NASA launches WMAP satellite in 2001. WMAP satellite's mission is to measure the temperature of cosmic radiation in more detail than ever. Wmap satellite hovers million miles from Earth and takes picture of our cosmos. Blue and red ripples in the pictures are tiny ripples in temperature of our early universe. It looks back 13.7 billion years into the past when the Big Bang occoured.

These ripples develop into clusters of particle and become bigger and denser in the presence of gravity. Eventually galaxies and stars are form. WMAP gives us the image of the early universe.
