Astronomy is undergoing a major paradigm shift. The next-generation astronomy will cover most of the sky at fine resolution in many wavelengths, from X-rays, through ultraviolet, optical, and infrared. Several multi-wavelength projects are under way or have already been completed: SDSS, GALEX, 2MASS, GSC-2, POSS2, ROSAT, FIRST and MIGHTEE. Each will be surveying a large fraction of the sky. Together they will yield a Digital Sky, of interoperating multi-terabyte databases. With the availability of this huge amount of data, the way we do astrophysics will inevitably be changed to encompass multi-wavelength analysis. Using a simple case of a bent radio source, we demonstrate the usefulness of carrying out multi-wavelength analysis in tracing cluster environment.
