The Extragalactic Sky at 74 MHz
This image shows the sky as seen by the VLA at 74 MHz. This image is part of a large survey of the northern sky undertaken at the VLA. None of the objects visible are stars. Rather they are the cores of active galaxies (active galactic nuclei or AGN) probably located about halfway across the observable Universe.
This image is one of the fields acquired as part of the VLA Low-frequency Sky Survey (VLSS). The VLSS is a B-configuration survey of the sky accessible to the VLA, with an angular resolution of 80" and a sensitivity target (1sigma) of 0.1 Jy/beam.
