With today's launch anniversary of Apollo 17 this is even more fitting!

Our colleague Frank Reddy at Goddard Space Flight Center has kindly cooked up some quick illustrations to drive home the massive scale of that giant looping filament on the sun that everybody was oooing and ahhhing about.

To make these images, Frank laid Earth and Jupiter along the filament. In the full-disk illustration, Earth is a mere 15 pixels in diameter! By the way, the Earth image is the famous Apollo 17 photo, much shrunken, and the Jupiter snapshot is from Cassin

This beautiful picture taken by Marketa Stancykova of solar wind buffeting Earth's magnetic field and stirring up auroras around the Arctic Circle. A beacon of light from the John Lennon memorial Imagine Peace Tower pointed to the display over Reykjavik, Iceland, on November 11, 2010. "The combination of the beacon and the Northern Lights resembled a beautiful flower in the sky--a nice tribute to Lennon," says the photographer.

On October 29, 2010 Helge Mortensen from Kattfjordvannet, ouside Troms, Norway took this beautiful picture. He said that the activity was very slow and the forecast was quite accurate.
