Hubble Captures a Protoplanetary Disk

Astroturtle writes "The Hubble Space Telescope's new Advanced Camera for Surveys (ACS) has captured a detailed image of spiral rings in a distant protoplanetary disk -- the pancake-shaped cloud of gas and dust around a young star in which planets are expected to condense. But contrary to earlier suggestions, the intricate structure of this particular disk is probably caused by a nearby companion star rather than by embedded planets starting to form."
