THERE is a new forecast from a panel of international scientists who study the sun. In a media release from Science@NASA, Tony Phillips explains they predict that the sun will remain generally calm for at least another year and this means low solar activity which can have “a profound effect on Earth’s atmosphere, allowing it to cool and contract”.
Summarizing comment from the expert panel, Dr Phillips explains that “cosmic rays that are normally pushed back by solar wind instead intrude on the near-Earth environment.
The graph shows yearly-averaged sunspot numbers from 1610 to 2008. Researchers believe upcoming Solar Cycle 24 will be similar to the cycle that peaked in 1928, marked by a red arrow.
