If you've been seeing wierd but glorious colors in the night sky during the last week, you're not alone. People all over the northern hemisphere, as far south as Mexico have been seeing rare displays of the northern lights. They're being caused by huge eruptions on the sun. An activity that happens every eleven years.
Astronomers call it solar max.
The best place to follow the fireworks is at spaceweather dot com. The site has the latest photos including this weeks monster sunsport. It's the size of 13 Earths side by side, the largest sunspot in the last ten years. Sunspots cause coronal mass ejections, otherwise known as solar flares. They hurl billion-ton clouds of electrified magnetic gas right toward earth.
