What happened to the sun over 7,000 years ago?
Nagoya, Japan (SPX) Feb 08, 2017
An international team led by researchers at Nagoya University, along with US and Swiss colleagues, has identified a new type of solar event and dated it to the year 5480 BC; they did this by measuring carbon-14 levels in tree rings, which reflect the effects of cosmic radiation on the atmosphere at the time. They have also proposed causes of this event, thereby extending knowledge of how the sun behaves. When the activity of the sun changes, it has direct effects on the earth. For example, when th ... read more
