Using meteorites to investigate the sun's solar activity
A Finnish-led international team has used meteorites to investigate the sun's solar activity of past centuries.
Ilya Usoskin at Finland's Sodankyla Geophysical Observatory and colleagues compared the amount of Titanium 44 in 19 meteorites that have fallen to the Earth the past 240 years. They said their findings confirm that solar activity increased strongly during the 20th century. They also find the sun has been particularly active during the past few decades. Source
