. Both Messier and MΓ©chain were comet hunters who cataloged nebulous objects that could be mistaken for comets. Messier, MΓ©chain, and other astronomers of their time mistook the M77 for either a spiral nebula or a star cluster. This mischaracterization isn’t surprising. More than a century would pass between the discovery of M77 and the realization that the β€˜spiral nebulae’ scattered across the sky were not part of our galaxy but were in fact separate galaxies millions of light-years away.
