Astronomical Science

VISIONS is a public survey that explores five nearby star-forming molecular cloud complexes. The observing programme finished in March 2022, after collecting more than one million individual images in the near-infrared passbands J, H, and KS over a period of five years. VISIONS aims to provide a comprehensive legacy archive similar to the Two Micron All Sky Survey. In addition, multi-epoch observations facilitate proper motion measurements for sources inaccessible to Gaia. VISIONS addresses science cases related to the identification of young stars, their 3D motions, the evolution of embedded star clusters, and the characteristics of interstellar dust.
