Getting Ready To Map The (Visible) Universe

phanki writes "The Arecibo Observatory is gearing up to map the universe soon. This article talks about the university getting a set of new radio recievers to complete the background work for the mapping process. So very soon we may have the map for the Andromeda !"

Of course it was an over-generalization, but in and around Pittsburgh, PA, it holds some water as nearly everything is ClearChannel or Infinity:

WDVE - Rock (CC)

WXDX - Modern Rock (CC)

WWSW - Oldies (CC)

WKST - Pop (CC)

WJJJ - HipHop/R&B (CC)

WBZZ - Pop (Infinity)

WDSY - Country (Infinity)

WZPT - 80's/90's Variety (Infinity)

Local:

WRRK - Classic Rock (Steel City Media)

WAMO - HipHop/R&B (Sheridan)

WLTJ - Lite Rock (Local)

WSHH - Soft Rock (Local)

WYEP - Adult Alternative (Public)

They're probably using "visible" to mean visible to the telescope, due to the fact that Arecibo is a fixed dish with only movable antennas, it can only see a fraction of the entire sky.

Very good points. There are also many other galactic objects that block our view, like Bok Globules, and large nebulae like the Eagle Nebula.

True, those objects block our view at optical wavelengths, but they can be transparent (well, optically thin) at submillimetre wavelengths. I work for the James Clerk Maxwell Telescope, which is the world's largest single-dish submillimetre-wave telescope. The JCMT has, for example, seen into the cores of the famous pillars in the Eagle Nebula.
