Gould's Belt Distances Survey

The Gould's Belt Distances Survey (GOBELINS) is a survey to determine distances to stars in Gould's Belt, from parallax measurements using (radio) very-long-baseline interferometry (VLBI), utilizing the Very Long Baseline Array (VLBA). Among its targets are young stellar objects (YSOs) that are radio sources, and which do not offer parallax measurements through optical astrometry because they are obscured by dust (i.e., extinction). From distances to the YSOs, the distances to the encompassing star-forming regions is revealed.
