(also known as NGC 1068
) is a barred spiral galaxy
about 47 million light-years
away in the constellation Cetus
. Messier 77 is an active galaxy
with an 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 VLBA
. The hot dust around the nucleus was subsequently measured in the mid-infrared by the MIDI
instrument at the VLT
I. It is the brightest Seyfert galaxy
and is of type 2.
Messier 77's diameter is 170,000 light-years.
