Completion of a landmark radio campaign
The National Radio Astronomy Observatory, operated under the U.S. National Science Foundation, has finalized the observing phase of the Very Large Array Sky Survey (VLASS). The effort systematically scanned the accessible sky using radio wavelengths over a multi-year schedule.
Setting new standards in radio astronomy
The resulting survey is regarded as the most detailed radio mapping of the sky ever undertaken. By pairing high angular resolution with extensive spatial coverage, it provides an unmatched record of the dynamic radio universe.
- Full sky captured by the Very Large Array instrument
- Greatest level of detail achieved for any wide-area radio observation
- Resource for studying variable and transient cosmic radio sources
Researchers anticipate that the compiled datasets will support a wide range of future investigations, since they document both stable cosmic structures and short-term changes. Public release of the survey catalogs is intended to aid scientists worldwide in follow-up studies.
