Big Bang radiation, mapped by Planck telescope

Mar 22 (): Big Bang radiation, the oldest light to shine through the universe was mapped by the scientists at the European Space Agency, ESA Planck satellite and released on Thursday.

ESA’s Planck satellite is a cosmic background mapper and was launched four years ago along with an infra red space telescope named Herschel. Both are focusing on the darkest, coldest and oldest parts of the universe to study dark matter and to learn more about the birth of stars and galaxies. They have gathered data of the all-sky image of radiation left over from the Big Bang and has compiled all the data into a 50-million pixel.

Jean-Jacques Dordain, the director general of the agency told the finding was a giant leap in their understanding of the origins of the Universe.

The new results from a look into the split second after the Big Bang show the universe is 80 million years older than earlier thought but the core concepts of the cosmos how it began, what it is made of and where it is going seem to be on the right track. So, from the results, 80 million years is added to the age of universe, putting the age of the universe as 13.81 billion years old.

At that time, the young Universe was filled with a hot dense broth of interacting electrons, protons and photons at about 2700 degrees Celsius. The light was set free, when the protons and electrons joined to form hydrogen atoms.

As the Universe expanded, this light today has been stretched out to microwave wavelengths, equivalent to a temperature of just 2.7 degrees above absolute zero.

Another mystery Planck will investigate is known as inflation. This is a hypothesis that the universe underwent a catastrophic expansion a split second after the Big Bang.

Herschel and Planck are designed in such a way to help scientists unravel the mysteries of the Big Bang theory by looking back into the earliest moments of the universe.
