What gives more detailed images (higher resolution) – an iPhone or the COBE satellite camera used to propel Big Bang into the leading Cosmology concept?

Well lets find out by trying this puzzle: See if you can figure out what fairly well-known astronomical phenomenon this is a photograph of :
Here’s a hint. This first photograph of the mystery phenomenon is presented with the same angular resolution as the camera on the COBE satellite: Cosmic Background Explorer – Differential Microwave Radiometer (COBE-DMR).
(“Angular Resolution” simply means how much detail is in an image. A camera with more megapixels has a greater angular resolution; more resolution = more information.)
The COBE satellite’s data / images were described as “echoes of Big Bang” and used to first claim cosmic microwave radiation is purely from “background,” not from stars or galaxies or space dust or gas. COBE’s “background” radiation map was used to eliminate the “ Steady-State” cosmology – Big Bang’s popular competitor at the time.
Can’t see anything? Try this sharper version of the same image with a resolution identical to the best NASA technology (WMAP) for cosmic microwave radiation.
Can you guess what it is yet? or is it still too obscure? Well, when you are ready – lets take a look at it with the resolution of an ordinary camera. Continue reading
