'''NGC 1165''' is a barred spiral galaxy located in the constellation ]. It lies approximately 61 million light-years away from ] and was discovered by astronomer ] in 1834. |
|
|
|
|
|
== Structure and Characteristics == |
|
|
NGC 1165 is classified as an SB(rs)b type galaxy, indicating that it is a barred spiral galaxy with a prominent central bar and slightly loose spiral arms. The galaxy spans approximately 1.8 × 1.4 arcminutes in the sky and features active star-forming regions within its spiral arms. |
|
|
|
|
|
Observations using infrared and optical telescopes suggest the presence of a central supermassive black hole, a common feature in many barred spiral galaxies. The galaxy also exhibits regions of intense star formation, indicated by high concentrations of ionized hydrogen gas. |
|
|
|
|
|
== Discovery == |
|
|
NGC 1165 was discovered by the British astronomer ] during his observations of the southern skies in 1834. Since its discovery, it has been a subject of interest for astronomers studying barred spiral galaxies and galactic evolution. |
|
|
|
|
|
== Location and Distance == |
|
|
NGC 1165 is situated in the constellation ] and is approximately 61 million light-years away from the ]. Its radial velocity has been measured at around 3954 km/s, indicating its movement relative to our galaxy. |
|
|
|
|
|
== Significance == |
|
|
Barred spiral galaxies like NGC 1165 provide valuable insight into galactic dynamics and evolution. The study of such galaxies helps astronomers understand the role of bars in driving star formation and the distribution of interstellar matter. |
