The VLA Finishes a Decade-Long Radio Map
VLASS completed observations after nearly a decade, creating a high-resolution, wide-area record of the dynamic radio sky.
Summary
VLASS completed observations after nearly a decade, creating a high-resolution, wide-area record of the dynamic radio sky.
The National Radio Astronomy Observatory announced completion of observing for the Very Large Array Sky Survey, which ran from September 2017 through February 2026. Repeated passes across most of the sky visible to the array were designed to combine wide coverage with enough resolution to identify changing and transient radio sources. The data set supports follow-up work across astronomy rather than a single discovery. Completion of observations is a milestone; calibration, analysis, and scientific use continue.
