Messier 77 is an w:active galaxy with an w:Active Galactic Nucleus (AGN), which is obscured from view by astronomical dust at visible wavelengths. The diameter of the molecular disk and hot plasma associated with the obscuring material was first measured at radio wavelengths by the w:VLBA and w:VLA. The hot dust around the nucleus was subsequently measured in the mid-infrared by the MIDI instrument at the w:VLTI. It is the brightest http://adsabs.harvard.edu/abs/1973ApJ...181...31D Southern Galaxies.VI.

History Messier 77 was discovered by w:Pierre Méchain in w:1780, who originally described it as a nebula. Méchain then communicated his discovery to w:Charles Messier, who subsequently listed the object in his catalog.K. G. Jones 1991 Messier's Nebulae and Star Clusters 2nd Cambridge University Press Cambridge 0-521-37079-5 Both Messier and w:William Herschel described this galaxy as a star cluster. Today, however, the object is known to be a galaxy.
