RECONS Mission Statement

The purpose of RECONS is to understand the nature of the Sun's nearest stellar neighbors, both individually and as a population. Our primary goals are to discover ``missing'' members of the stellar sample within 10 parsecs (32.6 light years), and to characterize all stars and their environments within that distance limit. New members are found via astrometric, photometric, and spectroscopic techniques, and through searches for stellar, brown dwarf, and planetary companions at small and large separations. Characterization includes photometry and spectroscopy at both optical and infrared wavelengths, as well as determinations of the luminosity function, mass function, and multiplicity fraction of the nearby stars. RECONS is currently extending survey work to 25 parsecs in an effort to understand the Sun's and Earth's places among a larger population of our neighbors.


We request that if you use data from this website, please acknowledge RECONS and reference www.recons.org

Current support for RECONS comes from the National Science Foundation. Our primary observing programs are carried out via the SMARTS Consortium, which operates four telescopes in the Chilean Andes under the auspices of National Optical Astronomy Observatory and the National Science Foundation.

about the logo

The RECONS logo image is an infrared picture of the Alpha Centauri system taken while observing at the Cerro Tololo Inter-american Observatory near La Serena, Chile. The mirror cover at the 1.5m telescope, which has segments much like flower petals, was partially closed, causing the diffraction effects seen for each of the two stars, Alpha Centauri A and B. These two stars and Proxima Centauri (beyond the field of view) comprise the nearest stellar system to the Sun, which is, in fact, a triple star system.
