Radio Eyes

This is something: "http://apod.nasa.gov/apod/ap110413.html".

Imagine that you could see the night sky in the radio wavelength of the electromagnetic spectrum ...

Then you woud see this specter rising in the sky each night. This extended astronomical object is the radio image of the galaxy Centaurus A.  This link: "Centaurus A" goes to a youtube video of a 'zoom-into' this galaxy.

Your Radio Eyes would need some time to collect the 'light' from this object the picture is a composite representing over 1,000 hours of radio telescope time.
