A ground-based telescopic photograph of the peculiar galaxy Arp 220 (image taken by K. Borne, H. Levison, and R. Lucas at USNO Flagstaff Station, Arizona) shows a curious double-lobed structure. This structure was first interpreted as two galaxies merging together, until subsequent observations with highly sensitive CCD detectors revealed a dust lane down the center which made the galaxy appear double lobed.
