Top left: A normal ground-based infrared image (from the 2MASS survey) shows a wide binary system. Top right: Gemini adaptive optics partially corrects for blurring by the Earth's atmosphere, resolving one star in the wide binary into a close pair of stars. Bottom left: A longer exposure with Gemini adaptive optics reveals a fainter extended object near the upper close pair. Bottom right: A close-up of this faint object shows it to be an edge-on protoplanetary disk.

A close-up near-infrared image of the edge-on protoplanetary disk discovered with Gemini adaptive optics. The disk appears as a dark lane, and the star is hidden behind it. The two nebulosities on either side of the disk are produced by light from the star reflecting off the top and bottom of the disk.
