Re: Space Microwave - Cosmic microwave, Planck & NASA's COBE
NASA's Cosmic Background Explorer (COBE) spacecraft already has detected radiation left over from the birth of the universe and Hubble can explore the universe back to when it was about 1 billion years old. Many images were already compiled from data taken between December 1989 and September 1990 by the Diffuse Infrared Background Experiment (DIRBE) on board NASA's Cosmic Background Explorer (COBE). They illustrate the steps scientists used to find the cosmic infrared background, which is a radiative fossil containing cumulative starlight which now appears in the infrared due to the cosmic red shift and by absorption and re-emission by dust in the universe since the Big Bang.The Planck mission will collect and characterise radiation from the Cosmic Microwave Background (CMB) using sensitive radio receivers operating at extremely low temperatures. Planck's objective is to analyse, with the highest accuracy ever achieved, the remnants of the radiation that filled the Universe immediately after the Big Bang, which we observe today as the Cosmic Microwave Background.

Re: Space Microwave - Cosmic microwave, Planck & NASA's COBE
Well, it doesn't mean much to me but I am sure it is important and they seem to be able to conclude a lot from the data fairly accurately. Maybe some day I'll delve into it deep enough to appreciate it more.
