Star explosion is most distant space object seen Oct 29, 2009
About 400,000 years later, free electrons and protons (negative and positive charges, respectively) combined to form neutral atoms, leaving the universe awash in a background radiation that we currently can detect in the microwave part of the electromagnetic spectrum (the so-called Cosmic Microwave Background). The universe stayed in this neutral stage until the first stars and galaxies light it up. (MSNBC -- Technology)
