**B2 1441+26** is a [radio galaxy](/source/Radio_galaxy) located in the constellation of [Boötes](/source/Bo%C3%B6tes). The redshift of the galaxy is (z) 0.061[1] and it was first discovered by [astronomers](/source/Astronomer) in October 1983 from the B2 catalogue and such contains a double radio source.[2]

## Description

B2 1441+26 is categorized as a [Fanaroff-Riley](/source/Fanaroff%E2%80%93Riley_classification) Class Type 1 low [luminosity](/source/Luminosity) radio galaxy.[3][4][5] It is found to be hosted by a nearly face-on [spiral galaxy](/source/Spiral_galaxy) although some studies suggest the host may might be an [elliptical galaxy](/source/Elliptical_galaxy) instead.[6][7][8] Studies also classify this as a weak radio galaxy (WRG) based on [optical](/source/Optics) images with an ordinary [galactic disk](/source/Galactic_disc). There also a presence of an inner structure or a [spiral](/source/Spiral) patterned bar feature. Two companions have been found located both east and northeast from the galaxy's nucleus.[6] The [extended emission-line region](/source/Extended_emission-line_region) of the galaxy is shown unresolved.[9]

The source of the galaxy has been found as double,[2] being resolved into two separate components with further evidence that they contain a steep [radio spectrum](/source/Radio_spectrum) in addition.[10] There are presence of two asymmetric [radio lobes](/source/Radio_galaxy), with the lobe on the eastern side being as twice more luminous and being more [polarized](/source/Polarized) three times more compared to the lobe on the western side.[11][12] The lobes also have a different [magnetic field](/source/Magnetic_field) direction, being [orientated](/source/Orientation_(geometry)) parallel towards the axis of the source but also in an almost perpendicular direction.[11] Towards the inner region of the lobes, there is a steepening of the spectrum although the low brightness meant the tracing of steepening along the lobes' length is only halfway.[13] A radio core is found embedded inside the eastern lobe.[7]
