Sun More Active Now Than Ever

Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star’s activity in the past. They say that over the last century the number of sunspots rose at the same time that the Earth’s climate became steadily warmer. This trend is being amplified by gases from fossil fuel burning, they argue.

Who can enjoy our Sun now? It’s full of blemishes! To see the sunspots yourself, you can take a picture of the sun with a camera (though not pointing the it -directly- at the sun) and viewing the image afterwards. If it’s not too bright, the spots should be fairly visible.
