NGC 1166 is a barred spiral galaxy located in the constellation Eridanus. It is situated approximately 53 million light-years away from Earth and was discovered by the British astronomer John Herschel on November 17, 1834.^[2]

Structure and characteristics

NGC 1166 is classified as an Sb-type barred spiral galaxy. This means the galaxy has a well-defined bar at its center, with spiral arms extending outward. It is a relatively medium-sized galaxy, spanning approximately 2.0 x 1.8 arcminutes in the sky. The galaxy exhibits active star formation in its spiral arms, where new stars are being created from interstellar gas and dust.

NGC 1166 also has a high surface brightness, making it an interesting target for both optical and infrared studies.^{[ citation needed ]}

Discovery

NGC 1166 was discovered by the renowned astronomer John Herschel during his survey of the southern skies in 1834. Herschel's extensive cataloging of nebulae and galaxies led to the inclusion of NGC 1166 in the New General Catalogue (NGC), where it is listed among other deep-sky objects.^{[ citation needed ]}

Location and distance

NGC 1166 is located in the constellation Eridanus, a large and prominent southern constellation. The galaxy is about 53 million light-years away from Earth, with a radial velocity of approximately 3530 km/s, indicating its motion relative to the Milky Way.^{[ citation needed ]}

Importance and research

NGC 1166 is a useful object of study for astronomers researching the formation and evolution of barred spiral galaxies. Its relatively close proximity allows for detailed observation, and its active star-forming regions provide insights into the processes that drive galaxy evolution.^{[ citation needed ]}
