Scientists have discovered a detail in Kepler’s 400-year-old sun sketch that no one noticed for centuries
A 417-year-old drawing by Johannes Kepler has just helped solve a major solar puzzle. The 1607 sketch features sunspots that give scientists important insights into how the Sun behaved during the ...
Sunspot cycles Images captured by SOHO's Extreme Ultraviolet Imaging Telescope demonstrate the changing face of our Sun. The brightest images occur during the solar maximum when the Sun’s magnetic ...
Sunspots change in number depending on how much magnetic activity the solar dynamo generates. But there's not total chaos: These changes occur in a cycle, which lasts about 11 years on average. The ...
The study of the Sun’s long-term variation over a millennium by means of super computer modelling showed that during a time period of the Maunder Minimum type, the magnetic field may hide at the ...
