The team of the probe (), of the NASA, could make the first detection of helium. By this helium, they have determinated how many years ago was the big bang occur and due to this an estimate age of the universe.
Finally, the NASA informed us about this saying the following words: "The light we see today as the cosmic microwave background, has traveled over 13 billion years to reach us."
The determinated age of the universe is 13.7 billion years old with a small percantege error.
