The Spiral Galaxy M106 (also known as Messier Object 106, Messier 106, M106, or NGC 4258) is a spiral galaxy in the Canes Venatici constellation. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 21 to 25 million light years away from Earth.
M106 is approximately 25 million light years from the Earth and is located in the constellation Canes Venatici and very close to the better known constellation of Ursa Major.
M106 is intermediate between a "barred" spiral and a "normal" spiralgalaxy which gives it a very eye-catching appearance.
It is a very active galaxy and shines extremely bright in the radio as well as the high energy portion of the spectrum and is thus classified a "Seyfert" galaxy.
