NGC 5134
A spiral galaxy, seen tilted diagonally. It has a blue-white, glowing spot at its core. Its oval-shaped disc glows faintly blue throughout with light from its many stars. The disc is filled with waves and strands of bright red dust that swirl around the core. At places there are holes torn in the dust, while elsewhere it forms dense clumps that glow orange. Several tiny, distant galaxies appear across the background.

NGC 5134 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,061±21 km/s, which corresponds to a Hubble distance of 99.2 ± 7.0 Mly (30.40 ± 2.15 Mpc).[1] However, 20 non-redshift measurements give a much closer mean distance of 28.53 ± 3.93 Mly (8.746 ± 1.206 Mpc).[2] It was discovered by German-British astronomer William Herschel on 10 March 1785.[3]

NGC 5134 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]

NGC 5084 Group

NGC 5134 is a member of the NGC 5084 group (also known as LGG 345). This group contains five galaxies, including NGC 5084, NGC 5087, ESO 576-50 (d), ESO 576-40 (d).[6][7]
