WMAP Revolutionary Invention of 21st Century

WMAP-Wilkinson Microwave Anisotropy Probe

The scientists have yet lot to discover about Dark Energy and Dark Matter. A new device is helping them to learn more about them. It is called Wilkinson Microwave Anisotropy Probe (WMAP).

It is one the great astronomical breakthroughs of 21st century. It is a NASA satellite that is mapping the early universe. By analyzing those images scientists can find out what was the expansion rate, the composition of universe and above all the complete state of early universe. Nothing can give us a clearer image left by the big-bang, than WMAP.

This energy is called cosmic microwave background. WMAP measures temperature differences between cosmic microwave backgrounds. Blue areas are slightly colder than average temp and red area are hotter than average temperature. WMAP can measure temperature differences between 1/1000 of degrees. The sensitivity of WMAP helps the scientists to calculate the ratio of dark matter to Dark Energy.
