Age of the Universe?

The Universe is an interesting subject to all. The curious people always try to find it's new information. One of the most common information in Universe age. Age may only be a number, but when it comes to the age of the universe, it's a pretty important one. Researchers are always trying to find the solution. The cosmic microwave background has been observed on many missions. One of the most famous space-faring mission was NASA's Cosmic Background Explorer( COBE)  satellite, which mapped the sky in the 1990s.

Several other missions have followed in COBE's footstep, such as the BOOMERanG Exeriment ( Balloon Observations of Millimetric Extragalactic Radiation and Geophysics), NASA's Wilkinson Microwave Anisotrophy Probe( WMAP) and the Eureopean Space Agency's Planck satellite.

Plack's observation, first released in 2013, mapped the background in unprecedented detail and revealed that  the universe was older than previously thought: 13.82 billion years old, rather than 13.7 billion years old.

The universe has only two things existed. One is Energy and other in Matter. The interesting thing is that: Only it 5% is made up of matter such as planets, stars and galaxies. And 95% are Energy.
