From this vantage point, UGC 10043's disk appears as a distinct line with thick, dark dust lanes that obscure the light of the stars. If viewed from above, these dust formations would likely highlight the galaxy's spiral arms. Despite the obscuring effect of the dust, bright star-forming regions shine through, adding intricate detail to the image.
At the galaxy's center lies a luminous, egg-shaped bulge that rises prominently above and below the disk. This feature, typical of spiral galaxies, consists of stars orbiting the galactic core along paths extending beyond the plane of the disk. However, UGC 10043's bulge is unusually large compared to its disk. This size discrepancy may be due to material accreted from a nearby dwarf galaxy, which could also explain the warped shape of the disk, bent upward on one end and downward on the other.
As with most Hubble images, this is a composite created from multiple snapshots taken at different wavelengths. Remarkably, the data for this image spans over two decades, with contributions from observations in both 2000 and 2023. Hubble's enduring presence has not only allowed for new and refined imagery but also established a valuable long-term archive of astronomical data.
