- Messier 77 (M77), also known as NGC 1068 or the Squid Galaxy, is a barred spiral galaxy in the constellation Cetus. It is about 47 million light-years (14 Mpc) away from Earth, and was discovered by Pierre Méchain in 1780, who originally described it as a nebula.

Discovery. NGC 1068 (Messier 77), one of the first Seyfert galaxies classified. Seyfert galaxies were first detected in 1908 by Edward A. Fath and Vesto Slipher, who were using the Lick Observatory to look at the spectra of astronomical objects that were thought to be "spiral nebulae".

May 30, 2024 · We present a comprehensive multi-messenger study of NGC 1068, the prototype Seyfert II galaxy recently associated with high-energy IceCube neutrinos. Various aspects of the source, including its nuclear activity, jet, outflow, and starburst region, are analyzed in detail using a multi-wavelength approach and relevant luminosities are derived.

- Locating Messier 77
Located about 60 million light years away from our solar system and speeding away from us at 1100 kilometers per second, this grand galaxy could cover as much expanse as 170,000 light years at its extremities. That’s almost double the size of the Milky Way! Its broad spiral arms hold more evolved yellow stars like our own Sun, but towards the core ...
I wonder if Pierre Mechain even had a clue on October 29, 1780 when he first saw this incredible spiral galaxy if there were such a science going on behind it. Messier looked at it, but did not record it. In this circumstance, Mechain did: “Cluster of small stars, which contains some nebulosity, in Cetusand on the parallel of the star Delta, report...
M77 can be easily found less than a degree east/southeast from the 4th magnitude Delta Ceti. This magnificent face-on spiral galaxy can be spotted with smaller binoculars from a dark sky location as a round contrast change and is easily seen in small telescopes. As aperture increases, so does detail and high magnification works well with this galax...

1.1 Seyfert Galaxies. The first optical spectrum of an active galaxy was obtained at Lick Observatory by E.A. Fath in 1908 as part of his dissertation work. He noted the presence of strong emission lines in the nebula NGC 1068.
