From
Wikipedia:
Messier 77 (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 and
VLA. The hot dust around the nucleus was subsequently measured in the mid-infrared by the
MIDI instrument at the
VLTI. It is the brightest
Seyfert galaxy and is of type 2.
Messier 77's diameter is 170,000 light-years.
