Sky Viewer (testing)

Welcome to the multi-wavelength Sky Viewer.

The default view is currently set to the Rapid ASKAP Continuum Survey (RACS) centred on the large radio galaxy IC 4296,
which shows very bright radio jets emerging from near the central black hole and radio lobes with complex structure.
Switching to "rainbow" colors can be very useful to enhance the contrast.

Radio: LoTSS-DR2 144 MHz (6") TGSS 150 MHz (25") GLEAM 170-231 MHz (~120") SUMSS 843 MHz (40")
